Meta released Muse Glimmer, a 30B open-weight model under an Apache 2.0 license, optimized for end-to-end agentic task completion with strong benchmark results on SWE-Bench, DeepSearch QA, and MCP-Atlas. Simon Willison tested the vision-capable model locally via LM Studio, demonstrating its ability to navigate codebases and handle multi-step workflows with reliable tool use.
Background
Meta has re-entered the open weights space with Muse Glimmer, following earlier Llama licenses that many found restrictive. The model targets local deployment on consumer hardware with 32GB+ RAM, competing in the growing market of capable open-source coding and agentic AI models.
