Fine-tuning a 350M model for better structured outputs in 100 GRPO steps

KEY POINTS

1. Hugging Face published a post describing a process to fine-tune a 350M-parameter model aimed at producing better structured outputs using 100 GRPO steps.
2. The item outlines the approach and workflow for applying this fine-tuning technique.
3. This matters because it documents a potentially efficient recipe for improving structured outputs from a relatively small model, which could help practitioners iterate faster and reduce compute costs.
