About

About Anthropic

Founded in 2021 by former OpenAI researchers Dario and Daniela Amodei, Anthropic pioneered Constitutional AI — a training approach that improves safety by having AI systems critique and revise their own outputs. The Claude model family is known for long context windows, extended chain-of-thought reasoning, and strong performance on research, coding, and agentic workflows.
