This restriction in field of endeavour is against the common Open Source Initiative definition of open source. How about we call them open weight models instead?" Link

  • JJ: "@sytses I like this proposal for a few key reasons: 1) open source and free software were invented to be applied to source code ... neural net weights are fundamentally NOT source code 2) this would avoid "open source washing" 3) standardizing on Open Weights (OW) models (ie OW LLMs)...

  • Wei Lien Dang: "Do GitHub stars matter? The results are in! Think of stars as a measure of relative mindshare, like an OSS marketing share of voice. It's best to compare stars to peer projects or w/in the same category. For benchmarks, here's a dataset from 60+ co's:

  • Didier Lopes: "So excited about OpenBB. You'd think that the excitement level goes down over time, but it's actually the opposite. Talking with professionals in the industry and how they perceive what we are doing is still mind blowing. OpenBB is bigger than all of us." Link
