OpenAI tests AMD and Cerebras as Nvidia inference chip speed frustrates coding workloads
OpenAI began searching in 2025 for alternatives to Nvidia's inference hardware after internal teams flagged speed constraints in code generation and software-to-software tasks. The company has since signed a deal with Cerebras and is evaluating AMD GPUs to potentially handle about 10% of future inference demand, while talks with Groq ended following a $20 billion Nvidia licensing agreement. A separate plan for Nvidia to invest up to $100 billion in OpenAI remains unresolved, even as both firms publicly emphasize that Nvidia still powers most of OpenAI's inference fleet.

On-Us and Off-Us Card Transactions Shape Fees, Speed and Payment Infrastructure
