Meta released Muse Glimmer, a 30-billion-parameter open-weight model licensed under Apache 2.0 that is optimized to run on a single GPU for local, agentic workflows and multi-step reasoning. The company also announced it will make its Muse Spark 1.2 coding model open source, a shift from its earlier paid-only release alongside the Muse Code agent. Meta’s pivot back toward open models reflects rising inference costs and enterprise demand for local model control, positioning the company against both proprietary foundation model providers and Chinese open-weight rivals.
