What I built with Fugu Mini

Every model on Goldie Bench gets the same fixed prompt set — one shot, single HTML file out — and I score the result 0–10 inside the Agent Operating System. Here's what Fugu Mini shipped on the bench: 37 one-shot demos across Single-model variant of Sakana's Fugu — no panel orchestration. Same API endpoint, much faster per call. of context.

Strengths

Zero panel orchestration — much lower latency than Ultra
Same Sakana subscription, no extra cost
Doesn't time out on heavy game/3D prompts where Ultra stalls

Trade-offs

Single model only — no ensemble verdict
Newer than Ultra — less calibration / verification

Best for

Agent loops where latency matters more than panel consensus
Quick first-drafts you'll refine downstream
Filling out a bench when Ultra is timing out
