Claude 3.5 Sonnet / Claude 4.1 Opus

Claude is a family of large language models developed by Anthropic, an American AI safety and research company. First released in early 2023, Claude was designed to be helpful, honest, and harmless, utilizing a technique known as 'Constitutional AI' to guide its behavior and ethical decision-making.

The development of Claude takes place primarily in the United States, utilizing high-performance computing clusters. As a cloud-native software product, it does not have a physical manufacturing location but is deployed via global data center infrastructures. The brand is positioned as a leading competitor in the generative AI space, known for its high reasoning capabilities and large context windows.

Anthropic was founded by former executives of OpenAI, Dario and Daniela Amodei. While it remains an independent company, it has received multi-billion dollar investments from major technology firms like Amazon and Google. However, as of late 2025 and 2026, Anthropic continues to operate as an independent Public Benefit Corporation based in San Francisco.
