What's FOSS-AI? A model everyone can download and use for free? Or in the OSS spirit that everything need to be open and without discrimination of use, aka OSS training data corpus and no AUP attached?
Or you mean the inference engine running those models?
Agreed, but there have been big projects that have been open source. I can imagine* an AI (LLM) being developed fully FOSS. It would be rare, but I can see it happening if a big foundation got behind it. Maybe Mozilla, or another that tries to keep the spirit of their mission statement.
*Imagine: I'm not too familar with all of the current, public, and free models out there, just a few. This was just me making a hopeful guess about if it might be actually happening now.
