Claude
Also known as: Anthropic Claude
Definition
Claude is the family of large language models built by Anthropic, available through the Claude.ai web app, mobile apps, the Claude desktop app (home of Claude Cowork), Claude Code, and the Anthropic API.
Claude is known for strong reasoning, long context, careful instruction-following, and a focus on safety. The same underlying intelligence powers several products: Claude.ai for chat, Claude Code for development, and Claude Cowork for agentic desktop work.
When people compare 'Claude vs ChatGPT,' they're comparing Anthropic's Claude with OpenAI's GPT-powered products. Which fits best depends on the task, the team, and the workflow.
