Which LLM is best for JSON output while also being fast?

I need something that can properly output strict and consistent JSON structure. Our outputs tend to be ~8000 characters ~2000 tokens, was using Gemini-3-flash-preview and Gemini 3 pro but Gemini really likes to go off the rails and hallucinate, a little bit.

If you have used a model that outputs strict and consistent JSON structure, let me know.

we've tried adjusting everything with gemini but still end up getting hallucinations and many people online say they have the same problem
