Continue the latest directive: try out PyTorch/diffusers optimizations, review the linked PyTorch Inductor config, Diffusers optimization docs, and related articles/repos, using 5 Opus subagents unforked to group the materials and identify leverageable improvements. The latest tool call already completed: it fetched/rebased onto remote, ran `tests/test_diffusion_speed.py`, and appears to have succeeded; do not rerun it. Next action is to inspect the completed command output/truncated state if available, then push the rebased `diffusion-phase7-perf` branch or otherwise continue the PR update flow implied by “Remote advanced… rebase and push.”
