Seeking someone’s irl name based on seeing them in a photo is fucked up, regardless of platform.
You’re working backwards, you seem to know this person is an influencer personality or something, and are assuming they’d therefore be fine with people seeking them out. The above comment (imo), and my comment are working from the photo only. As such, it’s fucked up.
Training an existing model on a specific set of new data is known as “fine tuning”.
A base model has broad world knowledge and the ability to generate outputs of things it hasn’t specifically seen, but a tuned model will provide “better” (fucking yuck to even write it) results.
The closer your training data is to your desired result, the better.
