- Issues
- [DSv4] Remove sparse-MLA q-head padding for FlashInfer >=0.6.14
- [Bug]: DeepSeek-V4 sparse-SWA decode passes flashinfer 0.6.14-only kwargs, but the pin is 0.6.13
- [Bug][XPU] compressed-tensors FP8 W8A8 (dynamic) generates garbage output on Intel Arc Pro B70 (Battlemage)
- [Bug][XPU] Mamba align-mode prefix caching crashes: "Overflow when unpacking long long" storing state.data_ptr()
- [Performance]: Marlin MoE block_size_m heuristic over-selects a large M-tile for expert-parallel decode (up to ~30% TPOT on gpt-oss)
- [Bug]: H200-NVL TP=8 FlashInfer mnnvl fused allreduce crashes at CUDA graph capture; trtllm workaround is ~34x slower than disabling fusion
- [RFC]: Confident Decoding — entropy-guided intermediate-layer logits selection
- [Bug]: Gemma-4 MTP crashes on B200 after FlashInfer selects a missing head_dim=512 TRTLLM-Gen cubin
- [Bug]: DeepSeek V4 reasoning/tool parsers produce unbalanced tags under concurrent load
- [CI Failure]: vllm chat --url : 'url' is deprecated..warning
