Routing recommendation
1
Use the fit matrix to compare against cheaper routes when volume rises
Cost pressure
Competitive pricing — $0.21 / M input, $0.57 / M output. Cost pressure is low enough for sustained production use.
Model-fit matrix
Use this model where capability pays for itself; route away where volume, latency, or budget dominate.
| Use case | Fit | Reason | Routing note |
|---|---|---|---|
| Complex reasoning & agentic workflows | Moderate | Intelligence score 18 handles routine reasoning but may struggle with open-ended agentic tasks. | Route simpler sub-tasks here; keep hard reasoning on a stronger model. |
| High-volume chat & customer-facing | Moderate | Output speed may be a bottleneck for real-time chat at scale. | Consider a faster model for latency-sensitive chat. |
| Latency-sensitive applications | Moderate | TTFT 3.00s — latency may be noticeable in interactive use. | Consider routing latency-critical paths to faster models. |
| Cost-sensitive pipelines | Strong | Output pricing at $0.57 is reasonable for moderate volume. | Suitable for production; review costs as volume grows. |
Cost pressure
