Muse Spark is a large language model (LLM) developed by Meta through its Meta Superintelligence Labs (MSL). It was introduced in April 2026 and launched as Muse Spark 1.1 on July 9, 2026. It is the first model in Meta's Muse family and is designed for multimodal reasoning, coding, and AI-assisted software development. It also powers Meta AI across Meta's products and services. It can handle a million tokens of context.[1][2][3]
Mark Zuckerberg has stated that Meta will release Muse Spark 1.2 as an open-weight model.[4] Meta released a smaller open-weight large language model, Muse Glimmer, on August 10, 2026.
Muse Code
Meta released Muse Code, a terminal-based coding agent, alongside Muse Spark 1.2 on August 5, 2026. Powered by the model, it can write and debug code, complete longer software development tasks, and run multiple sub-agents concurrently.[5] Muse Spark 1.2 was also made available through the Meta Model API and OpenRouter.[6][7] A lower-priced contributor tier allows Meta to retain submitted data to improve its products, while data submitted through the higher-priced standard tier is not retained for that purpose.[8]
Muse Glimmer
Muse Glimmer is an open-weight multimodal large language model developed by Meta released on August 10, 2026. The 30-billion-parameter causal language mode combines a large language model with a dedicated perception encoder and supports both natural language and visual inputs. It was designed for local agentic and coding workloads, and can be run entirely offline on a single 24 GB consumer GPU.[9] The model weights are distributed under the Apache License 2.0.[10][11][12]
