Anthropic announced Claude Haiku 5.5 on October 7, 2026, with lower token pricing for prompts up to 100,000 tokens and a higher tier above that cutoff.
According to the Anthropic launch page, prompts up to 100,000 tokens cost $0.10 per million input tokens and $0.50 per million output tokens. For prompts above 100,000 tokens, pricing shifts to $0.50 for input and $2.50 for output per million tokens.
Anthropic says about 90% of requests to the previous Haiku model fell into the lower band, which suggests many short-prompt classification, extraction, and routing workloads could see the cheaper rate. Haiku 5.5 is available now on Anthropic’s platform, AWS, Google Cloud, and Microsoft Azure.
There is a pricing caveat: Anthropic says Haiku 5.5 uses an updated tokenizer that can use slightly more tokens per task. And while the launch page compares Haiku 5.5 against Haiku 4.5 at $1 and $5 per million input/output tokens, Anthropic’s current pricing docs list Haiku 4.5 at $0.50 and $2.50, so the exact discount depends on which baseline you use.
