Zander Chase	8dcad0f272	Add Support for Flexible Input Format for LLM and Chat Model Runs (#4805) ... Previously, the client expected a strict 'prompt' or 'messages' format and wouldn't permit running a chat model or llm on prompts or messages (respectively). Since many datasets may want to specify custom key: string , relax this requirement. Also, add support for running a chat model on raw prompts and LLM on chat messages through their respective fallbacks.	1 year ago

Zander Chase	928cdd57a4	[Breaking] Refactor Base Tracer(#4549) ... ### Refactor the BaseTracer - Remove the 'session' abstraction from the BaseTracer - Rename 'RunV2' object(s) to be called 'Run' objects (Rename previous Run objects to be RunV1 objects) - Ditto for sessions: TracerSession*V2 -> TracerSession* - Remove now deprecated conversion from v1 run objects to v2 run objects in LangChainTracerV2 - Add conversion from v2 run objects to v1 run objects in V1 tracer	1 year ago
Zander Chase	0c6ed657ef	Convert Chain to a Chain Factory (#4605) ... ## Change Chain argument in client to accept a chain factory The `run_over_dataset` functionality seeks to treat each iteration of an example as an independent trial. Chains have memory, so it's easier to permit this type of behavior if we accept a factory method rather than the chain object directly. There's still corner cases / UX pains people will likely run into, like: - Caching may cause issues - if memory is persisted to a shared object (e.g., same redis queue) , this could impact what is retrieved - If we're running the async methods with concurrency using local models, if someone naively instantiates the chain and loads each time, it could lead to tons of disk I/O or OOM	1 year ago
Zander Chase	4ee47926ca	Add on_chat_message_start (#4499) ... ### Add on_chat_message_start to callback manager and base tracer Goal: trace messages directly to permit reloading as chat messages (store in an integration-agnostic way) Add an `on_chat_message_start` method. Fall back to `on_llm_start()` for handlers that don't have it implemented. Does so in a non-backwards-compat breaking way (for now)	1 year ago
