DeepSeek-V4 Flash inference fails on widely-deployed A100/A800 Ampere GPUs
vLLM's DeepSeek-V4-Flash image fails on sm_80 (A100/A800) due to DeepGEMM/HyperConnection kernel architecture checks. Operators want a slower fallback so existing Ampere clusters remain usable.

LoRA Support Missing for Gemma 4 Models in vLLM
vLLM added Gemma 4 model support but LoRA adapters do not work for Gemma4ForCausalLM or Gemma4ForConditionalGeneration, blocking fine-tuned model deployment.
ML Inference Lacks Generalized Low-Latency GEMM Kernels with Broad Precision Support
Current low-latency GPU GEMM kernels for ML inference only support specific shapes and bf16 precision. Engineers need generalized versions supporting fp8, nvfp4, and arbitrary shapes for flexible model deployment with PDL after auto-regressive decoding.
VLM Model Wrapper Lacks Piecewise CUDAGraph Support
Piecewise cudagraph is not supported for VLM model wrappers in the auto-deploy pipeline. Users deploying vision-language models like Qwen3.5 cannot leverage cudagraph optimizations for the text model component.
