Limits
Fair-use free tier. No SLA. Limits may change. Best effort.
| Dimension | Value | On exceed |
|---|---|---|
| Requests / minute | 20 / account | 429 + Retry-After |
| Requests / day | 10,000 successful / account (UTC) | 429 |
| Concurrent in-flight | 1 / account | 429 |
| Input cap / request | 8,000 model tokens (state + all questions), max 32,000 UTF-8 bytes | 413 |
| API keys / account | 3 | Create disabled in Console |
Limits are per account and shared by all of its keys (up to 3, for rotation). Daily quota counts successful inference only; rejected, failed or timed-out requests are not charged.
Best practices
- Backoff on
429/504/5xx. - Keep
state+ questions under the soft cap. - One in-flight request per account. Extra keys do not add capacity.
- Do not resell quota or scrape the free tier.
