Ankush Gola	caa8e4742e	Enable streaming for OpenAI LLM (#986 ) * Support a callback `on_llm_new_token` that users can implement when `OpenAI.streaming` is set to `True`	1 year ago
Ankush Gola	bc7e56e8df	Add asyncio support for LLM (OpenAI), Chain (LLMChain, LLMMathChain), and Agent (#841 ) Supporting asyncio in langchain primitives allows for users to run them concurrently and creates more seamless integration with asyncio-supported frameworks (FastAPI, etc.) Summary of changes: LLM * Add `agenerate` and `_agenerate` * Implement in OpenAI by leveraging `client.Completions.acreate` Chain * Add `arun`, `acall`, `_acall` * Implement them in `LLMChain` and `LLMMathChain` for now Agent * Refactor and leverage async chain and llm methods * Add ability for `Tools` to contain async coroutine * Implement async SerpaPI `arun` Create demo notebook. Open questions: * Should all the async stuff go in separate classes? I've seen both patterns (keeping the same class and having async and sync methods vs. having class separation)	1 year ago
Ankush Gola	57609845df	add tracing support to langchain (#741 ) * add implementations of `BaseCallbackHandler` to support tracing: `SharedTracer` which is thread-safe and `Tracer` which is not and is meant to be used locally. * Tracers persist runs to locally running `langchain-server` Co-authored-by: Harrison Chase <hw.chase.17@gmail.com>	1 year ago

Ankush Gola	8d0869c6d3	change run to use args and kwargs (#367 ) Before, `run` was not able to be called with multiple arguments. This expands the functionality.	1 year ago

Hansen Qian	a39c998342	Add chain name to verbose logging (#214 ) Adds some context over what chain is running, thereby making it more obvious how different chains are entered and existed <img width="867" alt="Screen Shot 2022-11-28 at 11 55 34 AM" src="https://user-images.githubusercontent.com/2548973/204336849-25d87b44-6f5d-487b-b583-5455f306a470.png"> (note that the `...` is because the output is too long and VSCode truncated it)	2 years ago

Harrison Chase	b913df3774	make attrs public (#187 ) since they are used outside of the class, should be public	2 years ago
Samantha Whitmore	a408ed3ea3	Samantha/add conversation chain (#166 ) Add MemoryChain and ConversationChain as chains that take a docstore in addition to the prompt, and use the docstore to stuff context into the prompt. This can be used to have an ongoing conversation with a chatbot. Probably needs a bit of refactoring for code quality Co-authored-by: Harrison Chase <hw.chase.17@gmail.com>	2 years ago
