Anthropic is launching Claude Haiku 4.5, the newest version of the generative AI (genAI) company’s smallest language model. The company says it offers the same performance as Sonnet 4, but at a third of the cost and more than twice the speed. Haiku 4.5 reportedly performs on par with Sonnet 4, OpenAI’s GPT-5, and Gemini 2.5
