You can also pass in custom headers and params that will be appended to all requests made by the chain, allowing it to call APIs that require authentication. For Tool s that have a coroutine implemented (the four mentioned above),. Other agents are often optimized for using tools to figure out the best response, which is not ideal in a conversational setting where you may want the agent to be able to chat with the user as well. This is a breaking change. g. Set up your search engine by following the prompts. 95 tokens per second)from langchain. )Action (action='search', action_input='') Instead, we can use the RetryOutputParser, which passes in the prompt (as well as the original output) to try again to get a better response.
