Description

Enables native structured output support for OpenAI GPT 5.4 model.
I'm not listing gpt-5.3 as it is not recommended for API usage, and it doesn't seem like Prism tends to add model variations such as codex etc.

GPT-5.3 Chat points to the GPT-5.3 Instant snapshot currently used in ChatGPT. We recommend GPT-5.2 for API usage, but feel free to use this GPT-5.3 Chat model to test our latest improvements for chat use cases.

I think the nano and mini models are missing? Or are they aliased somehow?
