API Available

Claude Haiku 4.5 is Anthropic's latest small AI model, launched on October 15, 2025. It offers similar coding performance to the previous state-of-the-art model, Claude Sonnet 4, but at one-third the cost and more than twice the speed. This model excels in real-time, low-latency tasks, making it particularly beneficial for applications like chat assistants and customer service agents. Claude Haiku 4.5 also enhances the coding experience, providing a responsive environment for multiple-agent projects and rapid prototyping, while maintaining high intelligence and speed.
