Meta open-sources Muse Spark Open agent model with day-0 TPU support in SGLang
BanghuaZ · x · 2026-10-16
Meta, RadixArk and the SGLang team shipped production-ready support for Muse Spark Open, an open model built to plan, act and use a computer across agentic tasks.
Key technical points:
- Meta's custom auto-tunable Helion kernels deliver 1.03–3.95× kernel-level speedups on NVIDIA and AMD GPUs
- Day-0 support on Google TPUs via SGLang-TorchTPU, a first
- Ultra-responsive inference with NVFP4 MegaMoE and sequence parallelism, plus a DFlash2 draft model for agentic and coding tasks
- Fine-tuning for specialized use cases via Miles
Together it outlines a fully open stack for building powerful personal AI agents.
