An advanced family of AI models with near-human comprehension, powerful vision analysis, and a large context window, designed for tasks ranging from complex reasoning to efficient, responsive text generation.

Try it out

The Claude 3 family of models represents the latest generation of AI from Anthropic, offering a spectrum of options tailored to different performance and cost needs: Opus, Sonnet, and Haiku. These models introduce powerful multimodal capabilities, allowing them to analyze and interpret both text and visual inputs like charts, graphs, and photos. Designed for a broad audience from individual consumers via the claude.ai interface to enterprise developers using the API, they showcase significant improvements in reasoning, accuracy, and reduced refusals. A key differentiator is the standard 200K token context window, enabling deep analysis of long documents and complex conversations. Anthropic continues to emphasize its commitment to AI safety, building on its Constitutional AI framework to create helpful and harmless systems.
