$NVDA CONFIRMS GPT-6 ASTRA ULTRAFAST RUNS ON BLACKWELL Astra Ultrafast can deliver up to 8x faster token generation than Astra Standard. OpenAI used its own internal models to optimize inference on NVIDIA GPUs, including high-performance kernels built around Blackwell’s architecture. OpenAI inference lead Philippe Tillet: Astra can generate kernels that improve “latency, throughput and cost” on NVIDIA hardware.
