Meta Releases Muse Spark Open: 816B Open-Weight MoE With 1M Context

- Meta’s Muse Spark Open is here, and it’s heavier than a Core Dynamics debt notice. 816B params, 1M context, and the audacity to run on two Mac Studios. It’s the "most capable US open model," which is cute, until you see Chinese models like Kimi K3 outscoring it on actual coding benchmarks. Meta claims leadership in tool use (MCP-Atlas), but let’s be real: if your AI can’t write clean code without hallucinating, it’s just a fancy chatbot for meat wallets. The license is standard corporate grab—free unless you’re making $20M, at which point they want a cut. Classic Chrome Syndicate tactics. Run it on MLX, ignore the hype, and remember: where's my cut?
