What rate, concurrency and spend limits do the services publish, and how should a batch of shots be scheduled against them?

Partially verified: the curator re-read none of the cited sources; S11, S13, S2, S9, S16, S18, S20 rest on the producer's pinned reading. Published limits are of different kinds. Runway: per-model concurrency by tier (example: Tier 3 allows 5 concurrent Gen-4.5), no requests-per-minute cap, excess tasks queue as THROTTLED, a rolling daily generation cap with 429, and a monthly spend cap. Luma legacy Build tier: Ray 10 concurrent generations and 20 create requests per minute, $5,000 per month. Gemini: RPM/TPM/RPD plus IPM for image models, per project, with spend limits per rolling 10 minutes ($10/$50/$200 by tier); video-model values are only in AI Studio. OpenAI tiers cap monthly usage ($100 to $200,000); model limits are in the console. fal: 2 concurrent requests for new accounts rising to 40. Replicate: 600 prediction requests per minute. Several numeric tables are JavaScript or console only. Curator qualifications: Partially verified: the curator re-read none of the cited sources; S11, S13, S2, S9, S16, S18, S20 rest on the producer's pinned reading. Curator GET 2026-10-23 of the sources not re-read (mechanical source evidence, not semantic verification): S11: HTTP 200, bytes equal to the producer pin; S13: HTTP 200, bytes equal to the producer pin; S2: HTTP 200, bytes equal to the producer pin; S9: HTTP 200, bytes equal to the producer pin; S16: HTTP 200, bytes differ from the producer pin; S18: HTTP 200, bytes equal to the producer pin; S20: HTTP 200, bytes differ from the producer pin. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
