What is Claude?

Claude is Anthropic's family of frontier AI models, designed for reliability, careful reasoning, and safe agentic behavior. The lineup spans tiers: Claude Sonnet for the best balance of speed and intelligence, Claude Opus for the deepest reasoning on complex tasks, and Haiku-class variants for fast, lightweight responses.

Anthropic trains Claude with Constitutional AI techniques, which makes the model unusually careful about following instructions, citing its work, and avoiding hallucinations during long-running agent loops. Claude excels at long-form coding, multi-step refactors, technical writing, and tool use across thousands of turns.

Models like Claude Sonnet 4.6 and Claude Opus 4.7 ship with 1M-token context windows and improved agentic coding, making them a strong default for builders who need a model that stays on task.
