Four years after analyzing the open-source ML ecosystem, I revisited the topic focusing on foundation models. The updated list of open-source AI repositories is hosted at llama-police, updated every 6 hours. With 118K results for GPT alone, I limited my search to repos with 500+ stars, resulting in 896 repositories. Highlighting AI stack layers – infrastructure, model development, app development, and apps – I observed significant growth in 2023, particularly in AI engineering and applications. Noteworthy is the rise of one-person billion-dollar companies in the AI space. China’s open-source ecosystem diverges from the Western one, with six top accounts originating from China. Anecdotal discussions suggest a shift away from generative AI towards more grounded AI topics.
