「How Competition is Stifling AI Breakthroughs」 Sakana AI共同創業者 Llion Jones のTED AIトークが公開されました。目標を定めすぎないオープンエンドな研究がブレークスルーを生む理由、Transformerの成功が業界にもたらした状況、それを乗り越える次の構想と成果を語りました。 www.ted.com/talks/llion_...

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

I founded Sakana AI after my time at Google, so it is incredibly meaningful to be able to partner with them now. It feels like a special connection to be working together again to advance the AI ecosystem in Japan. sakana.ai/google#en

Our work on The AI Scientist and ALE-Agent has already shown the power of these models. Now, we are scaling reliable AI in mission-critical sectors like finance and government to ensure the highest security and data sovereignty. Full details: sakana.ai/google#en

We are thrilled to announce a strategic partnership with Google! Google is also making a financial investment in Sakana AI to strengthen this collaboration. We are combining Google’s world-class products like Gemini and Gemma with our agile R&D to accelerate automated scientific discovery.

We just published an unofficial guide on what we look for when interviewing research candidates at Sakana AI. Written by Stefania Druga, Luke Darlow, and Llion Jones. The biggest differentiator? Understanding over implementation. Read it: pub.sakana.ai/Unofficial_G...

RePo moves us toward models that intelligently curate their own working memory rather than passively accepting input order. Read the full breakdown on our website: pub.sakana.ai/repo/ Paper: arxiv.org/abs/2512.14391

Introducing RePo: Language Models with Context Re-Positioning Standard LLMs force a rigid linear structure on context, treating physical proximity as relevance. Cognitive Load Theory suggests this is inefficient—models waste capacity managing noise instead of reasoning. arxiv.org/abs/2512.14391

2026 is just getting started 🚀✨ We are hiring. Join our team in Tokyo! sakana.ai/careers

AI導入は「雇用不安小さい正社員制度が強みに」 日経ビジネスにて、Sakana AI CEO @hardmaru.bsky.social のインタビューが公開されました。企業へのAI実装が本格化する2026年における現状と課題、そして日本企業の組織文化がAI導入にとってポジティブに働く可能性について語りました。 business.nikkei.com/atcl/gen/19/... 【記事のハイライト】🧵

Introducing DroPE: Extending Context by Dropping Positional Embeddings We found embeddings like RoPE aid training but bottleneck long-sequence generalization. Our solution’s simple: treat them as a temporary training scaffold, not a permanent necessity. arxiv.org/abs/2512.12167 pub.sakana.ai/DroPE

One of my favorite findings: Positional embeddings are just training wheels. They help convergence but hurt long-context generalization. We found that if you simply delete them after pretraining and recalibrate for <1% of the original budget, you unlock massive context windows. Smarter, not harder.

We are taking our technology far beyond competitive programming to unlock a new era of AI-driven discovery. We are hiring. Join our team in Tokyo. sakana.ai/careers/#sof...

When agents compete for limited resources, intelligence reorganizes around survival, not elegance.

Survival of the fittest code! Our paper explores LLMs driving an evolutionary arms race in Core War, where assembly programs fight each other. We task LLMs with evolving "Warriors" in a virtual machine, producing chaotic, self-modifying code dynamics. Blog: sakana.ai/drq Paper: pub.sakana.ai/drq/

Introducing Digital Red Queen (DRQ): Adversarial Program Evolution in Core War with LLMs. In this work, we explore how LLMs can drive open-ended adversarial evolution of programs within the Core War environment. Blog sakana.ai/drq Website pub.sakana.ai/drq/ ArXiv arxiv.org/abs/2601.03335 Thread:

So proud of Team Sakana AI for pulling this off! We managed to get an agent to rank #1 in a difficult heuristic optimization contest. We leaned heavily into test-time inference using a mix of frontier models. The agent spent $1,300 to autonomously discover an algorithm that beat the human baseline.

Our AI agent has achieved 1st place in a competitive optimization programming contest against over 800 human participants. Blog: sakana.ai/ahc058 Thread:

Happy New Year! ⛩️

Sakana AI’s office looks like this.

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...

『日経ビジネス』のインタビュー記事が公開されました。 日本の組織構造は長年の知恵の結晶であり、無理にフラット化すべきではありません。特性の異なるAIを組み合わせ、既存の蓄積を代替するのではなく、人に寄り添う「コンパニオン」であるべきです。組織の強みを活かすAIの在り方を語りました。

“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.

“In my view, AI is ultimately going to be a normal technology. In 20 years, our kids will just be using a chat bot like it’s a fax machine. It won’t be magical anymore. This will just be integrated and adapted into our collective system.” Gave my 2c at #BloombergNewEconomy Forum

Just realized I knew all about hedging ‘AI risks’ >15 years ago 😅

Excited to announce our book “Neuroevolution: Harnessing Creativity in AI Agent Design” by Sebastian Risi, Yujin Tang, Risto Miikkulainen, and myself. We explore decades of work on evolving intelligent agents and shows how neuroevolution can drive creativity in deep learning, RL, LLMs and AI Agents!

Excited to announce Sakana AI’s Series B! 🐟 sakana.ai/series-b From day one, Sakana AI has done things differently. Our research has always focused on developing efficient AI technology sustainably, driven by the belief that resource constraints—not limitless compute—are key to true innovation.

Great to see Tarin Clanuwat featured for her amazing work. She has a deep love for Japanese classical literature and is using AI to build bridges to that past for everyone. www.tokyoupdates.metro.tokyo.lg.jp/post-1670/ We’re lucky to have her driving this at Sakana AI.

To me, the field of A.I. is a branch of Philosophy, not Science. I would even call it “Applied Philosophy”.

The US government should subsidize Open AI rather than OpenAI

Excited to release our new work: Petri Dish Neural Cellular Automata! pub.sakana.ai/pdnca We investigate how multi-agent NCAs can develop into artificial life 🦠 exhibiting complex, emergent behaviors like cyclic dynamics, territorial defense, and spontaneous cooperation.

Proud to release ShinkaEvolve, our open-source framework that evolves programs for scientific discovery with very good sample-efficiency! 🐙🧠 Paper: arxiv.org/abs/2509.19349 Blog: sakana.ai/shinka-evolve/ GitHub Project: github.com/SakanaAI/Shi...

Due to physical resource constraints, we currently estimate that around 300–400 of the candidate papers recommended for acceptance by the ACs will need to be rejected. We seek the support of our 41 SACs in addressing this distributed optimization problem in a fair and professional manner.
