I feel the same way about OpenAI‘s new responses API. Under the cover of DX they‘re marketing a new default, which is we hold your state and sell it back to you.
OpenAI is tedious to work with. Took me a solid day of fooling around with it before I realized the chat api and the chat completions api are two entirely different apis. Then you have the responses api which is a third thing.
The irony is that gpt4 has no clue which approach is correct. Give it the same prompt three times and you’ll get a solution that uses each of these that has a wildly different footprint, be it via function calls or system prompts, schema or no schema, etc.
