Encrypted GPT-2 speedrun challenges FHE inference: best is 3.031 s/token, goal sub-1s

tensorqt · x · 2026-10-27

GladiaLab launched the "Encrypted GPT-2 Speedrun", aiming to push fully homomorphic encryption (FHE) inference of GPT-2 from the current best of 3.031 s/tok below the 1.0 s/tok barrier — closing a gap of roughly 4,655× versus plaintext inference.

Rules were released as a thread and the effort is co-signed by crypto VC Paradigm. Teams interested in private inference and FHE optimization can join and compete on the leaderboard.
