Claude Haiku 4.5

Claude Haiku 4.5, the latest model from Anthropic, is designed to provide fast and efficient performance, particularly excelling in coding tasks. It matches the coding capabilities of its predecessor, Claude Sonnet 4, but operates at twice the speed and at one-third of the cost. This model is especially suited for applications requiring real-time, low-latency operations, such as chat assistants and customer service agents, as well as coding tasks like pair programming and rapid prototyping. Claude Haiku 4.5 is noted for its ability to handle complex workflows with intelligence and speed, making it an ideal choice for developers using AI in feedback loops.

The model's efficiency allows for more work to be accomplished within usage limits while maintaining high performance. It is available via Claude's API, Amazon Bedrock, and Google Cloud’s Vertex AI, serving as a cost-effective replacement for earlier models. In terms of safety, Claude Haiku 4.5 has undergone extensive evaluations, showing lower rates of concerning behaviors and achieving a higher alignment than its predecessors, leading to its classification under the AI Safety Level 2 standard. This makes it the safest model from Anthropic to date, with limited risks in producing hazardous materials.

Claude Haiku 4.5 stands out not only for its speed and cost-efficiency but also for its advanced safety features, making it a robust option for developers seeking high-performance AI solutions.
