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

June 21 — Michael Saylor, founder of Strategy, took to social media today to urge Bitcoin holders to stay unified. Saylor noted the Bitcoin community aligns on roughly 99% of core issues, advising that the remaining 1% of disagreements should not lead to division. He emphasized that the vast majority of global capital has yet to enter the Bitcoin network, pointing out this historic opportunity is far more significant than internal community debates. According to Saylor, any internal split amid such a massive shared interest would be a waste of this pivotal chance.
