Anthropic
The AI safety company that builds Claude — founded in 2021 by former OpenAI researchers, including Dario and Daniela Amodei. Anthropic's core thesis is that the most important thing a company can do right now is build AI safely and work to understand it deeply. They publish their safety research publicly, maintain a strict safety framework (ASL levels), and operate as a public benefit corporation. They are one of the leading AI labs globally alongside OpenAI and Google DeepMind.
In practice
When you use Claude — whether through Claude.ai, the API, or a third-party app built on Claude — Anthropic is the company behind the model. They set the safety policies, train the model, run the infrastructure, and decide what Claude will and won't do. Every Claude behavior traces back to decisions Anthropic made during training.
