Claude

Claude is a family of large language models developed by Anthropic.[1][2] The first model was released in March 2023. The Claude 3 family, released in March 2024, consists of three models: Claude Haiku optimized for speed, Claude Sonnet balancing capabilities and performance, and Claude Opus designed for complex reasoning tasks. These models can process both text and images, with Claude 3 Opus demonstrating enhanced capabilities in areas like mathematics, programming, and logical reasoning compared to previous versions... Claude 3.7 Sonnet was released on February 24, 2025. It is a pioneering hybrid AI reasoning model that allows users to choose between rapid responses and more thoughtful, step-by-step reasoning. This model integrates both capabilities into a single framework, eliminating the need for multiple models. Users can control how long the model "thinks" about a question, balancing speed and accuracy based on their needs. Anthropic also launched a research preview of Claude Code, an agentic command line tool that enables developers to delegate coding tasks directly from their terminal. https://en.wikipedia.org/wiki/Claude_(language_model)
