Below is a list of all available snapshots and aliases for Daybreak Red. daybreak-red-latest gpt-5.6-cyber gpt-5.6-cyber Rate limits Rate limits ensure fair and reliable access to the API by placing specific caps on requests, tokens, audio duration, or other usage within a given time period. Your usage tier determines how high these limits are set and automatically increases as you send more requests and spend more on the API. | Tier | RPM | TPM | Batch queue limit | |---|---|---|---| | Free | Not supported | || | Tier 1 | 500 | 500,000 | 1,500,000 | | Tier 2 | 5,000 | 1,000,000 | 3,000,000 | | Tier 3 | 5,000 | 2,000,000 | 100,000,000 | | Tier 4 | 10,000 | 4,000,000 | 200,000,000 | | Tier 5 | 15,000 | 40,000,000 | 15,000,000,000 |
