Nvidia Confirms GPT-6 Astra Ultrafast Runs on Blackwell

$NVDA confirms GPT-6 Astra Ultrafast is running on Blackwell GPUs, delivering up to 8x faster token generation than Astra Standard.
OpenAI used its own internal models to optimize inference directly for NVIDIA hardware, including high-performance kernels designed around Blackwell's architecture.
OpenAI inference lead Philippe Tillet says Astra can generate kernels that improve latency, throughput and cost on NVIDIA hardware.
