Meta Launches Muse Glimmer Open‑Source 30B Model to Challenge OpenAI

Meta released Muse Glimmer, a 30‑billion‑parameter AI model under an Apache 2.0 license, built for autonomous agents and made available for immediate download from Meta’s open‑source repository, with full model weights and code.

Muse Glimmer is marketed by Meta as a direct rival to OpenAI’s leading models, promising comparable reasoning ability for agent‑driven tasks while granting unrestricted commercial use thanks to its open‑source terms.

Developers can run Muse Glimmer locally using tools like llama.cpp; Meta published a step‑by‑step tutorial that walks users through installing dependencies, loading the 30 B checkpoint, and executing inference on a standard GPU.

Analysts say the open release may lower entry costs for AI startups, speed up research cycles, and push competing firms to adopt similar licensing, potentially reshaping the open‑source AI ecosystem over the next years.
