# FINER-SQL-3B-BIRD

Trained from [`griffith-bigdata/Qwen-2.5-Coder-3B-SQL-Writer`](https://huggingface.co/griffith-bigdata/Qwen-2.5-Coder-3B-SQL-Writer) using GRPO with two dense rewards from the FINER-SQL paper:

🧠 Memory Reward — aligns reasoning with verified traces  
⚙️ Atomic Reward — measures operation-level SQL overlap  

✅ 67.5% EX on BIRD when training only on BIRD train dataset; infer on a single 12-24 GB GPU
