Hi James. Another great video! Helps understanding the concepts. A couple of questions : 1. Is it possible to wrap an Agent with several possibly custom tools as a new Tool and use it in another higher level Agent? 2. Can you make a video about the Agent visual tracing capability of LangChain? Thanks in advance

Really very well explained. Thanks a lot as it was the tchnique I was looking for. You made me save a lot of time.

what is the "description" of pre built tools. when we created `math_tool` we used "description" but when we use `load_tools`, we do not specify any "description". how the agent will infer which tool to use if we use `load_tools` feature

they use the SERP API, they can and do do this where needed, so you may have an agent that searches to retrieve info, goes into a Thought+Observation loop where it "thinks" about the info (it could pass this to another LLM like GPT-4 via an additional tool if preferred), and work through that process token limits are equal to the LLMs being used, if you have conversation history that needs to be considered too, so for GPT-4 you're at 8K, gpt-3.5-turbo is 4K

I've been trying to use the ChatConversationalAgent and I'm running into an issue where the agent decides by the second or third user prompt to stop using the formatting and so I get a ValueError that the LLM output was not formatted. This happens even with GPT-4. I'm speculating that it's because the memory the agent receives of its previous messages are not in the response format so the agent ignores its prompt and does not respond in the correct format. Is this something you guys have run into? I noticed you were not using "Chat" agents.

@Cobryis

Posted about this on the langchain discord but I'm 80% certain this is what's happening. Langchain memory is formatting assistant messages sent to OpenAI without json format so then the LLM in response returns a message not in the correct format.

Yeah this is a common problem, I haven’t had a chance to look into the best way to fix yet, but there is an output parser in the library for fixing json, it might be possible to integrate that somehow, maybe using a custom tool / agent, but I haven’t tested

Semantic search understands the meaning of search terms and returns highly relevant results.

text-davinci-003 is technically a gpt 3.5 model, but I think this is what you mean by gpt 3? In that case you are correct, that's because all of the models before gpt-3.5-turbo were standard LLM models, whereas gpt-3.5-turbo (and gpt-4) are "Chat LLMs" so the interface is slightly different via the OpenAI API. This difference is handled by using the different agents in langchain, non-chat agents for standard OpenAI LLMs, and chat agents for the Chat LLMs
