Overview
About Anthropic
Anthropic is an AI safety company founded in 2021 by Dario and Daniela Amodei along with several other former senior OpenAI researchers. The company's founding thesis is that AI safety and AI capability research are best pursued together — that building the most capable systems provides the best testbed for safety research. Anthropic's flagship product is Claude, a family of AI assistants known for their nuanced reasoning, careful handling of sensitive topics, and strong instruction-following capabilities. Claude has rapidly gained adoption in enterprise settings, particularly among organisations that prioritise safety, reliability, and thoughtful AI behaviour. The company's research contributions include Constitutional AI (a method for training AI using a set of principles rather than human feedback alone), mechanistic interpretability work, and scaling laws research. Anthropic's investor base includes Amazon (which has committed up to $4 billion), Google, and Salesforce Ventures.

FAQ
Frequently asked questions
The founders left OpenAI in 2021 due to disagreements about the company's direction, particularly around safety practices, governance, and the pace of scaling AI systems. They founded Anthropic to pursue AI development with safety as a core priority.
Constitutional AI is Anthropic's training methodology where the model is guided by a set of written principles (a 'constitution') rather than relying solely on human feedback. This approach aims to produce AI that is helpful, harmless, and honest in a more scalable way.
Claude tends to excel at nuanced reasoning, longer context processing (200K vs 128K), and careful handling of sensitive topics. ChatGPT has a larger ecosystem, more features (image/video generation), and broader consumer adoption. Both are frontier-class AI assistants.
Amazon has committed up to $4 billion in Anthropic, making it the largest investor. Claude is available on Amazon Bedrock, and Anthropic uses AWS as its primary cloud infrastructure provider. This partnership provides enterprise distribution and compute resources.
Anthropic is a venture-funded company focused on growth. Like most frontier AI companies, it is investing heavily in research and infrastructure. Revenue has grown significantly with Claude adoption, but the company has not disclosed profitability.
