Hi Markus,

Is Function calling now deprecated? I see openai has now introduced tools to address API Assistants. Should function calling still work or tools should be adopted.

Great videos! Thank you! Would you be able to help with an example where the Open AI functions agent uses a tool to access vector db, has conversational buffer memory and is customised with a prompt template (e.g. you are a useful X etc.)? I’ve tried but langchain docs are hard to parse 😂😅

@codingcrashcourses8533 how can you use the Functions Agent with FastAPI streaming? I'm using some previous FastAPI tutorials that were previously working fine for streaming, but no longer work with the Functions Agent. Im not sure why???

in your first example, given that the 'functions' list was about pizza, how was it able to return information about the capital of France?

How is OpenAI function different from lang chain StructureTool?

Hmm langchain feels like a hack now a days :/

Please be careful with your API key and showing it, someone may take it and abuse it, I advise changing your key now that you have made it public
