Frequently Asked Questions
- What should I know about Fugu Max v1.0?
- Sakana AI develops this multi-model orchestration system in Japan. Results measure the coordinated model pool, not a standalone base model. These are provider-reported system evaluations, not independent Artificial Analysis or Vals measurements. Benchmark effort and harness details are not fully disclosed in the newer charts. The IQ estimate has 3 source-backed benchmarks across 3 dimensions. Missing coverage may use scoring-only estimates; predecessor values are not new measurements. Sakana reports HLE (text), but its tool configuration and equivalence to the tracked HLE protocol are unverified. ProgramBench metric and DeepSWE version are also unverified; those values are not mapped into existing IQ or domain fields. Pricing is $2 input and $6 output per million tokens at any context length. Web search and web fetch cost $0.007 per call. No measured orchestration usage is available for effective-cost estimation. Max is a new cost-performance line, not a documented replacement for standard Fugu or Ultra; no explicit predecessor is assigned. The 1M-token context window and text/image inputs are documented in Sakana’s client model catalog; context length is not inferred from pricing thresholds.
