Frequently Asked Questions
- What should I know about Fugu Ultra v1.0?
- Sakana AI develops this multi-model orchestration system in Japan. Results measure the coordinated model pool, not a standalone base model. The IQ estimate uses six Sakana-reported June 2026 results across three dimensions, with conservative estimates for missing coverage. These are provider evaluations, not independent Artificial Analysis or Vals measurements. These scores describe the separately available fugu-ultra-v1.0 (formerly fugu-ultra-20260615). The default fugu-ultra API now points to v2.0; no v1.1 or v2.0 scores are implied. Standard pricing is $5 input and $30 output per million tokens; above 272K context it is $10/$45. Internal orchestration tokens are billed too. Effective cost is estimated, without measured Fugu orchestration usage.
