Space Bunny on OpenRouter: how should you actually vet a model for agent workflows?
Hot-Purchase-3738 · reddit · 2026-09-25
A new anonymous model, Space Bunny, is on OpenRouter, and the poster skips the who-made-it guessing to focus on evaluating any model for real agent work.
His point: chat models can be judged on one or two answers, but agents must hold constraints across steps, use tools consistently, recover from mistakes, and stay on goal.
His proposed pass/fail test:
- A small stateful task with explicit rules, several tool calls, and one injected failure midway — does the model recover without redoing finished work or dropping earlier constraints?
- Run the same task multiple times; a model that nails it once then collapses is less trustworthy than a predictable one.
Signals to watch: asking when info is missing, avoiding repeated tool calls, recovering from failed commands, keeping constraints as context grows, not creating extra work while "fixing" things, and how much supervision is needed before letting it run 20-30 minutes unattended.
