"Open weights" is a correction that arose out of calling models whose weights were released under open-source licenses "open-source" before the OSI sold out. These companies trying to dilute the polite correction just like they tried to dilute "open-source" only reinforces my point.

There was an attempt to create an analogue of the OSI's Open-Source Definition that acknowledged the problems of merely releasing weights as "open-source". That project seems to have largely failed or fizzled, and "open weight" has come to be used mostly as a way of acknowledging that only the weights have been released under open-source terms.

This model of Meta's fails even that dramatically weakened standard.

This is just a series of dilutions by which giant corporations are trying (and apparently succeeding here on "hacker" news) to trade on the cachet of commitments they don't actually hold.

I mostly agree, but again, You said "Open-weights means weights are released under an open-source license" and I asked "According to who?"

"Open weights" is for the most part a term that is meaningless besides being technically able to run it on your own hardware.

I don't think we have a proper term for what you are reaching for, and proper open-source models (training, training-data, etc. being fully open) are scarce.
