[dependabot]

Bumps sglang from 0.5.2 to 0.5.9.

Release notes

Sourced from sglang's releases.

v0.5.9

Highlights

• LoRA Weight Loading Overlap with Computation: Overlap LoRA weight loading with computation during inference, reducing TTFT by ~78% and TPOT by ~34.88% on large adaptors: #15512

• TRT-LLM NSA Kernel Integration for DeepSeek V3.2: Integrate TRT-LLM DSA kernels for Native Sparse Attention, boosting DeepSeek V3.2 performance by 3x-5x on Blackwell platforms with trtllm for both --nsa-prefill-backend and --nsa-decode-backend (with minor accuracy drop): #16758, #17662, #18389

• Flashinfer All-to-All MoE Dispatcher: Add the Flashinfer all-to-all MoE dispatcher for efficient expert parallelism communication, enabling optimized routing in MoE models: #14668

• FA4 (FP4 Attention) Support for Multimodal Encoder: Introduce FP4 attention backend and variable-length attention function for multimodal encoders, enabling lower-precision inference for vision-language models: #13539

• Anthropic Compatible API Endpoint: Add native Anthropic API compatibility to SGLang, allowing direct integration with tools and clients built for the Anthropic API format: #18630

• SGLang-Diffusion Advanced Optimizations: Production-ready improvements including token-level sequence sharding, parallel VAE decoding, fused kernels, Nunchaku and FP8 support, and multiple new models in the ComfyUI plugin: blog

• Spec V2 Critical bug fix: Fix out-of-index bug caused by torch garbage collection in speculative decoding v2, improving reliability of speculative verification: #18958

• Deploying DeepSeek on GB300 NVL72: Optimization work for long-context inference using prefill-decode disaggregation and other SGLang features on NVIDIA's latest GB300 platform: blog

• Bump AITER version to 0.1.10.post3: Support FP8 Prefill/Decode/KV Cache

• Commit-to-Version Lookup in docs.sglang.io: Easily find the earliest official version that includes a given PR or commit, streamlining release tracking for users and developers: #18450, link

New Model Support

• Kimi-K2.5: #17789, cookbook
• GLM-5: cookbook (still requires a custom docker for transformers upgrade, will follow up with a rc release since transformers upgrade is risky)
• Qwen 3.5: #18489, #18926, #18937, cookbook
• MiniMax 2.5: cookbook
• Ernie4.5-VL: #15679
• Step3-VL: #17513
• Step-3.5-Flash: #18084, cookbook
• LLaDA 2.1: cookbook
• Ring 2.5 1T / Ling 2.5 1T: #18598, cookbook, cookbook
• MOVA (Diffusion): #17704
• GLM-OCR: #17582, cookbook
• DeepSeek-OCR-2: #17897

SGLang-Diffusion

• Support multiple new models in ComfyUI Plugin
• Parallel Folding and Parallel VAE Decoding for faster image/video generation
• Nunchaku and FP8 support for diffusion models
• Sequence Sharding (token-level) replacing Frame Sharding for improved efficiency
• LTX-2 support: #17495, #17496
• MOVA model support: #17704
• Cache-DiT optimizations and fused kernel improvements
• Numerous bug fixes and refactors across the diffusion pipeline

Performance

• Integrate TRT-LLM NSA kernels with up to 3-5x speedup on Blackwell: #16758, #17662, #18389
