[dependabot]

Bumps sglang from 0.5.2 to 0.5.12.

Release notes

Sourced from sglang's releases.

v0.5.12

Highlights

• DeepSeek V4 support: Full inference path for DeepSeek-V4 (#23882), including:

  Day-0 Features: #23882

  • Parallelism: Tensor Parallelism/Expert Parallelism/Context Parallelism/Data Parallel Attention
  • Hardware: Nvidia B300/B200/H200/H100/GB200/GB300, AMD MI35X
  • Prefill-Decode Disaggregation
  • HiSparse for offloading inactive KV cache to CPU memory
  • Reasoning parser and Tool Call Parser
  • DeepGemm and FlashMLA kernels for DeepSeek V4, including MegaMoE

  Post-Day-0 additions:

  • HiCache for DeepSeek V4 under unified Radix Tree [UnifiedTree]: #24691
  • W4A4 MegaMoE kernels — faster speed with negligible accuracy drop: #25052
  • Marlin/FlashInfer W4A8 MoE kernels on Hopper: #24816 #24986
  • Faster V2 fused compression kernels: #24890
  • TP16 support on H100/H20: #24949
  • Fused SiLU+clamp+FP8 quant kernel: #24897
  • Optimized MHC + DeepGemm pipeline (fused norm, fused hc_head): #24775
  • Non-standard chat template support for DSv4: #23915
  • Multi-detokenizer support: #24944
  • Pipeline Parallelism + PD support for DeepSeek-V4: #24700
  • A unified docker tag lmsysorg/sglang:v0.5.12 for all Nvidia GPUs

  See the LMSYS blog and the DeepSeek-V4 cookbook for more details.

• TokenSpeed MLA attention backend (Blackwell, FP8 KV cache): New MLA prefill/decode kernels integrated as an attention backend on SM100, with FP8 KV cache support for low-latency MLA serving: #24925

• DSv3.2 / GLM-5 FP4 low-latency perf: PDL enabled across DSv3.2 / GLM-5 kernels, torch.mm for the DeepSeek V3.2 indexer GEMM, and a reland of the Cute-DSL FP4 dense GEMM — materially trimming low-latency overheads on FP4 paths: #23965, #23856, #23590, #25311

• New Model Support: DeepSeek V4 #23882, Intern-S2-Preview #24875, MiniCPM-V 4.6 #24855, Laguna-XS.2 #24204, Ring-2.6-1T #25360, and Gemma 4 MTP #24436 — with cookbook recipes for tuned deployment commands. See docs.sglang.io/cookbook

• HiCache + UnifiedRadixTree: HiCache framework support for UnifiedRadixTree (with SWA), HiCache for DeepSeek V4, SSD offload through Mooncake store, and stability fixes across cascade eviction, tombstone replay, and partial-match paths: #23316, #23391, #24691, #24277, #24943, #24972, #25068, #25277

• Speculative Decoding V2 maturation: Adaptive Spec V2, EAGLE-3 SWA + newer drafters, Kimi K2.5 EAGLE-3 MLA, Gemma 3/4 + EAGLE-3, and an extensive naming / shape-handling refactor across draft-extend paths: #23336, #24663, #24664, #24826, #23976, #24859

• CUDA 13 DeepEP migration: Gateway DeepEP source swapped from a community fork to deepseek-ai/DeepEP@hybrid-ep so DeepEP builds and runs cleanly on the CUDA 13 default; FlashInfer pinned at 0.6.11.post1 alongside a gpt-oss triton-kernel fix: #25113
