What Is Claude?

Claude is an artificial intelligence chatbot created by Anthropic, a company founded in 2021 by former OpenAI researchers, including siblings Dario and Daniela Amodei. The company’s mission is to develop AI systems that are safe, aligned with human values, and easy to reason with. This philosophy led to the creation of the Claude series, which focuses on accuracy, ethical behavior, and user trust.

The name “Claude” pays homage to Claude Shannon, the mathematician who pioneered information theory. Like its namesake, the system is built around understanding and structuring information clearly and logically.

Claude operates on a family of large language models trained to process, summarize, and reason across massive amounts of text. The latest release, Claude 3.5, supports multimodal inputs, allowing users to upload documents, spreadsheets, and images for analysis.
