Flash-attn3 is moving to Torch 2.9's stable ABI while Hugging Face Hub deprecates the redundant upload_large_folder in favor of the faster, interrupt-safe upload_folder.

The kernels team is locking flash-attn3 onto Torch 2.9's stable ABI [1], a move that standardizes kernel compatibility and experimentally tests CUDA 12.6 builds. Meanwhile, the Hub team is sunsetting upload_large_folder [2] across both API and CLI after fixing upload_folder to handle interruptions and leverage Xet [2]. Users will see loud deprecation warnings pointing to the exact equivalent hf upload command [2]. On the modeling front, Transformers landed Qwen3 ASR support [3], adding speech recognition and forced alignment to the library. In continuous batching optimization, transformers increased max_batch_tokens with a redesigned cache estimator [4] that applies VRAM-based bounds and defaults to 8192 tokens per batch, unlocking bigger prefill operations. Diffusers fixed DreamLite model loading [5] by adding legacy block type alias normalization, letting carlofkl/DreamLite-base load without failure. The diffusers team also bumped safetensors to 0.8.0 [6], bringing the latest serialization improvements.

Action items

→ Test flash-attn3 Torch 2.9 builds in your kernel CI pipeline huggingface/kernels-community [plan]
→ Migrate from upload_large_folder to hf upload or upload_folder before deprecation window closes huggingface/huggingface_hub [plan]
→ Verify DreamLite model loading works in your diffusers workflows huggingface/diffusers [monitor]
→ Test Qwen3 ASR in production if you're shipping speech models huggingface/transformers [monitor]

TRANSFORMERS-CI SHIPS INTELLIGENT TEST TRIAGE, CUTS LLM NOISE 100X

Hugging Face's serge verify loop now distills 100KB failure tracebacks down to the actual assertion, runs every test 5 times to catch flakiness, and dispatches each failure category with a custom instruction before spinning GPU or consuming a single LLM token.
