DIFFUSERS SHIPS TEST-BY-COMMENT BOT, TAMPS DOWN INFERENCE.JS AUDIO BUGS

Diffusers just handed developers a GPU-friendly shortcut: run tests from PR comments instead of waiting for full CI cycles, while inference.js fixes a silent failure that broke browser audio uploads to fal-ai.

The diffusers team shipped a comment-bot workflow [1] that triggers GPU-intensive tests on demand within pull requests, cutting the friction of manual test runs when you need real hardware validation. This lands alongside a major refactor wave across transformers tests [2] and unet variants [2], tightening up test patterns across the codebase. Over in TRL, the team axed redundant `.contiguous()` calls [3] and cleaned up silently-ignored config fields [4] that were cluttering GOLD and Distillation configs, moves that reduce confusion and surface real deprecations. The inference.js release [5] patches a critical bug where fal-ai's ASR rejected browser webm and wav uploads due to MIME type labeling [6], a fix that matters for anyone shipping voice features. LeRobot pushed a bimanual robot refactor [7] that finally unifies drifted implementations across followers and leaders, plus a video-pipeline fix [8] that stops image features from getting accidentally deleted when video encoding isn't used.
