Meta just released weights for Muse Spark Open, and it’s now available on Modal Auto Endpoints.
Muse Spark Open is built for agentic coding and long-horizon tasks, with native multimodal understanding and a 1M-token context window. It supports writing and debugging code, multi-step planning, sequential tool use, and failure recovery across extended workflows.
In Meta’s evaluations, Muse Spark Open scores 76.4 on Terminal-Bench 2.1 using the Terminus 2 agent and 60 on DeepSWE 1.1 using Meta’s preferred harness, with xhigh reasoning effort. See the released model card for the benchmark results and evaluation settings.
