OpenAI's first AI accelerator fails to beat Nvidia's Blackwell in terms of raw performance, but it can offer very good performance-per-watt and low latency, which is exactly what the doctor ordered for inference workloads.

128 chips, 1.7 exaFLOPS, and 27 TB of HBM give Altman and crew a leg up over Blackwell, and maybe even Rubin

OpenAI still isn’t giving up Nvidia chips, though.
