How NVIDIA GPUs Help Accelerate OpenAI's GPT-6 Astra Ultrafast
NVIDIA, Thursday, October 1st, 2026
GPT-6 Astra Ultrafast runs on NVIDIA Blackwell GPUs and delivers up to 8x faster token generation than Astra Standard.
OpenAI's GPT-6 Astra Ultrafast, now in the OpenAI API and for eligible ChatGPT Work and Codex users, runs on NVIDIA Blackwell GPUs.
Inference optimizations that exploit the Blackwell architecture give up to 8x faster token generation than Astra's standard mode.
NVIDIA says the speedup matters most in repeated agent loops, shortening coding agents' edit-test-debug cycles and reducing time between tool calls in interactive applications.
