About Claude

Claude is an AI assistant developed by Anthropic, a safety-focused AI research company founded in 2021 by former OpenAI researchers including Dario and Daniela Amodei. Claude is designed to be helpful, harmless, and honest, built using Anthropic's Constitutional AI approach that trains the model to follow a set of principles rather than relying solely on human feedback. The Claude model family has evolved rapidly, with Claude 3.5 Sonnet and Claude 3 Opus establishing the platform as a leading alternative to ChatGPT. Claude is available through the claude.ai web interface, mobile apps, and Anthropic's API. Key differentiators include a large context window supporting up to 200K tokens (enabling analysis of entire codebases or long documents), strong performance on coding and reasoning tasks, and a commitment to safety research. Claude is used by enterprises including Amazon (through AWS Bedrock), Notion, DuckDuckGo, and thousands of developers building AI applications. Anthropic has raised over $7 billion in funding, with significant investment from Amazon and Google.
