Meta's model can depict public profiles
The setting is on by default. Anyone with a public profile has to opt out in their settings, and a private profile is not affected.
A tagged person is not notified when someone creates content with their likeness, so they may only find out when a friend sends them an image.
The image model came out this week from Meta's superintelligence lab and is the company's first. It ranks number two among image models, just behind ChatGPT's Image Gen 2. A companion video model sits just behind Seed Dance.
Why do opt-out defaults change behavior?
A 2003 study in Science by Eric Johnson and Daniel Goldstein compared organ donor consent rates across European countries. In countries where people must opt out, such as Austria, effective consent was close to 100 percent. In countries where people must opt in, such as Germany, it was about 12 percent.
How are image models ranked against each other?
Leaderboards such as LMArena, formerly Chatbot Arena, show voters two anonymous outputs and ask which is better. Ratings are computed from those votes using Elo-style or Bradley-Terry statistics. The Elo system was devised by physicist Arpad Elo for chess and adopted by the international chess federation FIDE in 1970.
How do image models reproduce a person's likeness?
A technique called DreamBooth, from Google Research in 2022, fine-tuned an image model on as few as three to five photos of a subject. Newer methods skip the fine-tuning step by encoding a reference photo into an embedding that is fed in at generation time. The IP-Adapter method, published in 2023, works this way. Both aim to hold identity features such as face shape fixed while the rest of the image changes.
