Base text-token rates. Long-context pricing, tool charges, service tiers, and provider selection can change the total. Cache creation is charged when writing tokens to the cache; cache read applies when reusing them. The default cache duration applies unless labeled otherwise. Unsupported cache rates are marked unavailable.

Estimated query cost combines your input-token count with the model’s average output, rounded to whole tokens, at current standard rates. It assumes uncached input and excludes tool charges. This is an estimate for that workload, not a measured average total bill.

Claude Haiku 4.5

claude-haiku-4-5-20251001

Claude Haiku 4.5 matches Sonnet 4's coding quality while running about twice as fast at roughly one-third the price, making it ideal for low-latency chat assistants, support bots, and pair programming. Pair it with Sonnet 4.5 to plan complex work and fan out execution across parallel Haiku workers.
