Benchmarks and specs

Best fit
Claude Haiku 4.5 is best for fast assistants, high-volume API calls, classification, extraction, lightweight agent steps, and multimodal tasks where official Anthropic pricing is required.
Use a larger Claude tier when the task needs the strongest reasoning or long-horizon coding performance rather than the Haiku speed-and-cost tradeoff.
