Fugu vs Fusion: The Fable 5 Test

Sakana Fugu Ultra vs OpenRouter Fusion: Side-by-Side Tests (Beating Fable 5?)The video compares two new “panel” APIs—Sakana’s Fugu (Ultra and Mini) and OpenRouter Fusion—both claiming benchmark performance above Fable 5, by testing them side by side on visual/code generations like a landing page, raycaster maze, living spiral galaxy, inner solar system, and other simulations. In these examples, Fugu Ultra consistently produces the best-looking, smoothest outputs, Fusion is generally second, and Fugu Mini is faster but more variable and sometimes buggy. The script notes practical tradeoffs: Sakana/Fugu is cheaper with a flat plan but is heavily limited by daily generation/time caps and token limits, while Fusion is easier to use via API but costs per token. Both are one-prompt systems with long waits, and both are integrated into the creator’s Agent operating system and AI Profit Boardroom community.00:00 Sakana vs Fusion Intro00:32 How Panel APIs Work01:35 Landing Page Showdown02:17 Maze and Galaxy Tests03:42 Solar System Quality Gap04:10 Limits Pricing and Workflow06:09 Fusion Open World Example07:07 Fugu Mini Results08:00 Liquid Simulation Comparison08:55 Final Rankings and Tradeoffs09:35 Agent OS and Community Plug11:12 Wrap Up
