Real head-to-head · same prompt, one shot
Fugu Mini vs Kimi K2.7 · Quality
Fugu's fast mini variant — single model, no panel, ~3 min per build. vs Quality mode — deepest thinking, best output.
What I tested — same prompt, two models
I run the same fixed prompt set through every new model the day it drops — same string, one shot, single HTML file out — and I score the result 0–10 on whether it ran, how close it hit the brief, and how good it looked. Below is what came out when I gave the exact same prompts to Fugu Mini and Kimi K2.7 · Quality, side by side, on 3 shared tasks inside the Agent Operating System.
Both models were given identical prompts inside the Agent Operating System — no help, no iteration, no "best of N" tricks. I run each prompt once, save the HTML file the model produces, and score it 0–10 on whether it ran, how close it hit the brief, and how good it looked. The scoring is mine. The verdicts below are pulled from my source comparison guides at agentos.guide where I publish every score and the reasoning behind it.
Fugu Mini · Dispatched from Agent OS as the fast Sakana lane. Bench scored by Claude judge against the same 42 prompts.
Kimi K2.7 · Quality · Reserved for one-shot builds where the output is the deliverable — polish over speed.

The verdict — which should you pick?
Not enough scored shared tasks yet for a head-to-head average. The live demos for both are on the matrix above — play them and form your own opinion.
If you only run one of these inside your stack, the head-to-head average above is the call. If you can run both, my honest play is to wire Fugu Mini and Kimi K2.7 · Quality both into the Agent Operating System and dispatch each from the kanban by task type — agent loops where latency matters more than panel consensus → Fugu Mini, one-shot games and sims where polish matters → Kimi K2.7 · Quality. That's the same setup I run for the 3,600+ founders inside the AI Profit Boardroom.
