Fugu Ultra - access through LLMTR
Fugu Ultra is Sakana AI's OpenAI-compatible multi-agent reasoning model, currently serving v2.0. It spreads work across a pool of expert agents rather than a single model, prioritising answer quality on hard coding, security analysis, scientific research, and long-context synthesis work. It is the option for jobs where quality outranks cost; teams that want the same agent approach at a lower price point should look at the Fugu Max row.
