Pricing Details

MetaLaunched August 5, 2026 alongside Muse Code, Meta's terminal coding agent. Standard tier rates are unchanged from Muse Spark 1.1 to the cent; the entire pricing change in this release is the separate contributor SKU (see muse-spark-1-2-contributor). Cached input $0.15/1M (88% off). Web search grounding $2.50 per 1,000 queries. Rate limits 3,000 RPM / 4M TPM per team. Meta states it does not train on prompts or completions submitted at this tier. As with 1.1, Meta published no prices on its own announcement or developer product page: all figures come from the launch email and Model API rate card, corroborated to the cent across Vorp Labs, Implicator, Layer3 Labs and Vercel AI Gateway. Benchmarks are vendor-run inside Meta's own Muse Code harness and unlabelled on Meta's charts: Terminal-Bench 2.1 82.9, DeepSWE v1.1 59.3, Meta internal bench 70.6. Independent trackers disagree on the resulting ordering. Estimated tokens (different tokenizer).
