- Issues
- [Bug]: Tiered KV offload promotes every waiting request (which fills primary DRAM pool)
- [Bug]: Cross-node Pipeline Parallelism (PP) fails with "invalid device ordinal" at PyNccl warmup on ROCm (AMD RDNA4 / R9700), reproducible on first inference even after context-corruption workaround
- [Bug]: SpeculativeConfig method="draft_model" cannot load mixed-precision compressed-tensors checkpoints (config_groups)
- Support Voxtral audio generation in the Transformers backend
- fix(responses): reject code_interpreter tool call missing "code" field
- kernels: fused silu_and_mul + dynamic per-token FP8 quantization
- [Bug] DeepSeek-V4 on SM12x: NaN MQA logits drive top_k_per_row_prefill to emit uninitialized smem as indices -> illegal memory access
- [Bug]: [Regression] Assertion res == CUresult::CUDA_SUCCESS failed in FlashMLA (phase1.cuh) for DeepSeek-V4 on v0.26.0 (Works in v0.25.0)
- [ROCm][Perf] Speed up single-group MoE routing
