PR Summary
Migrates FP8 quantization from deprecated float8_experimental to torchao library in the infinity embedding engine.
torchaodependency inpyproject.tomlshould be moved from dev dependencies to main optional dependencies since it's core FP8 functionality- Version constraint of
torchao>=0.7.0needs stricter upper bound to ensure PyTorch 2.2.1+ compatibility - Missing test coverage for new FP8 quantization implementation
- Documentation updates needed in docs folder as per unchecked items in PR checklist
