- The post argues that **Kimi-K3** is still not better than **Fable**, but is clearly closing the gap. - It says the open-source frontier is now only about **1.5 months behind** closed models, based on the **Artificial Analysis** chart shown in the image. - The chart compares the evolution of **closed** vs **open-weights** frontier models and highlights the rapid growth of recent open models. - The author also points out that the biggest open models are getting larger, with **Kimi-K3** reportedly nearing **3T parameters**, so it is far from something that runs comfortably on a laptop. - The image also raises a question about **Google’s** relative pace since **Gemini 3 Pro** last November.
