What Is Claude AI?

Claude is an advanced family of large language models (LLMs) developed by Anthropic, an AI research company founded in 2021 by former senior OpenAI executives including Dario Amodei and Daniela Amodei.

Anthropic built Claude using a proprietary alignment methodology called Constitutional AI. Instead of relying solely on human feedback rating systems (RLHF), Constitutional AI trains the model against an explicit set of ethical principles and guidelines. This approach produces an AI assistant designed to be polite, reliable, steerable, and resistant to prompt injection attacks. Official technical whitepapers and safety research can be explored directly on Anthropic's official research portal.
