PANews, June 18 – Amazon (AMZN.O) is in talks to sell its self-developed AI chips to other companies' data centers, a move that marks a further expansion of its efforts to challenge Nvidia's dominance. Peter DeSantis, head of Amazon's AI business, said: "We believe AI infrastructure is evolving rapidly. We are always looking for ways to serve more customers." Amazon launched its AI accelerator chip, Trainium, in 2020. The chip has already attracted some heavyweight customers, including OpenAI, Anthropic, and Uber, which use the related hardware through Amazon Web Services (AWS). Amazon stated in April this year that Trainium has secured over $225 billion in revenue commitments. That same month, CEO Andy Jassy said it is "entirely possible" that Amazon will sell whole rack chip equipment to third parties. This is also part of the company's strategy to reposition itself around artificial intelligence. DeSantis said the third-generation Trainium chip, which began shipping earlier this year, is "basically sold out." Amazon stated that the fourth-generation Trainium chip, expected to launch next year, has already attracted strong demand.
