Anthropic Launches Claude Haiku 5.5 and Reduces Sonnet 5.5 Caching Costs
Anthropic has launched Claude Haiku 5.5, its cheapest and fastest small model, at up to 90% lower per-token prices than Haiku 4.5, and halved the cache read price on Sonnet 5.5. We explain the two price tiers, the tokenizer catch, the benchmarks and early customer results, the arithmetic behind the 20% Sonnet saving, the new monthly API credits for Max and Team plans, and the breaking changes developers must handle before switching.
