Sakana: Fugu Max

Our take

AI-assisted analysis based on the sources below. Suitability is an editorial assessment; test it on your own workload.

OpenRouter's catalog describes sakana/fugu-max as Sakana AI's cost-performance entry in the Fugu family and as part of a learned multi-agent orchestration system rather than a standalone monolithic model. The listing reports text, image, and file inputs with text output, a one-million-token context window, mandatory reasoning that defaults to high effort, and support for tools, structured outputs, and web-search options. These are source-reported capabilities; no independent model card or measured benchmark results were included in this source pack.[1]

Strengths

  • Catalog-reported multimodal input covers text, images, and files, with text-only output.[1]
  • The listing reports a one-million-token context window, potentially useful for long prompts.[1]
  • Mandatory reasoning defaults to high effort, with max and xhigh also listed; tools, structured outputs, and web-search options are supported.[1]

Limitations

  • Only OpenRouter catalog data was supplied; an independent model card was not available in this source pack.[1]
  • No benchmark measurements were included, so accuracy, latency, reliability, and the claimed cost-performance balance require workload validation.[1]
  • The knowledge cutoff is not reported, and reasoning is mandatory with no listed low-effort option.[1]

Where to use it

  • Evaluate for long-document or multi-file question answering when text-only responses are sufficient.[1]
  • Consider for agent-style workflows that require tool calls or structured outputs.[1]
  • Test for image-and-file analysis tasks where always-on, higher-effort reasoning is acceptable.[1]

Tasks and capabilities

A grade appears only where the source supplies a matching measurement for that task, the model is active and the cohort holds at least 10 comparable models. The capability column lists facts the source declares — supported formats, reasoning and tool parameters — which are not measured quality.

How grades work

Each letter grade compares a model only against other models scored by the same source and metric in the current snapshot. S means the top 10%, A the next 20%, B the next 30%, C the rest. Models without a published measurement are shown as not rated — a supported format alone never implies measured quality.

  • S — S — top 10% of the cohort
  • A — A — next 20% of the cohort
  • B — B — next 30% of the cohort
  • C — C — below the B band
