🤗 MOSS-VL-Realtime is now open source on @huggingface . The 11B model family supports text, single and multiple images, single and multiple videos, and interleaved visual-text inputs in Chinese and English.@MosiAI_Official Highlights: 🏗️ Cross-Attention architecture separating visual encoding from language reasoning 🧭 XRoPE for unified temporal-spatial positioning 🧩 Unified conversation templates for offline, streaming, and real-time interaction 🧠 256K-token context window 📜 Apache-2.0 license MOSS-VL-Realtime continues processing new frames while generating a response, allowing it to revise or interrupt that response as the scene evolves—or remain silent when more evidence is needed.

Serving GLM5.2 NVFP4 Agentic Workload with SGLang: How We Reached 500 TPS on 8xB300 at bs=1 In this deep dive, we explain how SGLang reaches 500+ tok/s/user at bs=1 on 8xB300, with 18 to 34% higher single-user interactivity within two weeks since day-0, and 6 to 11% better peak throughput at high concurrency, benchmarked on a real multi-turn agentic coding workload. Our new TopK-V2 kernel is 2.33x faster at 80K ISL, scaling to 10.17x at 1M ISL, keeping interactivity essentially flat out to 1M tokens. Part of the story is the architecture itself. GLM-5.2 applies IndexShare to its DSA layers and ships a stronger MTP head reusing IndexShare and KVShare. The rest comes from our serving optimizations. Special thanks to @NVIDIAAI for the help in day-0 support of GLM-5.2 NVFP4, and to @Zai_org for IndexShare in SGLang!

Great to see mini sglang being used in FastAFD by Hao AI Lab. Really nice work on NVL72! It's awesome to see it extended to this scale with such strong results. 🚀

🚀 Can Attention-FFN Disaggregation still win on the newest rack-scale GPU systems? We built FastAFD, an open-source AFD runtime for GB200 NVL72: 72 Blackwell GPUs in one NVLink domain. It improves per-GPU decode throughput by 1.35-1.45×. 🧵 Code: github.com/hao-ai-lab/Fas… Blog: haoailab.com/blogs/fastafd/




💡 Continuous software innovation is the force multiplier behind AI infrastructure — compounding inference performance, lowering cost per token, and increasing long-term value with every optimization. Open source accelerates this advantage. Leading AI frameworks like @PyTorch and inference engines such as @sgl_project and @vllm_project are built natively on NVIDIA CUDA, enabling research breakthroughs and software optimizations to unlock great performance on NVIDIA GPUs from day zero.

Sglang compatible 2.7bpw in vram with configurable offloading to provide more quality recovery at the cost of speed and ddr or nvme memory. Inspired by vllm-moet. Benchmarking nice, very very fast. github.com/0xSero/sglang-…
