History

Anthropic was founded in 2021 by Dario Amodei, Daniela Amodei, and several other former OpenAI researchers. The company is headquartered in San Francisco and operates as a public-benefit corporation.

Its main product is Claude, a family of large language models offered through a consumer chat interface, an API, and integrations with cloud platforms. Research lines published by the company include Constitutional AI, mechanistic interpretability work on transformer internals, and a “Responsible Scaling Policy” that ties capability releases to specified safety thresholds.

Anthropic has raised funding from Google and Amazon, with Amazon committing up to $4 billion in 2023 and additional investment in subsequent rounds. The company also distributes Claude through Amazon Bedrock and Google Cloud Vertex AI alongside its own surfaces.
