Frontier reasoning model for code and research
The model I would reach for when correctness matters more than pace.
Use it as the escalation model, not the cheap default.
- Context fit
- Long technical briefs
- Latency class
- Deliberate
- Cost shape
- Premium per solved hard task
- Reliability
- Excellent
- Speed
- Moderate
- Cost discipline
- Needs routing
It is strongest when a task has moving parts: code review, multi-file edits, architecture tradeoffs, or agent plans that need to survive several turns. The catch is tempo. For short customer replies or bulk extraction, the extra deliberation feels expensive instead of helpful.
- Watch
- Latency is the tax. It should be routed selectively, not made the default for every prompt.
- Best for
- Senior-code workflows, planning agents, technical research, and review gates.
