Anthropic
AI safety company building reliable, interpretable, and steerable AI systems including the Claude model family
Overview
Anthropic is an AI safety company founded in 2021 by former OpenAI research executives Dario Amodei and Daniela Amodei. The company develops the Claude family of large language models, known for their strong reasoning capabilities, large context windows, and safety-first design. Anthropic pioneered Constitutional AI (CAI), a training approach that uses a set of principles to guide model behavior. Claude models power both consumer products (claude.ai) and developer APIs, competing directly with OpenAI's GPT series and Google's Gemini. With backing from Google, Salesforce, and Amazon, Anthropic has raised over $8 billion and is valued among the most valuable AI startups globally.
