In this video, I'll be telling you about Sakana Fugu, a new multi-agent orchestration system that claims to be competitive with models like Fable 5 and Mythos Preview. I’ll go over what Fugu actually is, how its benchmarks compare, what the pricing looks like, and how it performed in my own coding and visual generation tests.

Key Takeaways:

🐡 Sakana Fugu is not a normal foundation model, but a learned router and multi-agent orchestration system.
⚡ Fugu comes in two versions: the faster everyday Fugu and the more performance-focused Fugu Ultra.
📊 Fugu Ultra performs well on benchmarks like Terminal Bench, LiveCodeBench, GPQA Diamond, and CharXiv Reasoning.
⚠️ Despite strong benchmark numbers, it still loses clearly to Fable 5 on tests like SWE Bench Pro and Humanity’s Last Exam.
💸 Fugu Ultra looks cheaper than Fable on paper, but orchestration tokens can increase the real usage cost.
🧪 In practical coding tests, the outputs were mixed, with weak results in Three.js tasks, simulators, SVG generation, and local workflow setup.
🤔 Overall, Fugu feels more like an interesting AI router than a true Fable replacement right now.
