Extropic teases Z1T-0.1 as it races from GPT-2 toward GPT-3-level models
beffjezos · x · 2026-09-05
Extropic announced Z1T-0.1 is coming soon and revealed how fast its Z1 architecture is scaling: current models are "barely GPT-2 level," and the team started a new training run overnight to see if it could hit GPT-3 level by the weekend. Per its scaling law, training the same performance on GPUs costs 10-15x more flops due to wasteful matmuls that don't exist on Z1 hardware, while parameter counts stay the same.
