Claude is a family of state-of-the-art large-language models developed by Anthropic. First released to the public on 14 March 2023, the Claude series is engineered to be helpful, honest and harmless, offering advanced capabilities in reasoning, coding, writing, multilingual dialogue and image understanding.
Built by a team of former OpenAI researchers — including co-founders Dario Amodei, Daniela Amodei, Jared Kaplan, Jack Clark and Ben Mann — Claude has evolved rapidly through multiple generations (Claude 2, Claude 3, and the latest Claude 4 models). These iterations expand context windows to hundreds of thousands of tokens and introduce novel features such as Artifacts (live code/doc previews) and multimodal inputs, positioning Claude as a leading competitor to ChatGPT and Gemini.
Accessible via the web, mobile apps, a desktop client and an API, Claude helps individuals and enterprises accelerate research, ideation and content creation while adhering to Anthropic’s Constitutional AI framework for safety-aligned outputs.
