Analysis: The gap between open-source AI and cutting-edge models has shrunk from 12 months to 4 months. By the end of the year, top-tier intelligence may be available for free download.

On June 21st, crypto and tech analyst Miles Deutscher cited data from Epoch AI’s Capability Index, showing the gap in capabilities between open-source AI models and top closed-source large models is shrinking rapidly. Two years ago, this gap stood at roughly 12 months—but it’s now narrowed to around 4 months. From a development perspective, open-source models have advanced from models like Llama 2-70B to newer releases including GLM 5.2 and Kimi K2.6. Meanwhile, closed-source frontier models have evolved to the scale of GPT-5.5 Pro. At the current pace of progress, Deutscher predicts a top-tier AI matching the capability of Anthropic’s Claude Fable model will be freely available for public download in open-source form in roughly another 6 months. This trend means the capability advantage once seen as a core moat for closed-source tech giants is fading fast. The rise of the open-source ecosystem could profoundly reshape the AI business landscape and global competition around computing power.
