@MekkCyber this one has been waiting since 2025-12-19 (overlap with #46324 + quantizer refactor #49548). Still planned, or should we close it?

[ArthurZucker]

Hi! This overlaps with #46324, which makes cls(config) / from_config honor quantization_config through a generic per-quantizer opt-in, with FP8 as the first user. All three files here also conflict with main now. Should we consolidate on #46324 and close this one, or is there something here (e.g. the FP8 weight init) that should be carried over?

[MekkCyber]

@ArthurZucker feel free to close it, the logic in #46324 should be enough, Thanks for the notice
