unpopular opinion: gemini is a pretty great model most current baseline models are actually perfectly fine for 99% of everyday work. not everyone needs a state-of-the-art coding model to get things done.
We just pushed a big update to Sakana Chat Free to use: chat.sakana.ai A big motivation for this release is getting people in Japan, especially kids, excited about software development. Vibe-coding turns Kanji & Math drills during the summer break into fun games they can actually build themselves.
Incredibly proud of the Sakana AI team. We have developed an orchestration model right here out of Japan that achieves state-of-the-art performance on real-world cybersecurity benchmarks! 🎌 sakana.ai/fugu-cyber-r...
Today, things have come full circle. We are now trying to use modern VLMs and frontier LLM agents within open-ended exploration algorithms. We want to see if we can finally computationally derive the underlying mechanics of human creativity: serendipity, memory, exploration, and novelty search.
I am incredibly proud of our Tokyo team for shipping this. By orchestrating the world’s models, we are delivering the resilient blueprint required for AI sovereignty. Read our full vision and results here: sakana.ai/fugu-release 🐡
Collective intelligence is the practical hedge against this concentration of power. Fugu simply routes around vendor restrictions by relying on an entirely swappable agent pool.
But Fugu is about more than just performance. I believe that Orchestration Models are the next frontier, beyond bigger models. Relying on a single company’s model for national infrastructure is a massive risk. As recent export controls have shown, access to top models can disappear overnight.
Reproducing all of Jürgen Schmidhuber’s papers (1990-2025) using an AI coding assistant. Cool project by Yaroslav! It even reproduced the “World Models” paper by me and Schmidhuber (2018) using a toy environment, with a full VAE + RNN world model implementation. Project: github.com/cybertronai/...
How do we make LLMs faster and lighter? Don’t force the GPU to adapt to sparsity. Reshape the sparsity to fit the GPU! ⚡️ Paper: arxiv.org/abs/2603.23198 Blog: pub.sakana.ai/sparser-fast... Code: github.com/SakanaAI/spa...
Excited to share Sakana AI’s new #ICML2026 paper in collaboration with NVIDIA: "Sparser, Faster, Lighter Transformer Language Models" arxiv.org/abs/2603.23198 This work introduces new open-source GPU kernels and data formats for faster inference and training of sparse transformer LLMs: 🧵 Thread 👇
Along with our TRINITY paper which we announced earlier, this work also powers our new multi-agent system: Sakana Fugu: sakana.ai/fugu-beta 🐡
What surprised me most was how it dynamically adapts. For simple factual questions, it just queries one model. But for hard coding problems, it autonomously spins up a whole pipeline of planners, coders, and verifiers.
It learns to dynamically assign Thinker, Worker, and Verifier roles to a pool of frontier models—combining their strengths to hit SOTA on LiveCodeBench. This research is part of the engine powering our new product: Sakana Fugu sakana.ai/fugu-beta/ 🐡
One of my favorite things about Fugu is the test-time scaling. When allowed to call itself recursively, it reads its own prior output and spins up corrective workflows on the fly to fix its mistakes. We are finally opening up the API for beta testers to try it out. sakana.ai/fugu-beta

Instead of interacting with a real operating system, these models can take in user actions like keystrokes and mouse clicks alongside previous screen pixels to predict and generate the next video frames.
A “Neural Computer” is built by adapting video generation architectures to train a World Model of an actual computer that can directly simulate a computer interface. Paper: arxiv.org/abs/2604.06425 Code: github.com/metauto-ai/N... Cool work led by Mingchen Zhuge et al. from Schmidhuber’s lab!
I truly believe AI will forever change the landscape of how scientific discoveries and scientific progress are made.
Our journey at Sakana AI is just getting started. We are looking for people to help us pioneer the next generation of AI—building from Japan to the world. Join us: sakana.ai/careers
Reminded me of my older NeurIPS 2021 paper, where we removed the positional encoding entirely, and by doing so, an agent can process an arbitrarily long list of noisy, sensory inputs, in an arbitrary order. I even made a fun browser demo to play with the agent back then: attentionneuron.github.io
Software Engineering as a profession will continue to fundamentally change in 2026. Humans will need to learn to co-adapt to this evolving “alien technology” which comes with no real manual, and figure out how to operate it. What a time to be alive ✨ twitter.com/karpathy/sta...
“Why AGI Will Not Happen” by Tim Dettmers. timdettmers.com/2025/12/10/w... This essay is worth reading. Discusses diminishing returns (and risks) of scaling. The contrast between West and East: “Winner takes all” approach of building the biggest thing vs a long-term focus on practicality.
