Operator guidance
Route here when quality matters more than latency or cost for hard reasoning tasks. Not a replacement for GPT-4o on standard chat workloads — more expensive and slower.
Use cases
- Complex multi-step reasoning and problem solving
- Advanced coding and debugging
- Scientific and mathematical analysis
Limitations
- High per-token cost; reasoning tokens add to output billing
- Not suitable for latency-sensitive applications
- Capability ratings are qualitative, not a single cited benchmark run
