Anthropic Launches Claude Haiku 4.5: Near-Frontier Performance at $1/$5 per Million Tokens

Anthropic has released Claude Haiku 4.5, a small model priced at $1/$5 per million input/output tokens that delivers coding performance comparable to Claude Sonnet 4 at one-third the cost and more than twice the speed. The model surpasses Sonnet 4 on computer use tasks and achieves 90% of Sonnet 4.5's performance on agentic coding evaluations, running 4-5x faster than Sonnet 4.5. Notably, Haiku 4.5 is classified under ASL-2 safety standards—less restrictive than the ASL-3 applied to Sonnet 4.5 and Opus 4.1—and is described as Anthropic's safest model by automated alignment metrics. It is available via the Claude API, Amazon Bedrock, and Google Cloud Vertex AI.
