Pull request overview
This PR updates the sequential (per-expert) MoE forward passes for Llama-4 and GPT-OSS to skip experts that receive no tokens, reducing unnecessary expert compute during calibration/quantization flows.
Changes:
- Update Llama-4 MoE forward to only run experts with non-zero routing mass.
- Update GPT-OSS MoE forward to only run experts that have any tokens routed to them.
