"Despite its smaller size, Haiku 4.5 demonstrated similar levels of coding performance on the SWE-bench verified to Claude Sonnet 4, which, when launched four months ago, Anthropic claimed was the world's best coding model. The company said Haiku 4.5 can even surpass Claude Sonnet 4 in tasks such as computer usage while being one-third the cost and twice the speed."
"All users will be able to put Haiku 4.5 to the test, as the model is available in Claude apps, including the Claude.ai chatbot. Beyond coding capabilities, the model performed competitively against Claude Sonnet 4.5, the company's flagship LLM that launched at the end of September, on a series of benchmarks, including the MMMU, which tests for visual reasoning; AIME 2025, which tests for high school-level math; and r2-bench, which evaluates for an agentic tool user."
Anthropic released Haiku 4.5, a small language model optimized for speed and cost-efficiency and available on Claude.ai free plans. Haiku 4.5 matches SWE-bench coding performance of Claude Sonnet 4 and can outperform Sonnet 4 on computer-usage tasks while costing one-third and running twice as fast. The model's high speed and advanced capabilities suit real-time, low-latency chatbot tasks and it is accessible within Claude apps. Haiku 4.5 also performed competitively with Claude Sonnet 4.5 across benchmarks including MMMU, AIME 2025, and r2-bench. Safety evaluations show low rates of concerning behaviors and higher alignment than several prior models, making it the company's safest model yet.
