License tag
The model is based on an open source version of StableLM under the CC BY-SA 4.0 license.
While I don't think models are (or should be) copyrightable, we'd better act as if they are, which is why licensing is being dealt with to begin with.
While the CC BY-SA 4.0 is a free and open license, it is (unlike, for example, Apache 2.0, MIT or CC BY 4.0) a copyleft license.
The model cart asserts that the license for this model is CC BY-SA 4.0, but the tag still incorrectly states "apache-2.0". It's the latter that should be fixed.
It must be noted that while Pythia versions of Open Assistant are purposefully under non-copyleft licenses, StableLM-based ones are under a copyleft license. This is ok, it's just important to be clear with those who may use the model.
(Note: if assets in the dataset are also derived by assets under Apache 2.0, this raises the question of compatibility between the two licenses. If they are directly compatible, CC BY-SA 4.0 is fine for this project. If not, GPL 3.0 would solve the issue as both licenses are compatible with it).
Should be fixed now
