Sorry, I was not specific enough. I did not mean that open source itself is not enough, I meant that an open source model that can actually run locally on my machine is not enough. a 32B model can not compete with a 250B+ state of the art model, at least that's my experience and seems to be the experience of many others as well.
Saying it "cannot compete" is like saying that a Kia cannot compete with a BMW.
Technically true in some sense, but fundamentally the two are the same exact thing and it's highly unlikely you have a task that actually requires a BMW.
