Claude Haiku 4.5 is Anthropic’s fastest and most efficient AI model, delivering near-frontier intelligence at a fraction of the cost and latency of larger Claude models. It matches Claude Sonnet 4’s performance in reasoning, coding, and computer-use tasks, making it ideal for real-time, high-volume, and latency-sensitive applications. Haiku 4.5 introduces extended thinking, controllable reasoning depth, and robust tool support, including coding, bash, web search, and computer-use tools. It supports a 200,000 token context window, processes both text and images, and is optimized for agentic workflows and multi-agent orchestration. The model is accessible via API and Amazon Bedrock, offering scalable, production-ready deployments.
