Anthropic has raised an additional $4 billion from Amazon, and has agreed to train its flagship generative AI models primarily on Amazon Web Services

It was only back in March that Amazon finished shoveling $4 billion into Anthropic, maker of the Claude family of generative models. Now comes word of another $4 billion, bringing the e-commerce and cloud giant's total investment to – check the math – $8 billion.

Amazon.com pumped another $4 billion into OpenAI competitor Anthropic, as the e-commerce giant goes up against Big Tech rivals in a race to capitalize on generative artificial intelligence technology.
