About Anthropic

Anthropic is an AI safety company that builds Claude, one of the most capable large language models available. Founded in 2021 by Dario Amodei, Daniela Amodei, and other former OpenAI researchers, Anthropic was established with a mission to develop AI systems that are safe, beneficial, and understandable.

The company's founding thesis is that AI safety research is best conducted by an organization that is also building frontier AI systems. This approach — developing cutting-edge capabilities alongside safety techniques — distinguishes Anthropic from both pure commercial AI companies and academic safety research labs. Constitutional AI, the company's core alignment technique, trains models to evaluate their own outputs against a set of principles, reducing harmful content without extensive human annotation.

Claude has emerged as a leading competitor to GPT-4, particularly valued for its strong reasoning, long context windows (up to 200K tokens), careful and nuanced responses, and reduced tendency toward hallucination. Anthropic's API serves enterprise customers across healthcare, legal, finance, and technology, while Claude.ai provides direct consumer access. The company has raised over $7.3 billion, with major investments from Google and Amazon.

Technology & Approach

Anthropic's research focuses on Constitutional AI (CAI), interpretability, and scalable oversight. Constitutional AI replaces traditional RLHF with a principle-based self-evaluation process where the model critiques and revises its own outputs. The company's interpretability research aims to understand what neural networks have learned at a mechanistic level — identifying specific circuits responsible for specific behaviors. Anthropic also conducts research on AI evaluations, red-teaming, and responsible scaling policies that define safety thresholds for deploying increasingly capable models.
