Live routing data
Performance and reliability
Recent averages across requests routed for this model. Your own speed depends on prompt length, reasoning effort and load.
- Throughput
- 78.3 tok/s
- Faster than 52% of 253 models
- Time to first token
- 3.4 s
- Quicker than 51% of 253 models
- Prompt cache hits
- 65.5%
- About $0.27 per 1M input tokens with caching
- Request success (24h)
- 99.9%
- Reliable
Cache hits are the share of input tokens recently served from a prompt cache across all requests. They are not a forecast of your own hit rate.
- Healthy (98% or more)
- Degraded (90–98%)
- Down (under 90%)
- No requests
