The Future of Open Source AI

Open source AI is positioned to be more competitive than closed models due to inherent flexibility and the potential for innovation within the ecosystem. Tim Detmers expresses skepticism regarding the continuation of open-source releases from major players, suggesting that forthcoming models may lean towards being proprietary. He believes that the end of the open-source model era could inadvertently stimulate development in the community. The adaptability and collaborative nature of open-source practices could, therefore, pave the way for sustainable advancements.

Tim Dettmers does not need an introduction for most people building open-source AI. If you are part of that minority, you’re in for a treat. Tim is the lead developer behind most of the open-source tools for quantization: QLoRA, bitsandbytes, 4 and 8 bit inference, and plenty more. He recently finished his Ph.D. at the University of Washington, is now a researcher at the Allen Institute for AI, and is starting as a professor at Carnegie Mellon University in fall of 2025.

Tim is a joy to talk to. He thinks independently on all the AI issues of today, bringing new perspectives that challenge the status quo. At the same time, he’s sincere and very helpful to work with, working hard to uplift those around him and the academic community. There’s a reason he’s so loved in the open-source AI community.

Find more about Tim on his Twitter or Google Scholar. He also has a great blog where he talks about things like which GPUs to buy and which grad school to choose.
