I enjoyed the post. I was about to link the "Let Me Speak Freely" paper and "Say What You Mean" response from dottxt, but that's already been posted in the comments.

I'm a huge fan of structured outputs, but also recently started splitting both steps, and I think it has a bunch of upsides normally not discussed:

1. Separate concerns, schema validation errors don't invalidate the whole LLM response. If the only error is in generating schema-compliant tokens (something I've seen frequently), retries are much cheaper.

2. Having the original response as free text AND the structured output has value.

3. In line with point 1, it allows using a more expensive (reasoning) model for free-text generation, then a smaller model like gemini-2.5-flash to convert the outputs to structured text.
