NVIDIA's October 1 post says its GPUs accelerate OpenAI's GPT-6 Astra Ultrafast, a faster-response mode of the Astra model offered through the OpenAI API and to eligible ChatGPT Work and Codex users. NVIDIA claims up to 8x faster token generation than Astra Standard mode, with no absolute speeds or pricing given. The post names Blackwell GPUs without a specific configuration, so it signals inference demand rather than a disclosed contract.

• OpenAI GPT-6 Astra Ultrafast runs on NVIDIA Blackwell GPUs (per NVIDIA)
