 ### Linting
 
 Linting for this project is done via a combination of [Black](https://black.readthedocs.io/en/stable/), [isort](https://pycqa.github.io/isort/), [flake8](https://flake8.pycqa.org/en/latest/), and [mypy](http://mypy-lang.org/).

-This can be very helpful when you've made changes to only certain parts of the project and want to ensure your changes meet the linting standards without having to check the entire codebase.
-
 We recognize linting can be annoying - if you do not want to do it, please contact a project maintainer, and they can help you with it. We do not want this to be a blocker for good code getting contributed.
 
-### Spellcheck
-
-Spellchecking for this project is done via [codespell](https://github.com/codespell-project/codespell).
-Note that `codespell` finds common typos, so could have false-positive (correctly spelled but rarely used) and false-negatives (not finding misspelled) words.
-
-To check spelling for this project:
-
-```bash
-make spell_check
-```
-
-To fix spelling in place:
-
-```bash
-make spell_fix
-```
-
-If codespell is incorrectly flagging a word, you can skip spellcheck for that word by adding it to the codespell config in the `pyproject.toml` file.

 ## Documentation
 
-While the code is split between `langchain` and `langchain.experimental`, the documentation is one holistic thing.
-This covers how to get started contributing to documentation.
-
 ### Contribute Documentation
 
-The docs directory contains Documentation and API Reference.
+Docs are largely autogenerated by [sphinx](https://www.sphinx-doc.org/en/master/) from the code.
 
-Documentation is built using [Docusaurus 2](https://docusaurus.io/).
-
-API Reference are largely autogenerated by [sphinx](https://www.sphinx-doc.org/en/master/) from the code.
 For that reason, we ask that you add good documentation to all classes and methods.
 
 Similar to linting, we recognize documentation can be annoying. If you do not want to do it, please contact a project maintainer, and they can help you with it. We do not want this to be a blocker for good code getting contributed.
 
 ### Build Documentation Locally
 
-In the following commands, the prefix `api_` indicates that those are operations for the API Reference.
-
 Before building the documentation, it is always a good idea to clean the build directory:
 
 ```bash
 make docs_clean
-make api_docs_clean
 ```
 
-Next, you can build the documentation as outlined below:
-
-```bash
-make docs_build
-make api_docs_build

-## 🚨Breaking Changes for select chains (SQLDatabase) on 7/28
-
-In an effort to make `langchain` leaner and safer, we are moving select chains to `langchain_experimental`.
-This migration has already started, but we are remaining backwards compatible until 7/28.
-On that date, we will remove functionality from `langchain`.
-Read more about the motivation and the progress [here](https://github.com/hwchase17/langchain/discussions/8043).
-Read how to migrate your code [here](MIGRATE.md).

 ## Building an application
 
-Now we can start building our language model application. LangChain provides many modules that can be used to build language model applications.
-Modules can be used as stand-alones in simple applications and they can be combined for more complex use cases.
-
-The core building block of LangChain applications is the LLMChain.
-This combines three things:
-- LLM: The language model is the core reasoning engine here. In order to work with LangChain, you need to understand the different types of language models and how to work with them.
-- Prompt Templates: This provides instructions to the language model. This controls what the language model outputs, so understanding how to construct prompts and different prompting strategies is crucial.
-- Output Parsers: These translate the raw response from the LLM to a more workable format, making it easy to use the output downstream.
-
-In this getting started guide we will cover those three components by themselves, and then cover the LLMChain which combines all of them.
-Understanding these concepts will set you up well for being able to use and customize LangChain applications.
-Most LangChain applications allow you to configure the LLM and/or the prompt used, so knowing how to take advantage of this will be a big enabler.
+Now we can start building our language model application. LangChain provides many modules that can be used to build language model applications. Modules can be used as stand-alones in simple applications and they can be combined for more complex use cases.
 
 ## LLMs
+#### Get predictions from a language model
 
-There are two types of language models, which in LangChain are called:
+The basic building block of LangChain is the LLM, which takes in text and generates more text.
 
-- LLMs: this is a language model which takes a string as input and returns a string
-- ChatModels: this is a language model which takes a list of messages as input and returns a message
+As an example, suppose we're building an application that generates a company name based on a company description. In order to do this, we need to initialize an OpenAI model wrapper. In this case, since we want the outputs to be MORE random, we'll initialize our model with a HIGH temperature.
 
-The input/output for LLMs is simple and easy to understand - a string.
-But what about ChatModels? The input there is a list of `ChatMessage`s, and the output is a single `ChatMessage`.
-A `ChatMessage` has two required components:
+import LLM from "@snippets/get_started/quickstart/llm.mdx"
 
-- `content`: This is the content of the message.
-- `role`: This is the role of the entity from which the `ChatMessage` is coming from.
+<LLM/>
 
-LangChain provides several objects to easily distinguish between different roles:
+## Chat models
 
-- `HumanMessage`: A `ChatMessage` coming from a human/user.
-- `AIMessage`: A `ChatMessage` coming from an AI/assistant.
-- `SystemMessage`: A `ChatMessage` coming from the system.
-- `FunctionMessage`: A `ChatMessage` coming from a function call.
+Chat models are a variation on language models. While chat models use language models under the hood, the interface they expose is a bit different: rather than expose a "text in, text out" API, they expose an interface where "chat messages" are the inputs and outputs.
 
-If none of those roles sound right, there is also a `ChatMessage` class where you can specify the role manually.
-For more information on how to use these different messages most effectively, see our prompting guide.
+You can get chat completions by passing one or more messages to the chat model. The response will be a message. The types of messages currently supported in LangChain are `AIMessage`, `HumanMessage`, `SystemMessage`, and `ChatMessage` -- `ChatMessage` takes in an arbitrary role parameter. Most of the time, you'll just be dealing with `HumanMessage`, `AIMessage`, and `SystemMessage`.
 
-LangChain exposes a standard interface for both, but it's useful to understand this difference in order to construct prompts for a given language model.
-The standard interface that LangChain exposes has two methods:
-- `predict`: Takes in a string, returns a string
-- `predict_messages`: Takes in a list of messages, returns a message.
-
-Let's see how to work with these different types of models and these different types of inputs.
-First, let's import an LLM and a ChatModel.
-
-import ImportLLMs from "@snippets/get_started/quickstart/import_llms.mdx"
-
-<ImportLLMs/>
-
-The `OpenAI` and `ChatOpenAI` objects are basically just configuration objects.
-You can initialize them with parameters like `temperature` and others, and pass them around.
-
-Next, let's use the `predict` method to run over a string input.
-
-import InputString from "@snippets/get_started/quickstart/input_string.mdx"
-
-<InputString/>
-
-Finally, let's use the `predict_messages` method to run over a list of messages.
-
-import InputMessages from "@snippets/get_started/quickstart/input_messages.mdx"
-
-<InputMessages/>
-
-For both these methods, you can also pass in parameters as key word arguments.
-For example, you could pass in `temperature=0` to adjust the temperature that is used from what the object was configured with.
-Whatever values are passed in during run time will always override what the object was configured with.
+import ChatModel from "@snippets/get_started/quickstart/chat_model.mdx"
 
+<ChatModel/>
 
 ## Prompt templates
 
-Most LLM applications do not pass user input directly into an LLM. Usually they will add the user input to a larger piece of text, called a prompt template, that provides additional context on the specific task at hand.
+Most LLM applications do not pass user input directly into to an LLM. Usually they will add the user input to a larger piece of text, called a prompt template, that provides additional context on the specific task at hand.
 
 In the previous example, the text we passed to the model contained instructions to generate a company name. For our application, it'd be great if the user only had to provide the description of a company/product, without having to worry about giving the model instructions.
 
-PromptTemplates help with exactly this!
-They bundle up all the logic for going from user input into a fully formatted prompt.
-This can start off very simple - for example, a prompt to produce the above string would just be:
-
 import PromptTemplateLLM from "@snippets/get_started/quickstart/prompt_templates_llms.mdx"
 import PromptTemplateChatModel from "@snippets/get_started/quickstart/prompt_templates_chat_models.mdx"
 
+<Tabs>
+    <TabItem value="llms" label="LLMs" default>
+
+With PromptTemplates this is easy! In this case our template would be very simple:
+
 <PromptTemplateLLM/>
+</TabItem>
+<TabItem value="chat_models" label="Chat models">
 
-However, the advantages of using these over raw string formatting are several.
-You can "partial" out variables - eg you can format only some of the variables at a time.
-You can compose them together, easily combining different templates into a single prompt.
-For explanations of these functionalities, see the [section on prompts](/docs/modules/model_io/prompts) for more detail.
+Similar to LLMs, you can make use of templating by using a `MessagePromptTemplate`. You can build a `ChatPromptTemplate` from one or more `MessagePromptTemplate`s. You can use `ChatPromptTemplate`'s `format_messages` method to generate the formatted messages.
 
-PromptTemplates can also be used to produce a list of messages.
-In this case, the prompt not only contains information about the content, but also each message (its role, its position in the list, etc)
-Here, what happens most often is a ChatPromptTemplate is a list of ChatMessageTemplates.
-Each ChatMessageTemplate contains instructions for how to format that ChatMessage - its role, and then also its content.
-Let's take a look at this below:
+Because this is generating a list of messages, it is slightly more complex than the normal prompt template which is generating only a string. Please see the detailed guides on prompts to understand more options available to you here.
 
 <PromptTemplateChatModel/>
+    </TabItem>
+</Tabs>
 
-ChatPromptTemplates can also include other things besides ChatMessageTemplates - see the [section on prompts](/docs/modules/model_io/prompts) for more detail.
+## Chains
 
-## Output Parsers
+Now that we've got a model and a prompt template, we'll want to combine the two. Chains give us a way to link (or chain) together multiple primitives, like models, prompts, and other chains.
 
-OutputParsers convert the raw output of an LLM into a format that can be used downstream.
-There are few main type of OutputParsers, including:
+import ChainLLM from "@snippets/get_started/quickstart/chains_llms.mdx"
+import ChainChatModel from "@snippets/get_started/quickstart/chains_chat_models.mdx"
 
-- Convert text from LLM -> structured information (eg JSON)
-- Convert a ChatMessage into just a string
-- Convert the extra information returned from a call besides the message (like OpenAI function invocation) into a string.
+<Tabs>
+<TabItem value="llms" label="LLMs" default>
 
-For full information on this, see the [section on output parsers](/docs/modules/model_io/output_parsers)
+The simplest and most common type of chain is an LLMChain, which passes an input first to a PromptTemplate and then to an LLM. We can construct an LLM chain from our existing model and prompt template.
 
-In this getting started guide, we will write our own output parser - one that converts a comma separated list into a list.
+<ChainLLM/>
 
-import OutputParser from "@snippets/get_started/quickstart/output_parser.mdx"
+There we go, our first chain! Understanding how this simple chain works will set you up well for working with more complex chains.
 
-<OutputParser/>
+</TabItem>
+<TabItem value="chat_models" label="Chat models">
 
-## LLMChain
+The `LLMChain` can be used with chat models as well:
 
-We can now combine all these into one chain.
-This chain will take input variables, pass those to a prompt template to create a prompt, pass the prompt to an LLM, and then pass the output through an (optional) output parser.
-This is a convenient way to bundle up a modular piece of logic.
-Let's see it in action!
+<ChainChatModel/>
+</TabItem>
+</Tabs>

+## Agents
 
-<LLMChain/>
+import AgentLLM from "@snippets/get_started/quickstart/agents_llms.mdx"
+import AgentChatModel from "@snippets/get_started/quickstart/agents_chat_models.mdx"
 
-## Next Steps
+Our first chain ran a pre-determined sequence of steps. To handle complex workflows, we need to be able to dynamically choose actions based on inputs.
 
-This is it!
-We've now gone over how to create the core building block of LangChain applications - the LLMChains.
-There is a lot more nuance in all these components (LLMs, prompts, output parsers) and a lot more different components to learn about as well.
-To continue on your journey:
+Agents do just this: they use a language model to determine which actions to take and in what order. Agents are given access to tools, and they repeatedly choose a tool, run the tool, and observe the output until they come up with a final answer.

-- Learn the other [key components](/docs/modules)
-- Check out our [helpful guides](/docs/guides) for detailed walkthroughs on particular topics
-- Explore [end-to-end use cases](/docs/use_cases)
+To load an agent, you need to choose a(n):
+- LLM/Chat model: The language model powering the agent.
+- Tool(s): A function that performs a specific duty. This can be things like: Google Search, Database lookup, Python REPL, other chains. For a list of predefined tools and their specifications, see the [Tools documentation](/docs/modules/agents/tools/).
+- Agent name: A string that references a supported agent class. An agent class is largely parameterized by the prompt the language model uses to determine which action to take. Because this notebook focuses on the simplest, highest level API, this only covers using the standard supported agents. If you want to implement a custom agent, see [here](/docs/modules/agents/how_to/custom_agent.html). For a list of supported agents and their specifications, see [here](/docs/modules/agents/agent_types/).
+
+For this example, we'll be using SerpAPI to query a search engine.
+
+You'll need to install the SerpAPI Python package:
+
+```bash
+pip install google-search-results
+```
+
+And set the `SERPAPI_API_KEY` environment variable.

+
+## Memory
+
+The chains and agents we've looked at so far have been stateless, but for many applications it's necessary to reference past interactions. This is clearly the case with a chatbot for example, where you want it to understand new messages in the context of past messages.
+
+The Memory module gives you a way to maintain application state. The base Memory interface is simple: it lets you update state given the latest run inputs and outputs and it lets you modify (or contextualize) the next input using the stored state.
+
+There are a number of built-in memory systems. The simplest of these are is a buffer memory which just prepends the last few inputs/outputs to the current input - we will use this in the example below.
+
+import MemoryLLM from "@snippets/get_started/quickstart/memory_llms.mdx"
+import MemoryChatModel from "@snippets/get_started/quickstart/memory_chat_models.mdx"
+
+<Tabs>
+<TabItem value="llms" label="LLMs" default>
+
+<MemoryLLM/>
+</TabItem>
+<TabItem value="chat_models" label="Chat models">
+
+You can use Memory with chains and agents initialized with chat models. The main difference between this and Memory for LLMs is that rather than trying to condense all previous messages into a string, we can keep them as their own unique memory object.

-# Evaluation
-
-Language models can be unpredictable. This makes it challenging to ship reliable applications to production, where repeatable, useful outcomes across diverse inputs are a minimum requirement. Tests help demonstrate each component in an LLM application can produce the required or expected functionality. These tests also safeguard against regressions while you improve interconnected pieces of an integrated system. However, measuring the quality of generated text can be challenging. It can be hard to agree on the right set of metrics for your application, and it can be difficult to translate those into better performance. Furthermore, it's common to lack sufficient evaluation data to adequately test the range of inputs and expected outputs for each component when you're just getting started. The LangChain community is building open source tools and guides to help address these challenges.
-
-LangChain exposes different types of evaluators for common types of evaluation. Each type has off-the-shelf implementations you can use to get started, as well as an
- extensible API so you can create your own or contribute improvements for everyone to use. The following sections have example notebooks for you to get started.
-
-- [String Evaluators](/docs/guides/evaluation/string/): Evaluate the predicted string for a given input, usually against a reference string
-- [Trajectory Evaluators](/docs/guides/evaluation/trajectory/): Evaluate the whole trajectory of agent actions
-- [Comparison Evaluators](/docs/guides/evaluation/comparison/): Compare predictions from two runs on a common input
-
-
-This section also provides some additional examples of how you could use these evaluators for different scenarios or apply to different chain implementations in the LangChain library. Some examples include:
-
-- [Preference Scoring Chain Outputs](/docs/guides/evaluation/examples/comparisons): An example using a comparison evaluator on different models or prompts to select statistically significant differences in aggregate preference scores

 # Agents
 
-The core idea of agents is to use an LLM to choose a sequence of actions to take.
-In chains, a sequence of actions is hardcoded (in code).
-In agents, a language model is used as a reasoning engine to determine which actions to take and in which order.
+Some applications require a flexible chain of calls to LLMs and other tools based on user input. The **Agent** interface provides the flexibility for such applications. An agent has access to a suite of tools, and determines which ones to use depending on the user input. Agents can use multiple tools, and use the output of one tool as the input to the next.
 
-There are several key components here:
+There are two main types of agents:
 
-## Agent
+- **Action agents**: at each timestep, decide on the next action using the outputs of all previous actions
+- **Plan-and-execute agents**: decide on the full sequence of actions up front, then execute them all without updating the plan
 
-This is the class responsible for deciding what step to take next.
-This is powered by a language model and a prompt.
-This prompt can include things like:
+Action agents are suitable for small tasks, while plan-and-execute agents are better for complex or long-running tasks that require maintaining long-term objectives and focus. Often the best approach is to combine the dynamism of an action agent with the planning abilities of a plan-and-execute agent by letting the plan-and-execute agent use action agents to execute plans.
 
-1. The personality of the agent (useful for having it respond in a certain way)
-2. Background context for the agent (useful for giving it more context on the types of tasks it's being asked to do)
-3. Prompting strategies to invoke better reasoning (the most famous/widely used being [ReAct](https://arxiv.org/abs/2210.03629))
+For a full list of agent types see [agent types](/docs/modules/agents/agent_types/). Additional abstractions involved in agents are:
+- [**Tools**](/docs/modules/agents/tools/): the actions an agent can take. What tools you give an agent highly depend on what you want the agent to do
+- [**Toolkits**](/docs/modules/agents/toolkits/): wrappers around collections of tools that can be used together a specific use case. For example, in order for an agent to
+  interact with a SQL database it will likely need one tool to execute queries and another to inspect tables
 
-LangChain provides a few different types of agents to get started.
-Even then, you will likely want to customize those agents with parts (1) and (2).
-For a full list of agent types see [agent types](/docs/modules/agents/agent_types/)
+## Action agents
 
-## Tools
+At a high-level an action agent:
+1. Receives user input
+2. Decides which tool, if any, to use and the tool input
+3. Calls the tool and records the output (also known as an "observation")
+4. Decides the next step using the history of tools, tool inputs, and observations
+5. Repeats 3-4 until it determines it can respond directly to the user
 
-Tools are functions that an agent calls.
-There are two important considerations here:
+Action agents are wrapped in **agent executors**, which are responsible for calling the agent, getting back an action and action input, calling the tool that the action references with the generated input, getting the output of the tool, and then passing all that information back into the agent to get the next action it should take.
 
-1. Giving the agent access to the right tools
-2. Describing the tools in a way that is most helpful to the agent
+Although an agent can be constructed in many ways, it typically involves these components:
 
-Without both, the agent you are trying to build will not work.
-If you don't give the agent access to a correct set of tools, it will never be able to accomplish the objective.
-If you don't describe the tools properly, the agent won't know how to properly use them.
+- **Prompt template**: Responsible for taking the user input and previous steps and constructing a prompt
+  to send to the language model
+- **Language model**: Takes the prompt with use input and action history and decides what to do next
+- **Output parser**: Takes the output of the language model and parses it into the next action or a final answer
 
-LangChain provides a wide set of tools to get started, but also makes it easy to define your own (including custom descriptions).
-For a full list of tools, see [here](/docs/modules/agents/tools/)
+## Plan-and-execute agents
 
-## Toolkits
+At a high-level a plan-and-execute agent:
+1. Receives user input
+2. Plans the full sequence of steps to take
+3. Executes the steps in order, passing the outputs of past steps as inputs to future steps
 
-Often the set of tools an agent has access to is more important than a single tool.
-For this LangChain provides the concept of toolkits - groups of tools needed to accomplish specific objectives.
-There are generally around 3-5 tools in a toolkit.
-
-LangChain provides a wide set of toolkits to get started.
-For a full list of toolkits, see [here](/docs/modules/agents/toolkits/)
-
-## AgentExecutor
-
-The agent executor is the runtime for an agent.
-This is what actually calls the agent and executes the actions it chooses.
-Pseudocode for this runtime is below:
-
-```python
-next_action = agent.get_action(...)
-while next_action != AgentFinish:
-    observation = run(next_action)
-    next_action = agent.get_action(..., next_action, observation)
-return next_action
-```
-
-While this may seem simple, there are several complexities this runtime handles for you, including:
-
-1. Handling cases where the agent selects a non-existent tool
-2. Handling cases where the tool errors
-3. Handling cases where the agent produces output that cannot be parsed into a tool invocation
-4. Logging and observability at all levels (agent decisions, tool calls) either to stdout or [LangSmith](https://smith.langchain.com).
-
-## Other types of agent runtimes
-
-The `AgentExecutor` class is the main agent runtime supported by LangChain.
-However, there are other, more experimental runtimes we also support.
-These include:
-
-- [Plan-and-execute Agent](/docs/modules/agents/agent_types/plan_and_execute.html)
-- [Baby AGI](/docs/use_cases/autonomous_agents/baby_agi.html)
-- [Auto GPT](/docs/use_cases/autonomous_agents/autogpt.html)
+The most typical implementation is to have the planner be a language model, and the executor be an action agent. Read more [here](/docs/modules/agents/agent_types/plan_and_execute.html).
