- Move cudnn_deterministic to per-spec train_args instead of hardcoding it for all models. cuBLAS deterministic mode triggers internal errors on Gemma-based models (pi0, pi05) during backward pass. - Enable use_amp=true for pi0, pi0_fast, and pi05 to reduce memory footprint from fp32 (~16GB weights alone) to bf16, fitting within 22GB GPU budget with room for activations and gradients. - Small models (act, diffusion, multi_task_dit) still use deterministic mode for reproducible profiling results.
