Super excited to support SGLang Summit 2026! During the summit, our Chief Scientist, Dong Li, will give a talk about MoE Optimization on SGLang-Trainium. In this talk, he will cover our efforts to add new MoE models and optimize their inference latency with SGLang-Trainium. Come join the talk or find us at our booth during the summit!

i'll be speaking at sglang summit in SF, nov 12-13! going to walk through the post-training and inference work we’ve been doing at Decagon, and how we scaled out our RL training pipelines to ~1T param models if you’re going, let’s say hi! sglang.io/summit @sgl_project

Thanks to the amazing team at @sgl_project for working closely with us on optimizing Beam both for 3P users and also for our Beam's production API. Fun fact, Jimmy from SGLang team was working with us in our office till late last night wrapping up the last pieces of this launch. This is the sort of collaboration that has lead us to have such a broad release. 🤝
SGLang powers Beam’s production API, with day-0 support now available to everyone! Built for software engineering and long-horizon agents, Beam delivers frontier-level inference efficiency with more intelligence per token.

Beam is now available across platforms, with open weights under the Apache 2.0 license - in collaboration with an ecosystem of 40+ partners. We're releasing: - Weights, tokenizer, and reference implementation - BF16, FP8 and NVFP4 weights and a DFlash2 drafter - The open source harness we built and trained Beam on: Mirror CLI Weights and model card on Hugging Face: huggingface.co/reflection

Our team worked with @reflection_ai to get Beam running on SGLang, and it now serves their production API. Beam is also supported in Miles for RL training. Congrats to the Reflection team on the launch!

Congrats to @reflection_ai on launching Beam! SGLang serves it in production at Reflection, and starting today anyone can run it on SGLang too. Thanks to the Reflection engineers who worked with the SGLang community to get it ready for launch!

Muse Spark Open is built to plan, act, and use computer across agentic tasks for life and work. You can now build a powerful personal AI agent with an open stack, and SGLang to make it: - Ultra-responsive with NVFP4 MegaMoE and sequence parallelism - Faster for agentic and coding tasks with our DFlash2 draft model - Customizable for specialized use cases via fine-tuning with Miles We’re incredibly proud to have made this possible with @AIatMeta, @NVIDIAAI, @AIatAMD, @intel, and @radixark!
Today we’re releasing Muse Spark Open, the most capable US open-weight model to date. Built for coding and agentic work, it excels at long-horizon tasks, complex software engineering, and multi-step reasoning. Key Model Specs: → 816B total / 42B active parameters → 1M token context window → Natively multimodal across text, image, video, audio

SGLang has Day-0 support for Ling-3.1-flash from @AntLingAGI! A 560B MoE hybrid reasoning model, 25B active, 1M context, built for real work: it turns a rough brief into a page, mobile UI, or interactive prototype. ✅ MXFP4 + block-FP8 quantization cuts weights from ~534GB to ~292GB, fitting on 4 Hopper GPUs ✅ Strong on real-world agent, office, and coding tasks, including GDPVal-AA, FrontierSWE, and Terminal-Bench 4.0. Get started with SGLang:
Ling-3.1-flash is now open source: ~560B total parameters, ~25B active per token and up to 1M context. Built for real work, it can turn a rough brief into a page, mobile UI or interactive prototype teams can review and refine. See the demo.
