Muse
Meta's current line, built for long multi-agent runs.
Muse is what Meta Superintelligence Labs ships now, and the family to look at rather than Llama if you want Meta's recent work. The Spark models are multimodal reasoning models for long-running agentic and multi-agent workflows — they read text, images, video, audio and files with a million-token context, and are built to hold onto what they learned early in a long task. Each Spark release also has a cheaper "Contributor" tier meant for experimenting rather than production. Glimmer 30B is the odd one out and the interesting one: open weights, distilled from Spark, small enough to run autonomous agents on ordinary hardware.
