Meta released Muse Glimmer on Monday, a 30-billion-parameter model built for agent work that fits on a laptop. The company published the model's weights - the trained numbers that make up the model itself, meaning anyone can download it and run it on their own machine - on the model repository Hugging Face, under an Apache 2.0 license that is genuinely permissive, without the usage restrictions Meta attached to its Llama releases.

Google has Gemma, Alibaba has Qwen, Mistral and DeepSeek both ship small open models. Meta is arriving late to a category it arguably created and then abandoned.
What It Is
Glimmer was built from Muse Spark, Meta's frontier model, using a technique called distillation: you train the small model on the big model's output until it learns to imitate what the larger system already knows.
Then there's the problem of making it fit. A 30-billion-parameter model at full precision needs more than 55GB of memory, which no consumer graphics card has. Meta compressed the numbers that make up the model down to roughly a quarter of their usual precision, shrinking it to under 20GB - small enough to leave room for everything else the model needs running alongside it inside a 24GB or 32GB card. The company says the compression costs little or nothing on the tasks that matter.
