RT Trevor Cai (@trevorycai)3 years ago, we emailed Jensen with requests for Blackwell. Today, we released GPT-5.3-Codex, a SOTA model designed for GB200-NVL72. Nitpicking ISA, simming rack designs, and tailoring our arch to the system has been a fun experience! I'm grateful to our collaborators at NVIDIA. https://t.co/ZIv57Bdh9A ...
