Doubleword: Open-Weights LLMs Will Close the Frontier Gap to Zero by December 3, 2026
Doubleword / Hacker News·medium signal
A Doubleword analysis (251 points on HN) measures the open-vs-closed gap as the time lag for open weights to reach the closed frontier's past benchmark levels; the gap has shrunk reliably since summer 2024, and a line of best fit hits zero months around December 3, 2026. Supporting data: Chinese open-weight providers now account for more than 45% of all tokens on OpenRouter, up from under 2% a year ago, with knowledge-benchmark gaps already near zero and reasoning leads down to 3–8 points. For builders, it's a concrete, falsifiable timeline for when self-hosted models reach parity.
