pytorch#2573) ## Summary `FP8GroupedMMConfig` was a temporary backward-compatibility alias in torchao that has been removed in pytorch/ao#4069. This PR updates torchtitan to use the canonical `Float8TrainingOpConfig` name directly. ## Change One-line rename in `torchtitan/components/quantization/float8.py`: - `FP8GroupedMMConfig` → `Float8TrainingOpConfig` (import + usage) ## Test plan - No behavior change — `FP8GroupedMMConfig` was an alias for `Float8TrainingOpConfig` with identical defaults. - Existing MoE FP8 training tests cover this code path. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Li <lizli102@ctr2-alola-ctrl-01.amd.com> Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com>
