What is Fugu Mini?

Fugu Mini is the Sakana AI frontier model with a Single-model variant of Sakana's Fugu — no panel orchestration. Same API endpoint, much faster per call. context window, released 2026-06-15. Tagline: Fugu's fast mini variant — single model, no panel, ~3 min per build.. Official source: sakana.ai.

Pricing detail. The non-Ultra `fugu` model on Sakana's API. Sakana describes it as 'Fast mini model optimized for low latency yet high quality responses.' Crucially: zero orchestration tokens per call (vs Ultra's panel of thousands). Returns in ~3 min instead of 6-15 min and doesn't time out on heavy prompts.

How I use it inside the Agent OS. Dispatched from Agent OS as the fast Sakana lane. Bench scored by Claude judge against the same 42 prompts.

What I built with Fugu Mini

Every model on Goldie Bench gets the same fixed prompt set — one shot, single HTML file out — and I score the result 0–10 inside the Agent Operating System. Here's what Fugu Mini shipped on the bench: 37 one-shot demos across Single-model variant of Sakana's Fugu — no panel orchestration. Same API endpoint, much faster per call. of context. Of those, 36 are scored against the field with my honest 0–10 from the source guides at agentos.guide.

Strengths

  • Zero panel orchestration — much lower latency than Ultra
  • Same Sakana subscription, no extra cost
  • Doesn't time out on heavy game/3D prompts where Ultra stalls

Trade-offs

  • Single model only — no ensemble verdict
  • Newer than Ultra — less calibration / verification

Best for

  • Agent loops where latency matters more than panel consensus
  • Quick first-drafts you'll refine downstream
  • Filling out a bench when Ultra is timing out
