Woofun AI notes that the performance divergence between open-source AI architectures and proprietary frontier models has accelerated significantly. Citing Epoch AI's Capability Index, analyst Miles Deutscher highlights that the historical 12-month lag has compressed to approximately four months. This convergence reflects rapid advancements in open-source iterations, ranging from Llama 2-70B to recent releases like GLM 5.2 and Kimi K2.6, which are now approaching the capabilities of closed-source leaders such as GPT-5.5 Pro.

This trajectory suggests that the competitive moat previously held by closed-source giants is rapidly eroding. Deutscher projects that within six months, open-source models will achieve intelligence levels comparable to Claude Fable, available for unrestricted public download. Consequently, this shift threatens to fundamentally reshape the AI business landscape, intensifying competition over computing power and diminishing the value of proprietary model exclusivity.
