NVIDIA says Astra autonomously tuned Rubin for another 2x in 72 hours
Relaying NVIDIA's claims, the post says Rubin racks delivered a 3x performance gain over Blackwell out of the box, and OpenAI then pointed Astra at the hardware to gain another 2x fully autonomously over 72 hours.

This sound bite from @sk7037 was crazy - NVIDIA Rubin Racks gave a 3x performance improvement over Blackwell just right out of the box - then because of the building blocks NVIDIA created to optimize its hardware, OpenAI was able to point Astra at it and over 72 hours it gained another 2x in performance on top of the first 3x fully autonomously 🤯
