Muse Glimmer
An open-weight on-device agent model released by Meta with 30 billion parameters, distilled from the Muse Spark large model. Designed for on-device agent workflows, it supports efficient execution on NVIDIA hardware via ExecuTorch.
Core Facts
Muse Spark can be used as a backend via OpenCode Go.
Running Muse Glimmer at full precision requires 55 GB of VRAM, which is compressed to under 20 GB via 4-bit quantization, allowing it to run on consumer-grade GPUs with 24 GB of VRAM.
Muse Glimmer 30B has 29.6 billion parameters and is a dense model.
Timeline (last 90 days)
Meta released an open-weight model named Muse Glimmer
In a C++ wireless skateboarding game test, Muse Glimmer's attempt to fix a compilation error caused the entire system to crash completely
In actual testing under agentic tasks, the performance of this quantized version of Muse Glimmer drops by only 0.2%, and only 1% when compressed to the 24GB version
On an RTX 5090, Muse Glimmer runs at 75 tokens/second without speculative decoding, and reaches 233 tokens/second when paired with a speculative decoding model
Muse Glimmer has a context length of 131,072 (approximately 130,000 tokens) and comes with an extendable token marker
Muse Glimmer has multimodal capabilities, with a built-in vision encoder that can accept both text and image inputs simultaneously
Muse Glimmer adopts the Apache 2.0 license
Muse Glimmer can run on a single consumer-grade GPU with 24GB VRAM or a Mac equipped with sufficient unified memory
Muse Spark can be used as a backend via OpenCode Go.
Meta released Muse Spark in April (its first frontier model without releasing weights), and four months later released Muse Glimmer (30 billion parameters, Apache license, distilled).
