“Built with Muse Spark Open”
Meta launched Muse Spark Open, an 816B-total/42B-active MoE model that scores 39 on Artificial Analysis's Intelligence Index—the highest for any US open-weights model. The model supports text, image, video, and audio inputs with 1M context, and fits on 4 Blackwell Ultra GPUs or 8 H200s at roughly $1.25/$4.25 per M tokens. Despite leading on Omniscience benchmarks, it ranks last among top-9 open models on agentic evals, highlighting a gap as agentic workloads grow in importance.
