According to a source familiar with the transaction, Alphabet Inc.'s Google has invested about $400 million in artificial intelligence firm Anthropic, which is testing a competitor to OpenAI's ChatGPT. Anthropic and Google declined to comment on the investment, but they did announce a collaboration in which Anthropic will employ Google's cloud computing services. The agreement is the latest collaboration between a tech behemoth and an AI startup, as the field of generative AI — technology that can generate literature and art in seconds — heats up. According to the individual who asked not to be identified because the terms were confidential, the purchase provides Google a share in Anthropic but does not oblige the business to spend the funds on Google cloud services.
