Are you launching your experiment with the deepspeed launcher, MPI, or something else?

Docker context
Are you using a specific docker image that you can share?

Additional context
Add any other context about the problem here.

Start by reproducing the reported Firefly SFT setup with gradient_clip set to auto and max_grad_norm set to 1.0, then run ds_report to capture the missing environment details. Compare behavior across DeepSpeed 0.14.5, 0.15.3, and 0.15.4; done means max_grad_norm demonstrably affects gradient clipping under the reported launcher and training configuration.
