Meta Muse Spark 1.2 Meta Muse Spark 1.2
Meta Muse Spark 1.2 is a multimodal reasoning model optimized for complex, long-horizon coding and agentic tasks. It features a 1-million-token context window and is co-trained with the Muse Code terminal agent to enhance tool use and task reliability.
Launched August 5, 2026, alongside the Muse Code terminal agent, featuring improved coding accuracy and better multi-agent orchestration compared to the 1.1 release.
As of
- 1 million token context window
- Persistent asynchronous background agents
- Worktree-isolated sub-agent fan-out
- Replay-exact, restart-safe local event logging
- Multimodal input support (text, image, video, PDF)
High-volume, cost-sensitive coding projects and long-running autonomous software engineering tasks that benefit from persistent agent sessions.
Proprietary or sensitive codebases where data privacy is paramount, as the default 'Contributor' pricing tier uses your input for training.
Standard tier: $1.25/M input tokens, $4.25/M output tokens; Contributor tier: $0.10/M input tokens, $0.20/M output tokens. Contributor tier allows Meta to use your data for model training.
A powerful, competitively priced foundation for agentic coding that trades peak benchmark performance for significant cost advantages, provided you are comfortable with the data-sharing terms of the contributor tier.
