Claude Haiku 4.5 is Anthropic’s fastest and most efficient model, offering near-frontier intelligence with much lower cost and latency than larger Claude models. It matches Claude Sonnet 4’s performance in reasoning, coding, and computer-use tasks, making it ideal for real-time and large-scale applications. Haiku 4.5 introduces controllable reasoning depth, supports summarized or interleaved thought outputs, and enables tool-assisted workflows across coding, bash, web search, and computer-use tools. With over 73% on SWE-bench Verified, it stands among the top coding models while maintaining fast responsiveness for sub-agents, parallel execution, and scaled deployment.
