This is insane. We just got ANOTHER Mythos-level intelligence LLM. This model operates like no other AI we've ever seen, and it's actually mind-blowing. Fugu isn't just one model. It's a model trained to orchestrate OTHER models. In Sakana's own words: "a language model trained to call various LLMs in an agent pool, including instances of itself recursively." What that actually means: When you send a task, Fugu doesn't answer directly. It decides when to delegate → how the agents should communicate → how to combine their outputs into one reliable answer. It assigns roles - Thinker, Worker, and Verifier to delegate work across coding, math, reasoning, and knowledge tasks. Fugu Ultra scores 73.7 on SWE-Bench Pro and stands shoulder-to-shoulder with Fable 5. One engineer reported it surfaced over twenty issues in code review compared to the typical three from other tools. This is a completely different bet on how Frontier Intelligence gets built. We're so early.(Miles Deutscher)
