Langchain

For a single inference, using agent_chain.run( ... ) in langchain, for the HumanMessage + AIMessage message blocks being persisted to memory, is there a way to add metadata to those?

By metadata, I mean timestamp, etc.

Any pointers?

Not sure. I see additional kwargs on their message class, but I have a feeling it might cause errors to put things in there. Worth a shot though!

Lol. Doesn’t help. I tried where these kwargs go, or even the metadata param on the ‘run’ method, but no luck. They should provide a way to add metadata to each (Human + AI) message pair when storing to memory. Could help a lot.

Generally speaking even having access to message UUID could help so we can amend the one stored with metadata after the agent finishes generation.

When doing a call through agent, I can’t explicitly define memory. As it has to be accessed again. Maybe I can create a parallel memory.
