OpenAI structured outputs are pretty stable for me. Gemini sometimes responds with a completely different structure. Gemini 3 flash with grounding sometimes returns json inside ```json...``` causing parsing errors.

In case you're using OpenRouter, check out their new Response Healing feature that claims to solve exactly this issue.

It does NOT. Response healing only fixes JSON syntax errors, not schema differences.
