NVIDIA details how Blackwell GPUs accelerate OpenAI's GPT-6 Astra Ultrafast

GPT-6 Astra Ultrafast runs on NVIDIA Blackwell GPUs and generates tokens up to 8x faster than Astra Standard mode. OpenAI used its own models to tune NVIDIA's GPU inference software, and faster responses cut the wait for coding agents that edit, test and debug in loops.

Why it matters: OpenAI tuned NVIDIA's GPU inference software with its own models, and the speedup targets the wait time coding agents hit when they edit, test and debug repeatedly.
