Two M5 Ultra Mac Studios with 1TB combined memory run the model via Apple’s updated MLX toolkit, and Meta says it shipped iOS app fixes and edited video in DaVinci Resolve without cloud.\n\nOn the Artificial Analysis Intelligence Index, the model sits at 39, ahead of West open-weight models but behind China’s GLM 5.3 (45), Kimi K3 (44) and Qwen3.8 (40). Spark Open matches or tops open rivals on multimodal and knowledge tasks, though Chinese models still code better. It is the third major Western open launch this month after Reflection AI’s Beam and Mistral’s 1T-parameter Le Chonk, whose weights arrive Oct. 27.\n\nMeta’s move signals a return to open model strategy after its earlier shift to closed Llama models. The release gives U.S. developers a large open-weight model that can run locally, potentially reducing cloud dependence, and challenges China’s dominance in the open-model race.","keyPoints":["Meta releases 816B-parameter Muse Spark Open, an open-weight multimodal model","Two M5 Ultra Mac Studios with 1TB memory run Spark Open via Apple MLX toolkit","Model ranks 39 on Intelligence Index, ahead of West open models but behind China’s GLM 5.3, Kimi K3, Qwen3.8"],"whyItMatters":"The release gives U.S. developers a large open-weight model that can run locally, reducing cloud reliance.
