Report: OpenAI to power GPT-6.1 Sol "Ultrafast" mode with Nvidia GPUs instead of Cerebras hardware
Research firm SemiAnalysis posted on X on Wednesday (2026-09-30) that OpenAI will power its "Ultrafast" mode for the GPT-6.1 Sol AI model with Nvidia graphics processing units instead of Cerebras hardware.
