Anthropic launches cheaper AI model Claude Haiku 4.5

Anthropic has introduced Claude Haiku 4.5, a new AI model designed to be faster and more cost-effective than its predecessors. This release aims to make advanced AI capabilities more accessible to a broader range of users.

Anthropic introduced Claude Haiku 4.5, its fastest and most efficient small AI model to date. This model delivers coding performance comparable to Claude Sonnet 4 but at one-third the cost and more than twice the speed.

It achieved a 73% score on the SWE-Bench Verified benchmark and a 41% score on Terminal-Bench, rivaling OpenAI's GPT-5 and Google's Gemini 2.5 in coding and command-line tasks.

Haiku 4.5 is available to all users on Anthropic's free plan and can be accessed via Claude's API, Amazon Bedrock, and Google Cloud Vertex AI.
