Anthropic releases Claude Haiku 5.5, its cheapest and fastest small model

Anthropic says Haiku 5.5 (claude-haiku-5-5) is live on its API, AWS, Google Cloud and Azure at $0.10 per million input and $0.50 output tokens for prompts up to 100K, about 75% cheaper than Haiku 4.5 on average. It is the first Haiku with an adjustable effort setting and scores 72.4% on OSWorld 2.1 (offline subset). Anthropic also halved Sonnet 5.5 cache reads, from $0.20 to $0.10 per million.
