Anthropic

Anthropic was founded in 2021 by former OpenAI executives Dario Amodei and Daniela Amodei, along with several other former OpenAI researchers, and is headquartered in San Francisco, California. The company positions itself as focused on AI safety research, studying how to build large-scale AI systems that are steerable and interpretable while pursuing commercial deployment of its models.

Anthropic's primary product is Claude, a family of large language models used for conversational AI, coding assistance, and enterprise applications, accessed through a consumer chat interface, an API, and integrations with cloud providers including Amazon Web Services and Google Cloud. The company has released multiple model generations, including Claude 2, Claude 3, and Claude 3.5, with variants such as Opus, Sonnet, and Haiku targeting different performance and cost tradeoffs. Enterprise and developer customers use Claude for tasks including software development, customer support automation, and document analysis, and the models are also integrated into third-party products from companies such as Slack and Notion.

The company has raised capital from investors including Google, Amazon, Spark Capital, and Menlo Ventures across multiple funding rounds, with Amazon committing up to $4 billion and Google committing roughly $2 billion in separate investments. Anthropic has grown to employ well over a thousand people and has published AI safety research including work on Constitutional AI and model interpretability.
