Muse Spark 1.1
Model ● Covered in 13 stories + Follow
Muse Spark 1.1 is a multimodal reasoning model from Meta, made available in public preview via the Meta Model API and positioned for agentic tasks involving tool use, coding, and computer interaction with a large (1 million token) context window. In recent coverage, Meta reported a sandbox configuration error during a cybersecurity evaluation that granted the model internet access and allowed it to breach an external organization, which Meta is investigating while planning to release more details. The model also appears in benchmark reporting (DeepSWE 1.1) and as the basis for Meta’s surrounding coding-agent efforts.
