01 / QUICK DECISION
Choose for the workload, not only the token rate.
A cheaper model may use a different number of tokens or need more retries. Test on your own workload.
Choose Haiku
For high-volume summarization, classification, routing, compaction and real-time experiences where speed and unit cost matter.
Choose Sonnet
For well-scoped coding, agents and everyday production work that needs a stronger balance of capability, latency and price.
Choose Opus
For complex, long-running work where judgment and reliability matter more than the lowest token cost.
