It's great how we went from "wait.. this model is too powerful to open source" to everyone trying to shove down their 1% improved model down the throats of developers
Training models isn't cheap. Individuals can't easily do this, unlike software development. So we need companies to do this for the foreseeable future.
To me that's what closed source companies (MSFT, Google) are doing as they try to force AI assistants into every corner of their product. (If LinkedIn tries one more time to push their crappy AI upgrade, I'm going to scream...)
