We’ve been thrilled by the reception to the Fugu model family. Thanks to everyone who tried it, shared feedback, and trusted Fugu with real, complex work.
Today, we are thrilled to announce the next evolution of our orchestration engine: Fugu-Ultra v1.1 🐡
**👉 **Sakana Fugu By dynamically orchestrating the latest frontier models, we pushed performance up by as much as 7.9 points. We are now beating leading models like Fable 5 in complex coding and reasoning tasks, without even having Fable in our agent pool.
Collective intelligence is the future!
Fugu-Ultra v1.1: The Frontier Keeps Moving #
Fugu-Ultra is now upgraded to incorporate the latest frontier models. Our latest Fugu-Ultra v1.1 delivers stronger performance across every benchmark we track.
This orchestration upgrade resulted in gains of up to 7.9 points over v1.0, with particularly strong results on ProgramBench and Terminal Bench 2.1. Fugu-Ultra v1.1 is demonstrably more capable across coding, agentic tasks, and advanced reasoning.
The frontier keeps moving, and Fugu keeps getting better. Crucially, this massive leap in reasoning capabilities is available today at the same price as Fugu-Ultra v1.0.
Announcing the Claude Code-compatible interface for Fugu #
Since launch, Fugu models have been adopted by platforms including OpenRouter and Vercel. We’ve loved seeing developers use them across coding agents, research workflows, automation, and applications we never anticipated.
Today, we’re making Fugu more accessible again with Claude Code-compatible endpoints for Sakana Fugu.
You can now bring Fugu’s multi-agent intelligence directly into Claude Code. This puts a dynamically coordinated team of frontier models to work inside the coding workflow you already know and love. Instead of relying on a single model to write, debug, and execute your code, you can now orchestrate a diverse pool of state-of-the-art models directly from your terminal.
Put the whole school of fish to work on your next task 🐟
