Pricing Details

MetaSame weights and context window as muse-spark-1-2, priced 12.5x lower on input and 21.25x lower on output in exchange for permission to train future Meta models on your prompts and completions. Cached input $0.002/1M, a 75x discount against the standard tier's $0.15, which makes a cached token 2% of a fresh one here against 12% on standard. Rate limits are much tighter: 60 RPM / 2.1M TPM per team plus a separate 600-per-minute background submission cap, against 3,000 RPM / 4M TPM on standard. Requests are cut 50x while tokens are cut only 1.9x, implying ~35,000 tokens per request against ~1,333 on standard. Not a production tier at 60 RPM. Note the rate is not a floor: Poolside's Laguna S 2.1 sells at the identical $0.10/$0.20 across several hosts, with the same 1,048,576 context on the paid BF16 endpoint and no data condition (OpenRouter has since moved to $0.09/$0.18). Meta has not published the exact scope of the contributor grant (training only, or also evaluation, red-teaming and analytics). Web search grounding pricing on this tier is undocumented.
