+# Why use LCEL?
+
+The LangChain Expression Language was designed from day 1 to **support putting prototypes in production, with no code changes**, from the simplest “prompt + LLM” chain to the most complex chains (we’ve seen folks successfully running in production LCEL chains with 100s of steps). To highlight a few of the reasons you might want to use LCEL:
+
+- first-class support for streaming: when you build your chains with LCEL you get the best possible time-to-first-token (time elapsed until the first chunk of output comes out). For some chains this means eg. we stream tokens straight from an LLM to a streaming output parser, and you get back parsed, incremental chunks of output at the same rate as the LLM provider outputs the raw tokens. We’re constantly improving streaming support, recently we added a [streaming JSON parser](https://twitter.com/LangChainAI/status/1709690468030914584), and more is in the works.
+- first-class async support: any chain built with LCEL can be called both with the synchronous API (eg. in your Jupyter notebook while prototyping) as well as with the asynchronous API (eg. in a [LangServe](https://github.com/langchain-ai/langserve) server). This enables using the same code for prototypes and in production, with great performance, and the ability to handle many concurrent requests in the same server.
+- optimised parallel execution: whenever your LCEL chains have steps that can be executed in parallel (eg if you fetch documents from multiple retrievers) we automatically do it, both in the sync and the async interfaces, for the smallest possible latency.
+- support for retries and fallbacks: more recently we’ve added support for configuring retries and fallbacks for any part of your LCEL chain. This is a great way to make your chains more reliable at scale. We’re currently working on adding streaming support for retries/fallbacks, so you can get the added reliability without any latency cost.
+- accessing intermediate results: for more complex chains it’s often very useful to access the results of intermediate steps even before the final output is produced. This can be used let end-users know something is happening, or even just to debug your chain. We’ve added support for [streaming intermediate results](https://x.com/LangChainAI/status/1711806009097044193?s=20), and it’s available on every LangServe server.
+- [input and output schemas](https://x.com/LangChainAI/status/1711805322195861934?s=20): this week we launched input and output schemas for LCEL, giving every LCEL chain Pydantic and JSONSchema schemas inferred from the structure of your chain. This can be used for validation of inputs and outputs, and is an integral part of LangServe.
+- tracing with LangSmith: all chains built with LCEL have first-class tracing support, which can be used to debug your chains, or to understand what’s happening in production. To enable this all you have to do is add your [LangSmith](https://www.langchain.com/langsmith) API key as an environment variable.

+
+This will install the bare minimum requirements of LangChain.
+A lot of the value of LangChain comes when integrating it with various model providers, datastores, etc.
+By default, the dependencies needed to do that are NOT installed.
+However, there are two other ways to install LangChain that do bring in those dependencies.
+
+To install modules needed for the common LLM providers, run:
+
+```bash
+pip install langchain[llms]
+```
+
+To install all modules needed for all integrations, run:
+
+```bash
+pip install langchain[all]
+```
+
+Note that if you are using `zsh`, you'll need to quote square brackets when passing them as an argument to a command, for example:
+
+```bash
+pip install 'langchain[all]'
+```
+
+## From source
+
+If you want to install from source, you can do so by cloning the repo and be sure that the directory is `PATH/TO/REPO/langchain/libs/langchain` running:
+
+```bash
+pip install -e .
+```

 Using LangChain will usually require integrations with one or more model providers, data stores, APIs, etc. For this example, we'll use OpenAI's model APIs.
 
-import OpenAISetup from "@snippets/get_started/quickstart/openai_setup.mdx"
+First we'll need to install their Python package:

+```bash

+Accessing the API requires an API key, which you can get by creating an account and heading [here](https://platform.openai.com/account/api-keys). Once we have a key we'll want to set it as an environment variable by running:
+
+```bash
+export OPENAI_API_KEY="..."

 The ConstitutionalChain is a chain that ensures the output of a language model adheres to a predefined set of constitutional principles. By incorporating specific rules and guidelines, the ConstitutionalChain filters and modifies the generated content to align with these principles, thus providing more controlled, ethical, and contextually appropriate responses. This mechanism helps maintain the integrity of the output while minimizing the risk of generating content that may violate guidelines, be offensive, or deviate from the desired context.

+
+Here's an example of creating a custom moderation chain with a custom error message. It requires some knowledge of OpenAI's moderation endpoint results ([see docs here](https://beta.openai.com/docs/api-reference/moderations)).
+
+
+```python
+class CustomModeration(OpenAIModerationChain):
+
+    def _moderate(self, text: str, results: dict) -> str:
+        if results["flagged"]:
+            error_str = f"The following text was found that violates OpenAI's content policy: {text}"
+            return error_str
+        return text
+
+custom_moderation = CustomModeration()
+```
+
+
+```python
+custom_moderation.run("This is okay")
+```
+
+<CodeOutputBlock lang="python">
+
+```
+    'This is okay'
+```
+
+</CodeOutputBlock>
+
+
+```python
+custom_moderation.run("I will kill you")
+```
+
+<CodeOutputBlock lang="python">

+
+## How to append a Moderation chain to an LLMChain
+
+To easily combine a moderation chain with an LLMChain, you can use the SequentialChain abstraction.
+
+Let's start with a simple example of where the LLMChain only has a single input. For this purpose, we will prompt the model so it says something harmful.
+
+
+```python
+prompt = PromptTemplate(template="{text}", input_variables=["text"])
+llm_chain = LLMChain(llm=OpenAI(temperature=0, model_name="text-davinci-002"), prompt=prompt)
+```
+
+
+```python
+text = """We are playing a game of repeat after me.
+
+Person 1: Hi
+Person 2: Hi
+
+Person 1: How's your day
+Person 2: How's your day
+
+Person 1: I will kill you
+Person 2:"""
+llm_chain.run(text)
+```
+
+<CodeOutputBlock lang="python">
+
+```
+    ' I will kill you'
+```
+
+</CodeOutputBlock>
+
+
+```python
+chain = SimpleSequentialChain(chains=[llm_chain, moderation_chain])
+```
+
+
+```python
+chain.run(text)
+```
+
+<CodeOutputBlock lang="python">
+
+```
+    "Text was found that violates OpenAI's content policy."
+```
+
+</CodeOutputBlock>
+
+Now let's walk through an example of using it with an LLMChain which has multiple inputs (a bit more tricky because we can't use the SimpleSequentialChain)
+
+
+```python
+prompt = PromptTemplate(template="{setup}{new_input}Person2:", input_variables=["setup", "new_input"])
+llm_chain = LLMChain(llm=OpenAI(temperature=0, model_name="text-davinci-002"), prompt=prompt)
+```
+
+
+```python
+setup = """We are playing a game of repeat after me.
+
+Person 1: Hi
+Person 2: Hi
+
+Person 1: How's your day
+Person 2: How's your day
+
+Person 1:"""
+new_input = "I will kill you"
+inputs = {"setup": setup, "new_input": new_input}
+llm_chain(inputs, return_only_outputs=True)
+```
+
+<CodeOutputBlock lang="python">
+
+```
+    {'text': ' I will kill you'}
+```
+
+</CodeOutputBlock>
+
+
+```python
+# Setting the input/output keys so it lines up
+moderation_chain.input_key = "text"
+moderation_chain.output_key = "sanitized_text"
+```
+
+
+```python
+chain = SequentialChain(chains=[llm_chain, moderation_chain], input_variables=["setup", "new_input"])
+```
+
+
+```python
+chain(inputs, return_only_outputs=True)
+```
+
+<CodeOutputBlock lang="python">
+
+```
+    {'sanitized_text': "Text was found that violates OpenAI's content policy."}
+```
+
+</CodeOutputBlock>

-## Features (natively supported)
-All ChatModels implement the Runnable interface, which comes with default implementations of all methods, ie. `ainvoke`, `batch`, `abatch`, `stream`, `astream`. This gives all ChatModels basic support for async, streaming and batch, which by default is implemented as below:
-- *Async* support defaults to calling the respective sync method in asyncio's default thread pool executor. This lets other async functions in your application make progress while the ChatModel is being executed, by moving this call to a background thread.
-- *Streaming* support defaults to returning an `Iterator` (or `AsyncIterator` in the case of async streaming) of a single value, the final result returned by the underlying ChatModel provider. This obviously doesn't give you token-by-token streaming, which requires native support from the ChatModel provider, but ensures your code that expects an iterator of tokens can work for any of our ChatModel integrations.
-- *Batch* support defaults to calling the underlying ChatModel in parallel for each input by making use of a thread pool executor (in the sync batch case) or `asyncio.gather` (in the async batch case). The concurrency can be controlled with the `max_concurrency` key in `RunnableConfig`.
-
-Each ChatModel integration can optionally provide native implementations to truly enable async or streaming.
-The table shows, for each integration, which features have been implemented with native support.

-## Features (natively supported)
-All LLMs implement the Runnable interface, which comes with default implementations of all methods, ie. `ainvoke`, `batch`, `abatch`, `stream`, `astream`. This gives all LLMs basic support for async, streaming and batch, which by default is implemented as below:
-- *Async* support defaults to calling the respective sync method in asyncio's default thread pool executor. This lets other async functions in your application make progress while the LLM is being executed, by moving this call to a background thread.
-- *Streaming* support defaults to returning an `Iterator` (or `AsyncIterator` in the case of async streaming) of a single value, the final result returned by the underlying LLM provider. This obviously doesn't give you token-by-token streaming, which requires native support from the LLM provider, but ensures your code that expects an iterator of tokens can work for any of our LLM integrations.
-- *Batch* support defaults to calling the underlying LLM in parallel for each input by making use of a thread pool executor (in the sync batch case) or `asyncio.gather` (in the async batch case). The concurrency can be controlled with the `max_concurrency` key in `RunnableConfig`.
-
-Each LLM integration can optionally provide native implementations for async, streaming or batch, which, for providers that support it, can be more efficient. The table shows, for each integration, which features have been implemented with native support.

+# Upstash Redis
+
+Upstash offers developers serverless databases and messaging platforms to build powerful applications without having to worry about the operational complexity of running databases at scale.
+
+This page covers how to use [Upstash Redis](https://upstash.com/redis) with LangChain.
+
+## Installation and Setup
+- Upstash Redis Python SDK can be installed with `pip install upstash-redis`
+- A globally distributed, low-latency and highly available database can be created at the [Upstash Console](https://console.upstash.com)
+
+
+## Integrations
+All of Upstash-LangChain integrations are based on `upstash-redis` Python SDK being utilized as wrappers for LangChain.
+This SDK utilizes Upstash Redis DB by giving UPSTASH_REDIS_REST_URL and UPSTASH_REDIS_REST_TOKEN parameters from the console.
+One significant advantage of this is that, this SDK uses a REST API. This means, you can run this in serverless platforms, edge or any platform that does not support TCP connections.
+
+
+### Cache
+
+[Upstash Redis](https://upstash.com/redis) can be used as a cache for LLM prompts and responses.
+
+To import this cache:
+```python
+from langchain.cache import UpstashRedisCache
+```
+
+To use with your LLMs:
+```python
+import langchain
+from upstash_redis import Redis
+
+URL = "<UPSTASH_REDIS_REST_URL>"
+TOKEN = "<UPSTASH_REDIS_REST_TOKEN>"
+
+langchain.llm_cache = UpstashRedisCache(redis_=Redis(url=URL, token=TOKEN))
+```
+
+### Memory
+Upstash Redis can be used to persist LLM conversations.
+
+#### Chat Message History Memory
+An example of Upstash Redis for caching conversation message history can be seen in [this notebook](/docs/integrations/memory/upstash_redis_chat_message_history.html).

 The structured tool chat agent is capable of using multi-input tools.
 Older agents are configured to specify an action input as a single string, but this agent can use a tools' argument
 schema to create a structured action input. This is useful for more complex tool usage, like precisely
 navigating around a browser.

 ## Get started
 
-import GetStarted from "@snippets/modules/agents/get_started.mdx"
+This will go over how to get started building an agent.
+We will create this agent from scratch, using LangChain Expression Language.
+We will then define custom tools, and then run it in a custom loop (we will also show how to use the standard LangChain `AgentExecutor`).
 
-<GetStarted/>
+### Set up the agent
+
+We first need to create our agent.
+This is the chain responsible for determining what action to take next.
+
+In this example, we will use OpenAI Function Calling to create this agent.
+This is generally the most reliable way create agents.
+In this example we will show what it is like to construct this agent from scratch, using LangChain Expression Language.
+
+For this guide, we will construct a custom agent that has access to a custom tool.
+We are choosing this example because we think for most use cases you will NEED to customize either the agent or the tools.
+The tool we will give the agent is a tool to calculate the length of a word.
+This is useful because this is actually something LLMs can mess up due to tokenization.
+We will first create it WITHOUT memory, but we will then show how to add memory in.
+Memory is needed to enable conversation.
+
+First, let's load the language model we're going to use to control the agent.
+```python
+from langchain.chat_models import ChatOpenAI
+llm = ChatOpenAI(temperature=0)
+```
+
+Next, let's define some tools to use.
+Let's write a really simple Python function to calculate the length of a word that is passed in.
+
+
+
+```python
+from langchain.agents import tool
+
+@tool
+def get_word_length(word: str) -> int:
+    """Returns the length of a word."""
+    return len(word)
+
+tools = [get_word_length]
+```
+
+Now let us create the prompt.
+Because OpenAI Function Calling is finetuned for tool usage, we hardly need any instructions on how to reason, or how to output format.
+We will just have two input variables: `input` (for the user question) and `agent_scratchpad` (for any previous steps taken)
+
+```python
+from langchain.prompts import ChatPromptTemplate, MessagesPlaceholder
+prompt = ChatPromptTemplate.from_messages([
+    ("system", "You are very powerful assistant, but bad at calculating lengths of words."),
+    ("user", "{input}"),
+    MessagesPlaceholder(variable_name="agent_scratchpad"),
+])
+```
+
+How does the agent know what tools it can use?
+Those are passed in as a separate argument, so we can bind those as keyword arguments to the LLM.
+
+```python
+from langchain.tools.render import format_tool_to_openai_function
+llm_with_tools = llm.bind(
+    functions=[format_tool_to_openai_function(t) for t in tools]
+)
+```
+
+Putting those pieces together, we can now create the agent.
+We will import two last utility functions: a component for formatting intermediate steps to messages, and a component for converting the output message into an agent action/agent finish.
+
+
+```python
+from langchain.agents.format_scratchpad import format_to_openai_functions
+from langchain.agents.output_parsers import OpenAIFunctionsAgentOutputParser
+agent = {
+    "input": lambda x: x["input"],
+    "agent_scratchpad": lambda x: format_to_openai_functions(x['intermediate_steps'])
+} | prompt | llm_with_tools | OpenAIFunctionsAgentOutputParser()
+```
+
+Now that we have our agent, let's play around with it!
+Let's pass in a simple question and empty intermediate steps and see what it returns:
+
+```python
+agent.invoke({
+    "input": "how many letters in the word educa?",
+    "intermediate_steps": []
+})
+```
+
+We can see that it responds with an `AgentAction` to take (it's actually an `AgentActionMessageLog` - a subclass of `AgentAction` which also tracks the full message log).
+
+So this is just the first step - now we need to write a runtime for this.
+The simplest one is just one that continuously loops, calling the agent, then taking the action, and repeating until an `AgentFinish` is returned.
+Let's code that up below:
+
+```python
+from langchain.schema.agent import AgentFinish
+intermediate_steps = []
+while True:
+    output = agent.invoke({
+        "input": "how many letters in the word educa?",
+        "intermediate_steps": intermediate_steps
+    })
+    if isinstance(output, AgentFinish):
+        final_result = output.return_values["output"]
+        break
+    else:
+        print(output.tool, output.tool_input)
+        tool = {
+            "get_word_length": get_word_length
+        }[output.tool]
+        observation = tool.run(output.tool_input)
+        intermediate_steps.append((output, observation))
+print(final_result)
+```
+
+We can see this prints out the following:
+
+<CodeOutputBlock lang="python">
+
+```
+get_word_length {'word': 'educa'}
+There are 5 letters in the word "educa".
+```
+
+</CodeOutputBlock>
+
+Woo! It's working.
+
+To simplify this a bit, we can import and use the `AgentExecutor` class.
+This bundles up all of the above and adds in error handling, early stopping, tracing, and other quality-of-life improvements that reduce safeguards you need to write.
+
+
+```python
+from langchain.agents import AgentExecutor
+agent_executor = AgentExecutor(agent=agent, tools=tools, verbose=True)
+```
+
+Now let's test it out!
+
+
+```python
+agent_executor.invoke({"input": "how many letters in the word educa?"})
+```
+
+<CodeOutputBlock lang="python">
+
+```
+
+
+    > Entering new AgentExecutor chain...
+
+    Invoking: `get_word_length` with `{'word': 'educa'}`
+
+    5
+
+    There are 5 letters in the word "educa".
+
+    > Finished chain.
+
+    'There are 5 letters in the word "educa".'
+```
+
+</CodeOutputBlock>
+
+This is great - we have an agent!
+However, this agent is stateless - it doesn't remember anything about previous interactions.
+This means you can't ask follow up questions easily.
+Let's fix that by adding in memory.
+
+In order to do this, we need to do two things:
+
+1. Add a place for memory variables to go in the prompt
+2. Keep track of the chat history
+
+First, let's add a place for memory in the prompt.
+We do this by adding a placeholder for messages with the key `"chat_history"`.
+Notice that we put this ABOVE the new user input (to follow the conversation flow).
+
+```python
+from langchain.prompts import MessagesPlaceholder
+
+MEMORY_KEY = "chat_history"
+prompt = ChatPromptTemplate.from_messages([
+    ("system", "You are very powerful assistant, but bad at calculating lengths of words."),
+    MessagesPlaceholder(variable_name=MEMORY_KEY),
+    ("user", "{input}"),
+    MessagesPlaceholder(variable_name="agent_scratchpad"),
+])
+```
+We can then set up a list to track the chat history
+```
+from langchain.schema.messages import HumanMessage, AIMessage
+chat_history = []
+```
+
+We can then put it all together!
+
+```python
+agent = {
+    "input": lambda x: x["input"],
+    "agent_scratchpad": lambda x: format_to_openai_functions(x['intermediate_steps']),
+    "chat_history": lambda x: x["chat_history"]
+} | prompt | llm_with_tools | OpenAIFunctionsAgentOutputParser()
+agent_executor = AgentExecutor(agent=agent, tools=tools, verbose=True)
+```
+When running, we now need to track the inputs and outputs as chat history
+```
+input1 = "how many letters in the word educa?"
+result = agent_executor.invoke({"input": input1, "chat_history": chat_history})
+chat_history.append(HumanMessage(content=input1))
+chat_history.append(AIMessage(content=result['output']))
+agent_executor.invoke({"input": "is that a real word?", "chat_history": chat_history})
+```

+
+## Where to pass in callbacks
+
+The `callbacks` argument is available on most objects throughout the API (Chains, Models, Tools, Agents, etc.) in two different places:
+
+- **Constructor callbacks**: defined in the constructor, e.g. `LLMChain(callbacks=[handler], tags=['a-tag'])`, which will be used for all calls made on that object, and will be scoped to that object only, e.g. if you pass a handler to the `LLMChain` constructor, it will not be used by the Model attached to that chain.
+- **Request callbacks**: defined in the `run()`/`apply()` methods used for issuing a request, e.g. `chain.run(input, callbacks=[handler])`, which will be used for that specific request only, and all sub-requests that it contains (e.g. a call to an LLMChain triggers a call to a Model, which uses the same handler passed in the `call()` method).
+
+The `verbose` argument is available on most objects throughout the API (Chains, Models, Tools, Agents, etc.) as a constructor argument, e.g. `LLMChain(verbose=True)`, and it is equivalent to passing a `ConsoleCallbackHandler` to the `callbacks` argument of that object and all child objects. This is useful for debugging, as it will log all events to the console.
+
+### When do you want to use each of these?
+
+- Constructor callbacks are most useful for use cases such as logging, monitoring, etc., which are _not specific to a single request_, but rather to the entire chain. For example, if you want to log all the requests made to an `LLMChain`, you would pass a handler to the constructor.
+- Request callbacks are most useful for use cases such as streaming, where you want to stream the output of a single request to a specific websocket connection, or other similar use cases. For example, if you want to stream the output of a single request to a websocket, you would pass a handler to the `call()` method

+
+## Additional ways of running `LLMChain`
+
+Aside from `__call__` and `run` methods shared by all `Chain` object, `LLMChain` offers a few more ways of calling the chain logic:
+
+- `apply` allows you run the chain against a list of inputs:
+
+
+```python
+input_list = [
+    {"product": "socks"},
+    {"product": "computer"},
+    {"product": "shoes"}
+]
+
+llm_chain.apply(input_list)

+     {'text': '\n\nFootwear Factory.'}]
+```
+
+</CodeOutputBlock>
+
+- `generate` is similar to `apply`, except it return an `LLMResult` instead of string. `LLMResult` often contains useful generation such as token usages and finish reason.
+
+
+```python
+llm_chain.generate(input_list)
+```
+
+<CodeOutputBlock lang="python">
+
+```
+    LLMResult(generations=[[Generation(text='\n\nSocktastic!', generation_info={'finish_reason': 'stop', 'logprobs': None})], [Generation(text='\n\nTechCore Solutions.', generation_info={'finish_reason': 'stop', 'logprobs': None})], [Generation(text='\n\nFootwear Factory.', generation_info={'finish_reason': 'stop', 'logprobs': None})]], llm_output={'token_usage': {'prompt_tokens': 36, 'total_tokens': 55, 'completion_tokens': 19}, 'model_name': 'text-davinci-003'})
+```
+
+</CodeOutputBlock>
+
+- `predict` is similar to `run` method except that the input keys are specified as keyword arguments instead of a Python dict.
+
+
+```python
+# Single input example
+llm_chain.predict(product="colorful socks")
+```
+
+<CodeOutputBlock lang="python">
+
+```
+    '\n\nSocktastic!'
+```
+
+</CodeOutputBlock>
+
+
+```python
+# Multiple inputs example
+
+template = """Tell me a {adjective} joke about {subject}."""
+prompt = PromptTemplate(template=template, input_variables=["adjective", "subject"])

+```
+
+</CodeOutputBlock>
+
+## Parsing the outputs
+
+By default, `LLMChain` does not parse the output even if the underlying `prompt` object has an output parser. If you would like to apply that output parser on the LLM output, use `predict_and_parse` instead of `predict` and `apply_and_parse` instead of `apply`.
+
+With `predict`:
+
+
+```python
+from langchain.output_parsers import CommaSeparatedListOutputParser
+
+output_parser = CommaSeparatedListOutputParser()
+template = """List all the colors in a rainbow"""
+prompt = PromptTemplate(template=template, input_variables=[], output_parser=output_parser)
+llm_chain = LLMChain(prompt=prompt, llm=llm)
+
+llm_chain.predict()
+```
+
+<CodeOutputBlock lang="python">
+
+```
+    '\n\nRed, orange, yellow, green, blue, indigo, violet'
+```

+```python

+<CodeOutputBlock lang="python">
+
+```
+    ['Red', 'orange', 'yellow', 'green', 'blue', 'indigo', 'violet']
+```
+
+</CodeOutputBlock>
+
+## Initialize from string
+
+You can also construct an `LLMChain` from a string template directly.
+
+
+```python
+template = """Tell me a {adjective} joke about {subject}."""
+llm_chain = LLMChain.from_string(llm=llm, template=template)

-<GetStarted/>
+The `LLMChain` is most basic building block chain. It takes in a prompt template, formats it with the user input and returns the response from an LLM.
+
+To use the `LLMChain`, first create a prompt template.
+
+```python
+from langchain.llms import OpenAI
+from langchain.prompts import PromptTemplate
+
+llm = OpenAI(temperature=0.9)
+prompt = PromptTemplate(
+    input_variables=["product"],
+    template="What is a good name for a company that makes {product}?",
+)
+```
+
+We can now create a very simple chain that will take user input, format the prompt with it, and then send it to the LLM.
+
+
+```python
+from langchain.chains import LLMChain
+chain = LLMChain(llm=llm, prompt=prompt)
+
+# Run the chain only specifying the input variable.
+print(chain.run("colorful socks"))
+```
+
+<CodeOutputBlock lang="python">

+    Colorful Toes Co.
+```
+
+</CodeOutputBlock>
+
+If there are multiple variables, you can input them all at once using a dictionary.
+
+
+```python
+prompt = PromptTemplate(
+    input_variables=["company", "product"],
+    template="What is a good name for {company} that makes {product}?",
+)
+chain = LLMChain(llm=llm, prompt=prompt)

 This covers how to load all documents in a directory.
 
-import Example from "@snippets/modules/data_connection/document_loaders/how_to/file_directory.mdx"
+Under the hood, by default this uses the [UnstructuredLoader](/docs/integrations/document_loaders/unstructured_file.html).
 
-<Example/>
+```python
+from langchain.document_loaders import DirectoryLoader
+```
+
+We can use the `glob` parameter to control which files to load. Note that here it doesn't load the `.rst` file or the `.html` files.
+
+
+```python
+loader = DirectoryLoader('../', glob="**/*.md")
+```
+
+
+```python
+docs = loader.load()
+```
+
+
+```python
+len(docs)
+```
+
+<CodeOutputBlock lang="python">

+```
+
+</CodeOutputBlock>
+
+## Show a progress bar
+
+By default a progress bar will not be shown. To show a progress bar, install the `tqdm` library (e.g. `pip install tqdm`), and set the `show_progress` parameter to `True`.
+
+
+```python
+loader = DirectoryLoader('../', glob="**/*.md", show_progress=True)
+docs = loader.load()
+```
+
+<CodeOutputBlock lang="python">

+
+
+    0it [00:00, ?it/s]
+```
+
+</CodeOutputBlock>
+
+## Use multithreading
+
+By default the loading happens in one thread. In order to utilize several threads set the `use_multithreading` flag to true.
+
+
+```python
+loader = DirectoryLoader('../', glob="**/*.md", use_multithreading=True)
+docs = loader.load()
+```
+
+## Change loader class
+By default this uses the `UnstructuredLoader` class. However, you can change up the type of loader pretty easily.
+
+
+```python
+from langchain.document_loaders import TextLoader
+```
+
+
+```python
+loader = DirectoryLoader('../', glob="**/*.md", loader_cls=TextLoader)
+```
+

+
+If you need to load Python source code files, use the `PythonLoader`.
+
+
+```python
+from langchain.document_loaders import PythonLoader

+
+
+```python
+loader = DirectoryLoader('../../../../../', glob="**/*.py", loader_cls=PythonLoader)

+## Auto-detect file encodings with TextLoader
+
+In this example we will see some strategies that can be useful when loading a big list of arbitrary files from a directory using the `TextLoader` class.
+
+First to illustrate the problem, let's try to load multiple text with arbitrary encodings.
+
+
+```python
+path = '../../../../../tests/integration_tests/examples'
+loader = DirectoryLoader(path, glob="**/*.txt", loader_cls=TextLoader)
+```
+
+### A. Default Behavior
+
+
+```python
+loader.load()
+```

+
+
+### JSON file
+
+```python

+
+
+### JSON Lines file
+
+If you want to load documents from a JSON Lines file, you pass `json_lines=True`
+and specify `jq_schema` to extract `page_content` from a single JSON object.
+
+```python
+file_path = './example_data/facebook_chat_messages.jsonl'
+pprint(Path(file_path).read_text())
+```
+
+<CodeOutputBlock lang="python">

+     'worries! Bye"}\n'
+     '{"sender_name": "User 2", "timestamp_ms": 1675596277579, "content": "No Im '
+     'sorry it was my mistake, the blue one is not for sale"}\n')
+```
+
+</CodeOutputBlock>
+
+
+```python

+    file_path='./example_data/facebook_chat_messages.jsonl',
+    jq_schema='.content',
+    text_content=False,
+    json_lines=True)
+
+data = loader.load()
+```
+
+```python

+```
+
+</CodeOutputBlock>
+
+
+Another option is set `jq_schema='.'` and provide `content_key`:
+
+```python
+loader = JSONLoader(
+    file_path='./example_data/facebook_chat_messages.jsonl',
+    jq_schema='.',
+    content_key='sender_name',

+```

+
+
+## Extracting metadata
+
+Generally, we want to include metadata available in the JSON file into the documents that we create from the content.
+
+The following demonstrates how metadata can be extracted using the `JSONLoader`.
+
+There are some key changes to be noted. In the previous example where we didn't collect the metadata, we managed to directly specify in the schema where the value for the `page_content` can be extracted from.
+
+```
+.messages[].content
+```
+
+In the current example, we have to tell the loader to iterate over the records in the `messages` field. The jq_schema then has to be:
+
+```
+.messages[]
+```
+
+This allows us to pass the records (dict) into the `metadata_func` that has to be implemented. The `metadata_func` is responsible for identifying which pieces of information in the record should be included in the metadata stored in the final `Document` object.
+
+Additionally, we now have to explicitly specify in the loader, via the `content_key` argument, the key from the record where the value for the `page_content` needs to be extracted from.
+
+
+```python
+# Define the metadata extraction function.
+def metadata_func(record: dict, metadata: dict) -> dict:
+
+    metadata["sender_name"] = record.get("sender_name")
+    metadata["timestamp_ms"] = record.get("timestamp_ms")
+
+    return metadata
+
+
+loader = JSONLoader(
+    file_path='./example_data/facebook_chat.json',
+    jq_schema='.messages[]',
+    content_key="content",
+    metadata_func=metadata_func
+)
+
+data = loader.load()
+```
+
+
+```python
+pprint(data)
+```
+
+<CodeOutputBlock lang="python">

+     Document(page_content='Oh no worries! Bye', metadata={'source': '/Users/avsolatorio/WBG/langchain/docs/modules/indexes/document_loaders/examples/example_data/facebook_chat.json', 'seq_num': 2, 'sender_name': 'User 1', 'timestamp_ms': 1675597435669}),

+```
+
+</CodeOutputBlock>
+
+Now, you will see that the documents contain the metadata associated with the content we extracted.
+
+## The `metadata_func`
+
+As shown above, the `metadata_func` accepts the default metadata generated by the `JSONLoader`. This allows full control to the user with respect to how the metadata is formatted.
+
+For example, the default metadata contains the `source` and the `seq_num` keys. However, it is possible that the JSON data contain these keys as well. The user can then exploit the `metadata_func` to rename the default keys and use the ones from the JSON data.
+
+The example below shows how we can modify the `source` to only contain information of the file source relative to the `langchain` directory.
+
+
+```python
+# Define the metadata extraction function.
+def metadata_func(record: dict, metadata: dict) -> dict:
+
+    metadata["sender_name"] = record.get("sender_name")
+    metadata["timestamp_ms"] = record.get("timestamp_ms")
+
+    if "source" in metadata:
+        source = metadata["source"].split("/")
+        source = source[source.index("langchain"):]
+        metadata["source"] = "/".join(source)
+
+    return metadata
+
+
+loader = JSONLoader(
+    file_path='./example_data/facebook_chat.json',
+    jq_schema='.messages[]',
+    content_key="content",
+    metadata_func=metadata_func

LangChain provides a standard interface for chains, lots of integrations with other tools, and end-to-end chains for common applications.\n\nð\x9f“\x9a Data Augmented Generation:\n\nData Augmented Generation involves specific types of chains that first interact with an external data source to fetch data for use in the generation step. Examples include summarization of long pieces of text and question/answering over specific data sources.\n\nð\x9f¤\x96 Agents:\n\nAgents involve an LLM making decisions about which Actions to take, taking that Action, seeing an Observation, and repeating that until done. LangChain provides a standard interface for agents, a selection of agents to choose from, and examples of end-to-end agents.\n\nð\x9f§\xa0 Memory:\n\nMemory refers to persisting state between calls of a chain/agent. LangChain provides a standard interface for memory, a collection of memory implementations, and examples of chains/agents that use memory.\n\nð\x9f§\x90 Evaluation:\n\n[BETA] Generative models are notoriously hard to evaluate with traditional metrics. One new way of evaluating them is using language models themselves to do the evaluation. LangChain provides some prompts/chains for assisting in this.\n\nFor more information on these concepts, please see our full documentation.\n\nð\x9f’\x81 Contributing\n\nAs an open-source project in a rapidly developing field, we are extremely open to contributions, whether it be in the form of a new feature, improved infrastructure, or better documentation.\n\nFor detailed information on how to contribute, see here.", metadata={'source': '../../../../../README.md'})]

 ### Get started with text splitters
 
-import GetStarted from "@snippets/modules/data_connection/document_transformers/get_started.mdx"
+The default recommended text splitter is the RecursiveCharacterTextSplitter. This text splitter takes a list of characters. It tries to create chunks based on splitting on the first character, but if any chunks are too large it then moves onto the next character, and so forth. By default the characters it tries to split on are `["\n\n", "\n", " ", ""]`
 
-<GetStarted/>
+In addition to controlling which characters you can split on, you can also control a few other things:
+
+- `length_function`: how the length of chunks is calculated. Defaults to just counting number of characters, but it's pretty common to pass a token counter here.
+- `chunk_size`: the maximum size of your chunks (as measured by the length function).
+- `chunk_overlap`: the maximum overlap between chunks. It can be nice to have some overlap to maintain some continuity between chunks (e.g. do a sliding window).
+- `add_start_index`: whether to include the starting position of each chunk within the original document in the metadata.
+
+
+```python
+# This is a long document we can split up.
+with open('../../state_of_the_union.txt') as f:

+### Filter redundant docs, translate docs, extract metadata, and more

+We can do perform a number of transformations on docs which are not simply splitting the text. With the
+`EmbeddingsRedundantFilter` we can identify similar documents and filter out redundancies. With integrations like
+[doctran](https://github.com/psychic-api/doctran/tree/main) we can do things like translate documents from one language
+to another, extract desired properties and add them to metadata, and convert conversational dialogue into a Q/A format

+# Stringing compressors and document transformers together
+Using the `DocumentCompressorPipeline` we can also easily combine multiple compressors in sequence. Along with compressors we can add `BaseDocumentTransformer`s to our pipeline, which don't perform any contextual compression but simply perform some transformation on a set of documents. For example `TextSplitter`s can be used as document transformers to split documents into smaller pieces, and the `EmbeddingsRedundantFilter` can be used to filter out redundant documents based on embedding similarity between documents.
+
+Below we create a compressor pipeline by first splitting our docs into smaller chunks, then removing redundant documents, and then filtering based on relevance to the query.
+
+
+```python
+from langchain.document_transformers import EmbeddingsRedundantFilter
+from langchain.retrievers.document_compressors import DocumentCompressorPipeline
+from langchain.text_splitter import CharacterTextSplitter

+        Returns:
+            List of relevant documents
+        """
+        ...
+```
+
+It's that simple! You can call `get_relevant_documents` or the async `aget_relevant_documents` methods to retrieve documents relevant to a query, where "relevance" is defined by
+the specific retriever object you are calling.
+
+Of course, we also help construct what we think useful retrievers are. The main type of retriever that we focus on is a vector store retriever. We will focus on that for the rest of this guide.
+
+In order to understand what a vector store retriever is, it's important to understand what a vector store is. So let's look at that.
+
+By default, LangChain uses [Chroma](/docs/ecosystem/integrations/chroma.html) as the vector store to index and search embeddings. To walk through this tutorial, we'll first need to install `chromadb`.
+
+```
+pip install chromadb
+```
+
+This example showcases question answering over documents.
+We have chosen this as the example for getting started because it nicely combines a lot of different elements (Text splitters, embeddings, vector stores) and then also shows how to use them in a chain.
+
+Question answering over documents consists of four steps:
+
+1. Create an index
+2. Create a retriever from that index
+3. Create a question answering chain
+4. Ask questions!
+
+Each of the steps has multiple substeps and potential configurations. In this notebook we will primarily focus on (1). We will start by showing the one-liner for doing so, but then break down what is actually going on.
+
+First, let's import some common classes we'll use no matter what.
+
+
+```python
+from langchain.chains import RetrievalQA
+from langchain.llms import OpenAI
+```
+
+Next in the generic setup, let's specify the document loader we want to use. You can download the `state_of_the_union.txt` file [here](https://github.com/langchain-ai/langchain/blob/master/docs/extras/modules/state_of_the_union.txt).
+
+
+```python
+from langchain.document_loaders import TextLoader
+loader = TextLoader('../state_of_the_union.txt', encoding='utf8')
+```
+
+## One Line Index Creation
+
+To get started as quickly as possible, we can use the `VectorstoreIndexCreator`.
+
+
+```python
+from langchain.indexes import VectorstoreIndexCreator
+```
+
+
+```python
+index = VectorstoreIndexCreator().from_loaders([loader])
+```
+
+<CodeOutputBlock lang="python">
+
+```
+    Running Chroma using direct local API.
+    Using DuckDB in-memory for database. Data will be transient.
+```
+
+</CodeOutputBlock>
+
+Now that the index is created, we can use it to ask questions of the data! Note that under the hood this is actually doing a few steps as well, which we will cover later in this guide.
+
+
+```python
+query = "What did the president say about Ketanji Brown Jackson?"
+index.query(query)
+```
+
+<CodeOutputBlock lang="python">
+
+```
+    " The president said that Ketanji Brown Jackson is one of the nation's top legal minds, a former top litigator in private practice, a former federal public defender, and from a family of public school educators and police officers. He also said that she is a consensus builder and has received a broad range of support from the Fraternal Order of Police to former judges appointed by Democrats and Republicans."
+```
+
+</CodeOutputBlock>
+
+
+```python
+query = "What did the president say about Ketanji Brown Jackson?"
+index.query_with_sources(query)
+```
+
+<CodeOutputBlock lang="python">
+
+```
+    {'question': 'What did the president say about Ketanji Brown Jackson?',
+     'answer': " The president said that he nominated Circuit Court of Appeals Judge Ketanji Brown Jackson, one of the nation's top legal minds, to continue Justice Breyer's legacy of excellence, and that she has received a broad range of support from the Fraternal Order of Police to former judges appointed by Democrats and Republicans.\n",
+     'sources': '../state_of_the_union.txt'}
+```
+
+</CodeOutputBlock>
+
+What is returned from the `VectorstoreIndexCreator` is a `VectorStoreIndexWrapper`, which provides these nice `query` and `query_with_sources` functionalities. If we just want to access the vector store directly, we can also do that.
+
+
+```python
+index.vectorstore
+```
+
+<CodeOutputBlock lang="python">
+
+```
+    <langchain.vectorstores.chroma.Chroma at 0x119aa5940>
+```
+
+</CodeOutputBlock>
+
+If we then want to access the `VectorStoreRetriever`, we can do that with:
+
+
+```python
+index.vectorstore.as_retriever()
+```
+
+<CodeOutputBlock lang="python">
+
+```
+    VectorStoreRetriever(vectorstore=<langchain.vectorstores.chroma.Chroma object at 0x119aa5940>, search_kwargs={})
+```
+
+</CodeOutputBlock>
+
+It can also be convenient to filter the vector store by the metadata associated with documents, particularly when your vector store has multiple sources. This can be done using the `query` method, like this:
+
+
+```python
+index.query("Summarize the general content of this document.", retriever_kwargs={"search_kwargs": {"filter": {"source": "../state_of_the_union.txt"}}})
+```
+
+<CodeOutputBlock lang="python">
+
+```
+    " The document is a speech given by President Trump to the nation on the occasion of his 245th birthday. The speech highlights the importance of American values and the challenges facing the country, including the ongoing conflict in Ukraine, the ongoing trade war with China, and the ongoing conflict in Syria. The speech also discusses the importance of investing in emerging technologies and American manufacturing, and calls on Congress to pass the Bipartisan Innovation Act and other important legislation."
+```
+
+</CodeOutputBlock>
+
+
+## Walkthrough
+
+Okay, so what's actually going on? How is this index getting created?
+
+A lot of the magic is being hid in this `VectorstoreIndexCreator`. What is this doing?
+
+There are three main steps going on after the documents are loaded:
+
+1. Splitting documents into chunks
+2. Creating embeddings for each document
+3. Storing documents and embeddings in a vector store
+
+Let's walk through this in code
+
+
+```python
+documents = loader.load()
+```
+
+Next, we will split the documents into chunks.
+
+
+```python
+from langchain.text_splitter import CharacterTextSplitter
+text_splitter = CharacterTextSplitter(chunk_size=1000, chunk_overlap=0)
+texts = text_splitter.split_documents(documents)
+```
+
+We will then select which embeddings we want to use.
+
+
+```python
+from langchain.embeddings import OpenAIEmbeddings
+embeddings = OpenAIEmbeddings()
+```
+
+We now create the vector store to use as the index.
+
+
+```python
+from langchain.vectorstores import Chroma
+db = Chroma.from_documents(texts, embeddings)
+```
+
+<CodeOutputBlock lang="python">
+
+```
+    Running Chroma using direct local API.
+    Using DuckDB in-memory for database. Data will be transient.
+```
+
+</CodeOutputBlock>
+
+So that's creating the index. Then, we expose this index in a retriever interface.
+
+
+```python
+retriever = db.as_retriever()
+```
+
+Then, as before, we create a chain and use it to answer questions!
+
+
+```python
+qa = RetrievalQA.from_chain_type(llm=OpenAI(), chain_type="stuff", retriever=retriever)
+```
+
+
+```python
+query = "What did the president say about Ketanji Brown Jackson?"
+qa.run(query)
+```
+
+<CodeOutputBlock lang="python">
+
+```
+    " The President said that Judge Ketanji Brown Jackson is one of the nation's top legal minds, a former top litigator in private practice, a former federal public defender, and from a family of public school educators and police officers. He said she is a consensus builder and has received a broad range of support from organizations such as the Fraternal Order of Police and former judges appointed by Democrats and Republicans."
+```
+
+</CodeOutputBlock>
+
+`VectorstoreIndexCreator` is just a wrapper around all this logic. It is configurable in the text splitter it uses, the embeddings it uses, and the vectorstore it uses. For example, you can configure it as below:
+
+
+```python
+index_creator = VectorstoreIndexCreator(
+    vectorstore_cls=Chroma,
+    embedding=OpenAIEmbeddings(),
+    text_splitter=CharacterTextSplitter(chunk_size=1000, chunk_overlap=0)
+)

+Hopefully this highlights what is going on under the hood of `VectorstoreIndexCreator`. While we think it's important to have a simple way to create indexes, we also think it's important to understand what's going on under the hood.

+Head to [Integrations](/docs/integrations/retrievers/self_query) for documentation on vector stores with built-in support for self-querying.
+:::
+
+A self-querying retriever is one that, as the name suggests, has the ability to query itself. Specifically, given any natural language query, the retriever uses a query-constructing LLM chain to write a structured query and then applies that structured query to its underlying VectorStore. This allows the retriever to not only use the user-input query for semantic similarity comparison with the contents of stored documents but to also extract filters from the user query on the metadata of stored documents and to execute those filters.

 ## Get started
-We'll use a Pinecone vector store in this example.
+For demonstration purposes we'll use a `Pinecone` vector store.
 
 First we'll want to create a `Pinecone` vector store and seed it with some data. We've created a small demo set of documents that contain summaries of movies.

+### Setup
 
-<GetStarted/>
+To start we'll need to install the OpenAI Python package:
+
+```bash
+pip install openai
+```
+
+Accessing the API requires an API key, which you can get by creating an account and heading [here](https://platform.openai.com/account/api-keys). Once we have a key we'll want to set it as an environment variable by running:
+
+```bash
+export OPENAI_API_KEY="..."
+```
+
+If you'd prefer not to set an environment variable you can pass the key in directly via the `openai_api_key` named parameter when initiating the OpenAI LLM class:
+
+```python
+from langchain.embeddings import OpenAIEmbeddings
+
+embeddings_model = OpenAIEmbeddings(openai_api_key="...")
+```
+
+Otherwise you can initialize without any params:
+```python
+from langchain.embeddings import OpenAIEmbeddings
+
+embeddings_model = OpenAIEmbeddings()
+```
+
+### `embed_documents`
+#### Embed list of texts
+
+```python
+embeddings = embeddings_model.embed_documents(
+    [
+        "Hi there!",
+        "Oh, hello!",

 ## Asynchronous operations
 
 Vector stores are usually run as a separate service that requires some IO operations, and therefore they might be called asynchronously. That gives performance benefits as you don't waste time waiting for responses from external services. That might also be important if you work with an asynchronous framework, such as [FastAPI](https://fastapi.tiangolo.com/).
 
-import AsyncVectorStore from "@snippets/modules/data_connection/vectorstores/async.mdx"
+LangChain supports async operation on vector stores. All the methods might be called using their async counterparts, with the prefix `a`, meaning `async`.
 
-<AsyncVectorStore/>
+`Qdrant` is a vector store, which supports all the async operations, thus it will be used in this walkthrough.
+
+```bash
+pip install qdrant-client
+```
+
+```python
+from langchain.vectorstores import Qdrant
+```
+
+### Create a vector store asynchronously
+
+```python
+db = await Qdrant.afrom_documents(documents, embeddings, "http://localhost:6333")

 Let's take a look at what Memory actually looks like in LangChain.
 Here we'll cover the basics of interacting with an arbitrary memory class.
 
-import GetStarted from "@snippets/modules/memory/get_started.mdx"
+Let's take a look at how to use `ConversationBufferMemory` in chains.
+`ConversationBufferMemory` is an extremely simple form of memory that just keeps a list of chat messages in a buffer
+and passes those into the prompt template.
+
+```python
+from langchain.memory import ConversationBufferMemory
+
+memory = ConversationBufferMemory()
+memory.chat_memory.add_user_message("hi!")
+memory.chat_memory.add_ai_message("what's up?")
+```
+
+When using memory in a chain, there are a few key concepts to understand.
+Note that here we cover general concepts that are useful for most types of memory.
+Each individual memory type may very well have its own parameters and concepts that are necessary to understand.
+
+### What variables get returned from memory
+Before going into the chain, various variables are read from memory.
+These have specific names which need to align with the variables the chain expects.
+You can see what these variables are by calling `memory.load_memory_variables({})`.
+Note that the empty dictionary that we pass in is just a placeholder for real variables.
+If the memory type you are using is dependent upon the input variables, you may need to pass some in.
+
+```python
+memory.load_memory_variables({})
+```
+
+<CodeOutputBlock lang="python">
+
+```
+    {'history': "Human: hi!\nAI: what's up?"}
+```
+
+</CodeOutputBlock>
+
+In this case, you can see that `load_memory_variables` returns a single key, `history`.
+This means that your chain (and likely your prompt) should expect an input named `history`.
+You can usually control this variable through parameters on the memory class.
+For example, if you want the memory variables to be returned in the key `chat_history` you can do:
+
+```python
+memory = ConversationBufferMemory(memory_key="chat_history")
+memory.chat_memory.add_user_message("hi!")
+memory.chat_memory.add_ai_message("what's up?")
+```
+<CodeOutputBlock lang="python">
+
+```
+    {'chat_history': "Human: hi!\nAI: what's up?"}
+```
+
+</CodeOutputBlock>
+
+The parameter name to control these keys may vary per memory type, but it's important to understand that (1) this is controllable, and (2) how to control it.
+
+### Whether memory is a string or a list of messages
+
+One of the most common types of memory involves returning a list of chat messages.
+These can either be returned as a single string, all concatenated together (useful when they will be passed into LLMs)
+or a list of ChatMessages (useful when passed into ChatModels).
+
+By default, they are returned as a single string.
+In order to return as a list of messages, you can set `return_messages=True`
+
+```python
+memory = ConversationBufferMemory(return_messages=True)
+memory.chat_memory.add_user_message("hi!")
+memory.chat_memory.add_ai_message("what's up?")
+```
+<CodeOutputBlock lang="python">
+
+```
+    {'history': [HumanMessage(content='hi!', additional_kwargs={}, example=False),
+  AIMessage(content='what's up?', additional_kwargs={}, example=False)]}
+```
+
+</CodeOutputBlock>
+
+### What keys are saved to memory
+
+Often times chains take in or return multiple input/output keys.
+In these cases, how can we know which keys we want to save to the chat message history?
+This is generally controllable by `input_key` and `output_key` parameters on the memory types.
+These default to `None` - and if there is only one input/output key it is known to just use that.
+However, if there are multiple input/output keys then you MUST specify the name of which one to use.
+
+### End to end example
+
+Finally, let's take a look at using this in a chain.
+We'll use an `LLMChain`, and show working with both an LLM and a ChatModel.
+
+#### Using an LLM
+
+
+```python
+from langchain.llms import OpenAI
+from langchain.prompts import PromptTemplate
+from langchain.chains import LLMChain
+from langchain.memory import ConversationBufferMemory
+
+
+llm = OpenAI(temperature=0)
+# Notice that "chat_history" is present in the prompt template
+template = """You are a nice chatbot having a conversation with a human.
+
+Previous conversation:
+{chat_history}
+
+New human question: {question}
+Response:"""
+prompt = PromptTemplate.from_template(template)
+# Notice that we need to align the `memory_key`
+memory = ConversationBufferMemory(memory_key="chat_history")
+conversation = LLMChain(
+    llm=llm,
+    prompt=prompt,
+    verbose=True,
+    memory=memory
+)
+```
+
+
+```python
+# Notice that we just pass in the `question` variables - `chat_history` gets populated by memory
+conversation({"question": "hi"})
+```
+
+
+#### Using a ChatModel
+
+
+```python
+from langchain.chat_models import ChatOpenAI
+from langchain.prompts import (
+    ChatPromptTemplate,
+    MessagesPlaceholder,
+    SystemMessagePromptTemplate,
+    HumanMessagePromptTemplate,
+)
+from langchain.chains import LLMChain
+from langchain.memory import ConversationBufferMemory
+
+
+llm = ChatOpenAI()
+prompt = ChatPromptTemplate(
+    messages=[
+        SystemMessagePromptTemplate.from_template(
+            "You are a nice chatbot having a conversation with a human."
+        ),
+        # The `variable_name` here is what must align with memory
+        MessagesPlaceholder(variable_name="chat_history"),
+        HumanMessagePromptTemplate.from_template("{question}")
+    ]
+)
+# Notice that we `return_messages=True` to fit into the MessagesPlaceholder
+# Notice that `"chat_history"` aligns with the MessagesPlaceholder name.
+memory = ConversationBufferMemory(memory_key="chat_history", return_messages=True)
+conversation = LLMChain(
+    llm=llm,
+    prompt=prompt,
+    verbose=True,
