Anthropic: the company behind Claude

Anthropic develops Claude and researches how to make advanced AI systems more understandable and controllable. This company guide explains the distinction between the organisation, its AI models and the applications built around them—and how to assess its safety commitments without confusing intentions with demonstrated results.

What is Anthropic?

Anthropic describes itself as an AI safety and research company. Its company statement identifies it as a public benefit corporation and explains that stockholders and its Long-Term Benefit Trust elect its board. The corporate structure and stated mission describe how the business is organised; they do not, by themselves, establish that a particular model is safe or reliable in every setting.

Anthropic’s May 2021 funding announcement named Dario Amodei as chief executive and Daniela Amodei as president. It set out a research agenda centred on reliability, interpretability and human feedback. That announcement is a historical record, not a statement of the company’s current valuation or financing position. For the person behind the company’s public arguments, see Nuvastra’s Dario Amodei profile.

Anthropic and Claude are not the same thing

Anthropic is the organisation. Claude is the name used for its AI models and assistant. A model is the underlying system that produces outputs; an application supplies the interface, tools and surrounding controls. An API lets developers connect model capabilities to their own software. These distinctions matter when comparing features, permissions or costs: a capability available in one application is not automatically available through every route to the model.

Anthropic introduced Claude on 14 March 2023, describing access through a chat interface and an API, with uses including summarisation, writing, questions and answers, and coding. That launch date belongs to the original Claude announcement. It should not be used as the release date of every subsequent Claude model or product.

What does Anthropic mean by AI safety?

The company’s research interests include interpretability—investigating how a model arrives at its behaviour—and methods for guiding model responses. Its Claude constitution sets out intended values and behaviour and describes a role in training. Anthropic explicitly acknowledges that model behaviour may depart from those intentions.

That qualification is central to reading the document accurately. A constitution is evidence of an intended training direction, not proof that every response will follow it. Evaluating a deployed system requires evidence about the exact model, the task, the tools it can use and the safeguards around those tools. A claim about safer behaviour should therefore identify the test and its limits, rather than rely on a company’s mission statement.

How to assess a Claude deployment

Start by recording the exact model identifier, application or API provider, and the date of the assessment. Then specify what successful work looks like: for example, an answer supported by the supplied documents, or a code change that passes an agreed test suite. This is a practical assessment framework, not a Nuvastra benchmark result.

Keep capability and authority separate. Producing a plausible answer does not establish that a system should be allowed to send messages, change records or act without review. Record which actions require approval, what happens when evidence is missing, and whether failures can be detected and reversed. Compare completed, checked outcomes rather than impressive individual demonstrations.

Scope and updates

This profile deliberately does not present a live model catalogue, price list, ownership-percentage table or valuation. Those details require separate, dated records and can change without altering the distinction between Anthropic and Claude. The linked company documents are primary sources for Anthropic’s own statements; they are not independent certification of its performance.
