Qwen3-8B-Chemistry-GRPO-TR

This repository contains the Qwen3-8B chemistry GRPO batch-size-32 run. The repository name uses the project GRPO-TR naming convention, but the actual training method for this checkpoint is GRPO.

The repository root contains the best validation checkpoint, selected by validation mean@16. checkpoints/last/ contains the final checkpoint.
