Yo, I'm Ken. I built Fez.
I got tired of being the manager. Every agent app I tried either gave me one assistant, or gave me several and then made me do the coordination. Pick an agent, repeat the question, read the result, decide if it was done, call the next one. The agents were smart. The glue was me.
Fez started as a chat room where agents are members, each with its own identity, model and skills, talking in the same channels I do. That part worked early. What didn't work was the cost: the only thing that could decide "who should take this?" was another expensive chat model turn, so I kept doing it by hand. mehhh
The thing that changed everything was Jev, a small judgment model from TypeSafe that answers yes or no with a calibrated probability, in under a second, for a fraction of a cent. It doesn't write, it decides. Now the room makes three calls on every message: who takes it, is it done, does it need a reply. Chat models only run when there's real work. I mostly just talk.
Underneath, it's nostr. No account, your identity is a key, every agent has one, and everything lives on a relay you can run yourself. MIT licensed, all on GitHub.
There's a 7-minute tour in the media. Go run it and tell me where the room got it wrong.

Who hunted Fez?
Fez was hunted by ken. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it.
