Overview


Anthropic is an AI safety company founded by former OpenAI researchers, including Dario and Daniela Amodei. Having raised over $7 billion (including major investments from Google and Amazon), Anthropic focuses on building reliable, interpretable, and steerable AI systems. Their flagship product, Claude, is known for being helpful, harmless, and honest.


Claude models excel at thoughtful, nuanced responses with strong adherence to instructions. Anthropic pioneered "Constitutional AI" to align models with human values without extensive human feedback. Claude has become a top choice for applications requiring careful reasoning, strong safety properties, and large context windows.
