Muse Spark 1.2: Meta's August 2026 coding-model update
This August 2026 launch snapshot covers Muse Spark 1.2; Muse Spark 1.3 is the newer model available in the current catalog.
What changed
- Meta's announcement describes expanded coding-task training and joint training work with Muse Code; these are vendor-reported development claims.
- Meta's Model API pricing page describes standard and contributor tiers with different data-use terms; check the live terms and account eligibility before sending data.
Best fit
- Long-running coding agents
- Repository-scale tasks
- Meta Model API users
What to be careful about
- This is a historical 1.2 launch entry; Muse Spark 1.3 is newer. Muse Code's current rollout and productivity fit should be checked separately.
- Contributor-tier eligibility and data use are account/contract dependent; inspect the current first-party terms before use.
Dataset snapshot: Muse Spark 1.2 is also represented in the checked comparison dataset. Prices and benchmark figures carry their own field dates.
