Anthropic, which operates a chatbot called Claude, has sought to position itself as one of the industry’s more responsible actors. Its executives have warned that A.I. could cause tremendous damage to society if not developed carefully. The company’s co-founder, Jack Clark, attended a recent meeting on Capitol Hill to discuss A.I. policy, including the risks and potential of the rapidly evolving technology.

Partnering with Anthropic is a win for Amazon, which is competing against Microsoft and Google in cloud computing and has been trying to establish itself more deeply in A.I. Amazon is also battling Nvidia as a provider of the chips needed to run complex A.I. systems.

The huge amounts of money and computing power needed to run A.I. models have made it nearly impossible for smaller companies to remain independent from established tech giants with deep pockets. Yet while Microsoft has backed OpenAI and Google has partnered with companies including Cohere, Amazon has not been as active in the field until its deal with Anthropic.

“We can help improve many customer experiences, short- and long-term, through our deeper collaboration,” Andy Jassy, Amazon’s chief executive, said in a statement.
