Hmm, I was expecting more of a discussion on HN for this release. I have so many question and no answer in the comments because nobody commented :P

What is this poorly documented reasoning_effort parameter and how can I use it?

Why is re-enabling markdown part of the prompt and not a parameter?

What's going on with this developer message vs. system message?

Any thoughts about the model spec's chain of command? https://cdn.openai.com/spec/model-spec-2024-05-08.html#follo...

Please HN, don't make me use X.
