Sakana Marlin is the product Sakana AI shipped before Fugu — its first commercial product, launched June 15, 2026 — and it’s a different animal entirely: not a model you call per token, but an autonomous strategy-research agent that runs…
Sakana Namazu is the other Sakana model — not part of the Fugu family, not an orchestrator, and easy to misunderstand because of both. It’s a Japanese-specialized LLM API with built-in web search and code execution, priced at a fraction…
This is an independent, third-party company profile compiled by fugu-ai.com. We have no affiliation with Sakana AI; every claim below traces to Sakana’s own published pages and dated announcements, re-checked on August 19, 2026. Sakana AI is a Tokyo-based AI…

Fugu Ultra is what Sakana AI ships when the answer matters more than the invoice. Where base Fugu balances performance against latency, Ultra draws on a deeper pool of expert agents and routes between one and three of them per…
Fugu’s installers are unusually well-behaved — dry-run modes, automatic backups, config rollback on parse failure — but things still go wrong: half-finished installs, keys that won’t authenticate, launchers that aren’t found, models that don’t appear. This is the failure catalog…

The Codex integration is the most complete way to run Sakana Fugu in a coding agent: a launcher that keeps your config current, a version-pinned Codex known to work with Fugu’s configs, and a real backup system for everything it…
Fugu turns Claude Code into a front end for Sakana’s multi-agent system: same terminal workflow you already know, but the model behind it is an orchestrator commanding a pool of frontier models. Setup takes one command — or five environment…
