Sakana: BETTER Than Fable 5?

Sakana Fugu Ultra vs Fusion vs Claude Opus 4.8 (42 Builds + Goldie Bench): Is It Fable 5-Level?The video reviews Sakana Fugu Ultra after several days of release, testing whether it matches “Fable 5-level intelligence” claims by running 42 builds using the same prompts across Fugu Ultra, Fusion (OpenRouter), and Claude Opus 4.8, plus Goldie Bench leaderboard comparisons. The script explains Fugu as a multi-agent orchestration system that fuses outputs from closed and open models, contrasting it with Fusion’s pay-per-token API pricing versus Fugu’s flat subscription with token limits and frequent lockouts, slow responses, and one-shot workflows. Side-by-side build demos (solar system, runner, fireworks, dungeon crawler, open world) show mixed results but generally stronger outputs from Fugu Ultra, with Fusion often close or better on some examples and Opus 4.8 frequently failing. Benchmarks cited include Fugu leading LiveCode Bench but trailing Fable 5 on SWE Bench Pro and Terminal Bench, and a brief comparison of Fugu Ultra vs cheaper Fugu Mini. The episode ends by promoting the AI Profit Boardroom agent operating system integrating Sakana, Fusion, Claude, and other tools.00:00 [https://www.youtube.com/watch?v=uhcWUS4f0vc] Fugu Ultra Overview00:45 [https://www.youtube.com/watch?v=uhcWUS4f0vc&t=45s] Testing Setup and Limits01:26 [https://www.youtube.com/watch?v=uhcWUS4f0vc&t=86s] Models and Method02:02 [https://www.youtube.com/watch?v=uhcWUS4f0vc&t=122s] What Is Fugu03:00 [https://www.youtube.com/watch?v=uhcWUS4f0vc&t=180s] Leaderboard and Pricing04:12 [https://www.youtube.com/watch?v=uhcWUS4f0vc&t=252s] Build Demos Part 106:21 [https://www.youtube.com/watch?v=uhcWUS4f0vc&t=381s] Build Demos Part 208:33 [https://www.youtube.com/watch?v=uhcWUS4f0vc&t=513s] Open World Comparison09:23 [https://www.youtube.com/watch?v=uhcWUS4f0vc&t=563s] Benchmark Breakdown10:16 [https://www.youtube.com/watch?v=uhcWUS4f0vc&t=616s] Fugu Mini vs Ultra12:03 [https://www.youtube.com/watch?v=uhcWUS4f0vc&t=723s] Final Verdict12:13 [https://www.youtube.com/watch?v=uhcWUS4f0vc&t=733s] Boardroom and Outro
