Anthropic Function Calling

Apr '24 (edited) • 💬 General

If you haven't heard, Anthropic added function calling into their API. For reference, this was the legacy implementation... This is big because it takes structured JSON in the actual API, natively opposed to passing it in a message itself. This isn't the best part though... My favorite wrapper library, LlamaIndex, has a FunctionCallingAgentWorker, that handles the back and forth function calling logic!

I've tested agents prior, using Claude 3 Haiku, with the LlamaIndex ReactAgent, i didn't get the output i'd expect. It was slightly disappointing but now, the low hanging fruit is finally here and FunctionCallingAgentWorker is amazing.

Let's see how far we can push these models!
