Thanks for your great work! I’ve successfully reproduced the results on Qwen3-8B using your SFT settings via LLaMa-Factory, and the performance is indeed impressive. However, I noticed a specific parameter in the configuration: max_grad_norm is set to 2e-5. This is quite unusual for LLM fine-tuning, where values like 1.0 or 0.5 are standard. Given that such a small threshold significantly clips the gradients, I’m curious about the intuition behind this choice: How does this extremely low threshold impact the convergence speed and final model performance in your experiments? What's your motivation behind it?
