Ask HN: Anyone using Jev / other decision models? What for?

The decision model / System One model pattern was pioneered by Jev a month ago. Since then OpenAI shipped their version and ther have been dozens of open weight implementations too.

Are you using any of these in production yet? If so, what are you using them for?

    Made a Jev-based daily guessing game that's like a crossover between Wavelength and Family Feud (or Family Fortunes if you're from the UK or Ireland).

    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

    My one experiment with these models so far hasn't worked. I was hoping I could use them to find my "best" photos - most aesthetically pleasing, best composed, etc.

    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.

      Have you tried giving these models questions about coin flips and dice rolls? Or happen to catch any of the Jev plays Pokemon?

      It completely undermines any trust I have in their outputs. Comparing to a little llm is amusing, coins are still 50/50 with 100% confidence for them. I didn't follow up with any questions about landing on the side.
