On Dec 31 2024 I will run this prompt in Midjourney five times with random seeds: "a portrait of a smiling man and his frowning, sad wife"

I will run it with all the default options, aspect ratio 3:2, and the most advanced general model a paid subscriber can get under 100$ a month. If at least 50% of the resulting images successfully make the man look happy and the wife look unhappy, the claim resolves True.

Today the success rate is 0%. Five images generated with these settings are inlined below. Currently, Midjourney doesn't track individual subjects clearly in this way.

Image from 12/20/2023, still not able to distinguish the people's facial expressions.
