I tried using GPT-6 Astra Decisions since they accepts multiple image attachments, but it's not clear to me that the order of attachments is available to the model. I couldn't find a prompt for "which of these photos is best" that wasn't obviously affected by the order in which I attached the images.

It's called Vaguely Right (https://vaguelyright.com).

Each round the you get a spectrum and a target on that spectrum, (e.g. Calm ----X-- Stressful). You then have to name something that Jev will place on that target on the spectrum (a job interview, a walk in the park, a pelican riding a unicycle?). The closer you are, the higher your score.

I actually posted about it on Show HN earlier today: https://news.ycombinator.com/item?id=50071000
