As Anthropic’s sales explode, straining the servers it uses, the company is considering adding another source of AI server chips in addition to existing suppliers Google, Amazon and Nvidia.

The maker of Claude has recently been in talks with London-based startup Fractile to buy its inference chips, which aim to run AI models efficiently, when the chips become available next year, according to two people who have spoken to Fractile leaders. Deals such as these would give Anthropic more leverage with suppliers just at the time when its spending on servers and chips is projected to reach tens of billions of dollars a year.
