Why teams choose it

💡

Cost-aware reasoning depth

Helps teams that prioritize token economics but still want multi-step reasoning and strong coding assistance validated on their workloads.

⚙️

Coding and tools

Works well for code assistance, tool calling, and agent workflows where instructions must stay consistent across steps.

🔬

Bench before you reroute traffic

Useful once you rerun your own evaluation harness—routing decisions should survive your retrieval shape, tooling, and safety filters.

✍️

Cost-efficient routing

Useful as part of a routing stack where cheap models handle drafts and confirmations and this tier handles genuinely hard passages.
