Thanks for this. Very concise and to the point. Jefe Blaize - Thanks for the help on the calculator. I couldn't find that one. Also, there is a change to the initializeAgentExecutor. Replace it with initializeAgentExecutorWithOptions. The full line should be: const executor = await initializeAgentExecutorWithOptions(tools, model, { agentType: "zero-shot-react-description", }); because of the way the agentType needs to be passed now. Hope this helps someone.
