2026 04 08 Anthropic
Anthropic is an AI safety company founded in 2021 that develops large language models and AI systems with emphasis on safety and interpretability. The company was established by former members of OpenAI, including Dario and Daniela Amodei, and focuses on creating AI systems designed to be more reliable and aligned with human values.
Constitutional AI
Anthropic’s primary research contribution is constitutional AI, a training methodology that uses a set of principles or “constitution” to guide model behavior during development. Rather than relying solely on human feedback, this approach allows models to evaluate and improve their own outputs against stated principles, aiming to produce systems that are more transparent in their reasoning and resistant to misuse.
Claude
The company’s main product is Claude, a large language model available through various interfaces including API access and a web application. Claude is designed with safety considerations embedded throughout its development process, distinguishing it from some competing language models through explicit focus on reducing harmful outputs while maintaining capability for complex reasoning tasks.
