Operator guidance
Route here for the most demanding reasoning/coding/agentic work when quality matters more than latency or price. Drop to Sonnet 4 for the usual price/performance balance, or Haiku 4 for high-volume, latency-sensitive work.
Use cases
- Hardest reasoning, agentic, and coding tasks where quality dominates cost
- Long-context analysis and multi-step tool/agent workflows
Limitations
- Highest price and latency of the Claude 4 tiers
- Capability ratings are qualitative (vendor + community signal), not a single cited benchmark run
