If Mozilla must throw money at AI, this is the way to go... I guess. Ente is trying to build a Google Photos replacement that translates image contents into searchable text while being fully end to end encrypted (read: as private as it gets), after all. Ente also allows you to fully self-host, so you can get these benefits without even trusting their servers.
Out of the $65 million Mozilla has committed to throwing at for-profit and AI companies (that's roughly 9.4 Mitchell Baker Salaries), $100,000 is a drop in the bucket, only 1.44% of the size of a Mitchell Baker Salary.
I remain skeptical about Mozilla's commitment to "open source AI models" when I haven't seen a single blob of AI data released that is reproducible or open source. They are black boxes, and black boxes so closed that not even the people that created them could tell you what's inside of them (unless we count the blood, sweat, and tears of the underpaid workers behind it).
Full disclosure: I am a paying Ente subscriber
