Anthropic's family of large language models, known for long context, strong reasoning, and a safety approach called Constitutional AI.
Claude is the assistant developed by Anthropic. Its alignment relies in part on Constitutional AI (Bai et al., 2022), in which the model is trained to critique and revise its own outputs against a written set of principles rather than depending solely on human labels for harmful content.
