The verdict
The higher-performance tier of Sakana AI's learned multi-agent orchestration system, at $5 / $30 per 1M tokens. Like Fugu Max it routes work across a team of agents rather than answering with one model. Artificial Analysis has not benchmarked it, so it carries no Intelligence Index here — the rating shown is a tier estimate, not a measurement.
A concrete example: sending 100,000 input tokens and getting back 20,000 output tokens with Fugu Ultra v2 costs about $1.10 at current prices.
Who is Fugu Ultra v2 for?
Fugu Ultra v2 is the higher-performance member of Sakana AI's Fugu family — a learned multi-agent orchestration system that assembles a team of agents to work a problem, rather than scaling a single model. At $5 per 1M input and $30 per 1M output it is priced in premium territory, and above 272k prompt tokens the rate doubles.
As with Fugu Max, the limitation on this site is data: there is no Artificial Analysis Intelligence Index for it, so it cannot be ranked on intelligence per dollar, and the figure shown is a tier-based estimate. If you are evaluating it, do so against its own published benchmarks — we have kept the entry so the catalogue is complete, not because we can vouch for its ranking.
Strengths & weaknesses
- Strength: Highest-capacity Fugu tier for hard multi-step tasks
- Best for: Agentic, Quality
- Weakness: Unbenchmarked on Artificial Analysis; premium pricing without a verified index.
