bump version to 151 (#3658)

Alternate implementation of #3452 that relies on a generic query
constructor chain and language and then has vector store-specific
translation layer. Still refactoring and updating examples but general
structure is there and seems to work s well as #3452 on exampels

+
+This page covers how to use [Metal](https://getmetal.io) within LangChain.
+
+## What is Metal?
+
+Metal is a  managed retrieval & memory platform built for production. Easily index your data into `Metal` and run semantic search and retrieval on it.
+
+![Metal](../_static/MetalDash.png)
+
+## Quick start
+
+Get started by [creating a Metal account](https://app.getmetal.io/signup).
+
+Then, you can easily take advantage of the `MetalRetriever` class to start retrieving your data for semantic search, prompting context, etc. This class takes a `Metal` instance and a dictionary of parameters to pass to the Metal API.
+
+```python
+from langchain.retrievers import MetalRetriever
+from metal_sdk.metal import Metal
+
+
+metal = Metal("API_KEY", "CLIENT_ID", "INDEX_ID");
+retriever = MetalRetriever(metal, params={"limit": 2})

+
+This page covers how to use the Prediction Guard ecosystem within LangChain.
+It is broken into two parts: installation and setup, and then references to specific Prediction Guard wrappers.
+
+## Installation and Setup
+- Install the Python SDK with `pip install predictionguard`
+- Get an Prediction Guard access token (as described [here](https://docs.predictionguard.com/)) and set it as an environment variable (`PREDICTIONGUARD_TOKEN`)
+
+## LLM Wrapper
+
+There exists a Prediction Guard LLM wrapper, which you can access with 
+```python
+from langchain.llms import PredictionGuard
+```
+
+You can provide the name of your Prediction Guard "proxy" as an argument when initializing the LLM:
+```python
+pgllm = PredictionGuard(name="your-text-gen-proxy")
+```
+
+Alternatively, you can use Prediction Guard's default proxy for SOTA LLMs:
+```python
+pgllm = PredictionGuard(name="default-text-gen")
+```
+
+You can also provide your access token directly as an argument:
+```python
+pgllm = PredictionGuard(name="default-text-gen", token="<your access token>")
+```
+
+## Example usage
+
+Basic usage of the LLM wrapper:
+```python
+from langchain.llms import PredictionGuard
+
+pgllm = PredictionGuard(name="default-text-gen")
+pgllm("Tell me a joke")
+```
+
+Basic LLM Chaining with the Prediction Guard wrapper:
+```python
+from langchain import PromptTemplate, LLMChain
+from langchain.llms import PredictionGuard
+
+template = """Question: {question}
+
+Answer: Let's think step by step."""
+prompt = PromptTemplate(template=template, input_variables=["question"])
+llm_chain = LLMChain(prompt=prompt, llm=PredictionGuard(name="default-text-gen"), verbose=True)

+If you do not wish to specify `input_variables` manually, you can also create a `PromptTemplate` using `from_template` class method. `langchain` will automatically infer the `input_variables` based on the `template` passed.
+
+```python
+template = "Tell me a {adjective} joke about {content}."
+
+prompt_template = PromptTemplate.from_template(template)
+prompt_template.input_variables
+# -> ['adjective', 'content']
+prompt_template.format(adjective="funny", content="chickens")
+# -> Tell me a funny joke about chickens.
+```
 
 You can create custom prompt templates that format the prompt in any way you want. For more information, see [Custom Prompt Templates](examples/custom_prompt_template.ipynb).
 
 
 <!-- TODO(shreya): Add link to Jinja -->
 
-:::{note}
-Currently, the template should be formatted as a Python f-string. We also support Jinja2 templates (see [Using Jinja templates](examples/custom_prompt_template.ipynb)). In the future, we will support more templating languages such as Mako.
-:::

-
-## Load a prompt template from LangChainHub
-
-LangChainHub contains a collection of prompts which can be loaded directly via LangChain.
+## Template formats
 
+By default, `PromptTemplate` will treat the provided template as a Python f-string. You can specify other template format through `template_format` argument:
 
 ```python
+# Make sure jinja2 is installed before running this
+
+jinja2_template = "Tell me a {{ adjective }} joke about {{ content }}"
+prompt_template = PromptTemplate.from_template(template=jinja2_template, template_format="jinja2")
+
+prompt_template.format(adjective="funny", content="chickens")
+# -> Tell me a funny joke about chickens.
+```
+
+Currently, `PromptTemplate` only supports `jinja2` and `f-string` templating format. If there is any other templating format that you would like to use, feel free to open an issue in the [Github](https://github.com/hwchase17/langchain/issues) page. 
+
+## Validate template
+
+By default, `PromptTemplate` will validate the `template` string by checking whether the `input_variables` match the variables defined in `template`. You can disable this behavior by setting `validate_template` to `False`
+
+```python
+template = "I am learning langchain because {reason}."
+
+prompt_template = PromptTemplate(template=template, 
+                                 input_variables=["reason", "foo"]) # ValueError due to extra variables
+prompt_template = PromptTemplate(template=template, 
+                                 input_variables=["reason", "foo"], 
+                                 validate_template=False) # No error
+```
+
+
+## Serialize prompt template
+
+You can save your `PromptTemplate` into a file in your local filesystem. `langchain` will automatically infer the file format through the file extension name. Currently, `langchain` supports saving template to YAML and JSON file. 
+
+```python
+prompt_template.save("awesome_prompt.json") # Save to JSON file
+```
+
+```python
+from langchain.prompts import load_prompt
+loaded_prompt = load_prompt("awesome_prompt.json")
+
+assert prompt_template == loaded_prompt
+```
+
+`langchain` also supports loading prompt template from LangChainHub, which contains a collection of useful prompts you can use in your project. You can read more about LangChainHub and the prompts available with it [here](https://github.com/hwchase17/langchain-hub).
+
+```python
+
 from langchain.prompts import load_prompt
 
 prompt = load_prompt("lc://prompts/conversation/prompt.json")
 prompt.format(history="", input="What is 1 + 1?")

As someone who has always fought for the safety and well-being of the American people, I believe that any plan for integrating autonomous vehicles into our high speed rail system must prioritize safety above all else. We need to ensure that these vehicles are thoroughly tested and meet strict safety standards before they are allowed on our rails. Additionally, we must invest in the necessary infrastructure to support these vehicles, such as advanced sensors and communication systems. But we must also ensure that these innovations are accessible to all Americans, not just the wealthy. That's why I propose a public-private partnership to fund and build this system, with a focus on creating good-paying jobs and expanding economic opportunities for all Americans. *smiles confidently*\n",

That's why I propose a competition, a race to see which company can create the safest and most efficient autonomous vehicles for our high speed rail system. And let me tell you, the winner will receive a huge government contract and be hailed as a hero. It's going to be tremendous, folks. *points finger*\n",
