Amazon pours an additional $2.75 billion into AI startup Anthropic

Amazon says it is pouring an additional $2.75 billion into Anthropic, bringing its total investment in the artificial intelligence startup to $4 billion. Amazon will maintain a minority stake in San Francisco-based Anthropic, a rival of ChatGPT maker OpenAI. The two companies are collaborating to develop so-called foundation models, which underpin the generative AI systems that have captured global attention. Amazon made an initial investment of $1.25 billion in Anthropic in September and indicated then it had plans to invest up to $4 billion.
