Pricing Details
MetaSame weights and context window as muse-spark-1-3, launched the same day (OpenRouter listing created 2026-09-02 20:38 UTC, 53 minutes after the standard SKU). Model ID muse-spark-1.3-contributor. SAME RATE CARD AS THE 1.2 CONTRIBUTOR TIER TO THE CENT: $0.10 input, $0.20 output, $0.002 cached input, 12.5x / 21.25x / 75x below standard; web search grounding $2.50 per 1,000 queries is now documented for this tier too. Now on Meta's own pricing page (ai.developer.meta.com/docs/pricing-rate-limits, verified 2026-09-14), which defines the tier as 'heavily discounted token pricing in exchange for permission to use your prompts and completions to train future Meta models'; the model page's one-line version is 'Used to improve our products' against the standard tier's 'Not used to improve our products', and OpenRouter's listing says 'Prompts and outputs may be used to improve Meta's products'. 'Improve our products' is broader than 'train future Meta models', so the grant's scope beyond training is still not pinned down. RATE LIMITS LOOSENED against the 60 RPM / 2.1M TPM reported at the 1.2 contributor launch: Meta's page now lists 100 RPM / 3M TPM per team for the contributor tier, plus the shared 600-per-minute background submission cap, against 3,000 RPM / 4M TPM on standard. Still not a production tier at 100 RPM. OpenRouter (meta/muse-spark-1.3-contributor) and LiteLLM (meta/muse-spark-1.3-contributor) carry the identical $0.10/$0.20/$0.002 and 1,048,576 context. Max output not on Meta's page (LiteLLM 131,072; OpenRouter 943,718); 16,384 stored for parity with the 1.2 entries. Poolside's Laguna S 2.1 still sells at $0.10/$0.20 on several hosts with no data condition, so the discount buys nothing you cannot get elsewhere without the training grant.
