Sakana Fugu surprisingly performed near GLM 5.2 level but 17× more expensive!
We gave the same prompt to 4 models: build a complete live Trader Desk with both frontend and backend components, real-time market data fetched from external APIs for 8 symbols, and a custom dark-theme UI.
Outputs:
Fugu Ultra — 22,225 t, $0.51
Opus 4.8 — 15,802 t, $0.31
GPT-5.5 — 11,474 t, $0.26
GLM 5.2 — 13,677 t, $0.03
Fugu created the most polished and feature-rich trading desk in the run. GLM 5.2 was very close behind, with a similarly complete multi-panel interface and live data, but at a much lower cost. Opus and GPT also performed well, delivering solid results with a better balance between quality and cost
