Zander Chase	ee670c448e	Persistent Bash Shell (#3580 ) Clean up linting and make more idiomatic by using an output parser --------- Co-authored-by: FergusFettes <fergusfettes@gmail.com>	1 year ago
Davis Chase	19c85aa990	Factor out doc formatting and add validation (#3026 ) @cnhhoang850 slightly more generic fix for #2944, works for whatever the expected metadata keys are not just `source`	1 year ago
vowelparrot	5ca7ce77cd	Remove pythonrepl from LLM-MathChain (#2943 ) Use numexpr evaluate instead of the python REPL to avoid malicious code injection. Tested against the (limited) math dataset and got the same score as before. For more permissive tools (like the REPL tool itself), other approaches ought to be provided (some combination of Sanitizer + Restricted python + unprivileged-docker + ...), but for a calculator tool, only mathematical expressions should be permitted. See https://github.com/hwchase17/langchain/issues/814	1 year ago
Ankush Gola	b82cbd1be0	Use `run` and `arun` in place of `combine_docs` and `acombine_docs` (#2635 ) `combine_docs` does not go through the standard chain call path which means that chain callbacks won't be triggered, meaning QA chains won't be traced properly, this fixes that. Also fix several errors in the chat_vector_db notebook	1 year ago

yakigac	acd86d33bc	Add read only shared memory (#1491 ) Provide shared memory capability for the Agent. Inspired by #1293 . ## Problem If both Agent and Tools (i.e., LLMChain) use the same memory, both of them will save the context. It can be annoying in some cases. ## Solution Create a memory wrapper that ignores the save and clear, thereby preventing updates from Agent or Tools.	2 years ago

Ankush Gola	82baecc892	Add a SQL agent for interacting with SQL Databases and JSON Agent for interacting with large JSON blobs (#1150 ) This PR adds * `ZeroShotAgent.as_sql_agent`, which returns an agent for interacting with a sql database. This builds off of `SQLDatabaseChain`. The main advantages are 1) answering general questions about the db, 2) access to a tool for double checking queries, and 3) recovering from errors * `ZeroShotAgent.as_json_agent` which returns an agent for interacting with json blobs. * Several examples in notebooks --------- Co-authored-by: Harrison Chase <hw.chase.17@gmail.com>	2 years ago
CG80499	af8f5c1a49	Added constitutional chain. (#1147 ) - Added self-critique constitutional chain based on this [paper](https://www.anthropic.com/constitutional.pdf).	2 years 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)	2 years ago

"Only two kinds of egg-laying mammals are left on the planet today—the duck-billed platypus and the echidna, or spiny anteater." https://www.scientificamerican.com/article/extreme-monotremes/ 2. "An [Echidna] egg weighs 1.5 to 2 grams (0.05 to 0.07 oz)[[19]](https://en.wikipedia.org/wiki/Echidna#cite_note-19) and is about 1.4 centimetres (0.55 in) long." https://en.wikipedia.org/wiki/Echidna#:~:text=sleep%20is%20suppressed.-,Reproduction,a%20reptile%2Dlike%20egg%20tooth. 3.
