Back to EpisodesEP019: Function Calling Across Different AI Models
Published 5 months, 3 weeks ago
Description
Every major AI model supports function calling now — but the implementations vary wildly.

Plus: why an API gateway that normalizes function calling across providers saves you from writing four different integration layers.
