US E-commerce giant Amazon is investing an additional $4 billion in artificial intelligence (AI) firm Anthropic, marking a strategic collaboration.

According to Turkish news service Anadolu, Anthropic will use Amazon’s cloud solution, Amazon Web Services (AWS), as its primary provider and will leverage AWS’s Trainium and Inferentia chips to train its AI models.

“We’ll keep pushing the boundaries of what customers can achieve with generative AI technologies,” said AWS CEO Matt Garman in a statement.

Known for its Claude family of large language models (LLMs) and AI tools, Anthropic comptets with OpenAI’s ChatGPT.

The latest investment follows Amazon’s earlier announcements to invest $1.25 billion in Anthropic in September 2023 and $2.75 billion in March 2024. So, far Amazon’s total investment in Anthropic has thus reached $8 billion.
