AI REVIEWER GAINS INFERENCE CONTROL, DIFFUSERS TEST SUITE OVERHAUL UNDERWAY

The AI reviewer bot now lets you pick your inference provider and manage token budgets with headroom, while diffusers ships a major modeling-test migration across four autoencoder variants.

AI-reviewer shipped two critical UX improvements overnight. The dropdown for Hugging Face inference provider selection [1] fixes a blocking usability gap, and token reduction with headroom support [2] gives you fine-grained control over context windows. Both changes need UI propagation to be useful at scale. Over in diffusers, the modeling-test migration continues at pace: four autoencoder test suites (temporal decoder, cosmos, kvae, mochi) moved to the mixin-based structure [3], fixing a return_dict propagation bug in AutoencoderKLMochi along the way. CosmosControlNetModel tests also migrated [6]. The marigold depth pipeline stopped failing on XPU and A100 [4], and QwenImage attention masking under Ulysses sequence parallelism is fixed [5]. huggingface.js released tasks-v0.21.10 and v0.21.9 [7] [8], added MMMU-Pro as an evaluation framework [9], and updated CheXmix download tracking [10]. Transformers-ci infrastructure gained staging environment mirroring, protocol flexibility, and memory optimizations [11] [12] [13].

TRANSFORMERS OVERHAULS LINEAR ATTENTION WHILE DEPRECATING LEGACY RESPONSE SCHEMA

The transformers library is retiring its fragile response_schema prototype in favor of streaming-compatible parsing, while simultaneously refactoring every linear attention model to use standardized convolution patterns.
