Gemini Omni rate limit: Google lists none, Sume lists them

Google's Gemini API rate-limits page, read 2026-10-08, has no row for Gemini Omni or Veo. It describes limits in requests per minute (RPM), tokens per minute (TPM) and requests per day (RPD), applied per project, and it caps spend per 10 minutes by tier: $10 on Tier 1, $50 on Tier 2 and $200 on Tier 3. For model-specific video limits it points you to AI Studio. If you need a number you can plan around, Sume publishes one for its own API.

So the honest answer to the query is that Google does not publish an Omni limit on that page.

What each side publishes

The Google row set is about projects. Sume's is about API keys and plans. They measure different things, so compare the structure, not the numbers.

Sume's limits in practice

Sume reads are allowed at 40 times the write rate, so polling a job does not use up your submit budget. A 429 names error.details.scope as read or write, and responses carry ratelimit-limit, ratelimit-remaining, ratelimit-reset and retry-after headers. A separate admission control limits queued and accepted jobs: Pro allows 4 running, 20 queued and 24 accepted, and a request beyond that returns 429 queue_full. A job you cannot afford returns 402 insufficient_credits.

What to do with an unknown limit

If you call Google directly, open AI Studio for the live limit for your project and treat the number as something that can change. Build a retry that honors the server's delay. If you call Sume, read retry-after and use the scope in the error to decide whether to slow submits or polling. Either way, submit in waves sized to the concurrency, not to the request rate.

Reading a 429 from Sume

A rate-limit 429 from Sume carries error.details.scope, which is read or write. A queue_full 429 is a different case: you are within the request rate but over the accepted-job count for your plan (24 on Pro, 48 on Startup, 120 on Scale, 6 on Free). Wait for jobs to finish; slowing the request rate will not help.

A 402 insufficient_credits means the balance cannot cover the reserve at submit. Add credit and resubmit with the same Idempotency-Key so you are not billed twice for one clip.
