We are pleased to share our latest research, now published in Nature Communications: “Smart Cellular Bricks: Physical Modules That Recognize Their Own Shape and Repair Themselves.” Blog: sakana.ai/smart-cellul... Paper: www.nature.com/articles/s41... Thread 🧵

Smart cellular bricks for decentralized shape classification and damage recovery | Nature Communications nature.com
AI Weekly's analysis →
  • Cubic bricks running identical neural cellular automata policies classified four 3D shapes with 98.97% accuracy in simulation and 100% on physical hardware.
  • Physical builds ranged from 26 bricks for a guitar to 197 for a round table, converging on a shape label in fewer than 60 update cycles.
  • The same decentralized framework detects structural damage with over 90% accuracy and guides regrowth by predicting one of six axis directions.

Introducing "Scaling In-Context Imitation Learning" (SAIL) to be presented at #IROS2026. This work is a collaboration between Sakana AI and the University of Tokyo. Blog: pub.sakana.ai/sail Paper: arxiv.org/abs/2603.08269 What does a robot need before it can tackle a new task?…

SAIL: Test-Time Scaling for In-Context Imitation Learning with VLM arxiv.org
AI Weekly's analysis →
  • SAIL reframes robot imitation as MCTS over full trajectories, guided by a VLM scorer, step-level feedback, and a retrieval archive of past successes.
  • Across six simulation manipulation tasks, average success rose from 25% at one rollout to 73% at 45 MCTS nodes, reaching 95% on HandOverBanana.
  • On a real-world BlockIntoBowl task with a LeRobot SO-101 arm, the method succeeded in five of six trials; the paper is accepted to IROS 2026.

The AI Picbreeder Experiment: Can AI agents be creative when nobody tells them what to create? Blog: pub.sakana.ai/picbreeder-vlm Paper: arxiv.org/abs/2605.23908 In our #GECCO2026 paper, we revisit Picbreeder, a website where people collaboratively evolved images without any p…

In Search of the Ingredients of Open-Endedness: Replicating Picbreeder with Large Vision-Language Models arxiv.org
AI Weekly's analysis →
  • Researchers Sam Earle, Kai Arulkumaran, Andrew Dai, Akarsh Kumar, Julian Togelius and Sebastian Risi replicate Picbreeder with frontier vision-language models as users.
  • The system's output shows 'clear qualitative differences' from the historical human baseline on phylogenetic complexity and visual and semantic salience and novelty.
  • The team studies three candidate ingredients: exploratory noise in selection, behavioral diversity between agents, and memory-based narrative momentum.

Introducing Fugu Max and Fugu Ultra v2: the next evolution of Sakana Fugu’s multi-agent orchestration system. Try: sakana.ai/fugu Blog: sakana.ai/fugu-max-rel... The frontier that actually matters is the Pareto frontier: capability on one axis, cost on the other.

Sakana Fugu — Multi-agent System as A Model sakana.ai
AI Weekly's analysis →
  • Fugu routes tasks through a dynamic multi-agent pipeline exposed as a single OpenAI-compatible API, removing orchestration setup from users.
  • The system draws on two ICLR 2026 papers: TRINITY assigns Thinker/Worker/Verifier roles; Conductor uses reinforcement learning to design coordination strategies.
  • Fugu Ultra scored 73.7 on SWE Bench Pro and 93.2 on LiveCodeBench; base Fugu reached 95.5 on GPQA-D, per Sakana's own benchmark reporting.

AI Weekly's analysis →
  • Fugu Max prices at $2 per million input tokens and $6 per million output tokens, which Sakana claims runs 40-60% below Sonnet 5, GPT 5.6 Terra, and Kimi K3.
  • The system routes each task across a swappable pool of open-weight and specialized models, with NVIDIA's Nemotron folded in via an August 2026 collaboration.
  • Fugu Ultra v2 scores 48.3 on Chartography against Opus 5's 27.3, and does so without Fable 5, Fable 5.1, or GPT-6-Astra in its agent pool.

Introducing PC-ALM: a local-learning alternative to backprop that trains 1000-layer neural nets using only local dynamics. Blog: pub.sakana.ai/pc-alm/

Augmented Lagrangian Predictive Coding: training 1000-layer networks without backpropagation pub.sakana.ai
AI Weekly's analysis →
  • PC-ALM adds a per-layer Lagrange multiplier to predictive coding so that only layer-local updates recover backpropagation-aligned credit signals.
  • Sakana reports 1000-layer residual MLPs on MNIST land within roughly two percentage points of backprop using a T=2L inference budget.
  • On Fashion-MNIST at width 32 and depth 32, PC-ALM hits 77.75% accuracy versus 78.66% for backprop and 68.13% for vanilla predictive coding.

Smart Cellular Bricks: Towards Collective Intelligence for the Physical World sakana.ai
AI Weekly's analysis →
  • IT University of Copenhagen, Sakana AI, and Autodesk built cubic bricks that classify their own assembled 3D shape using only neighbor-to-neighbor communication.
  • In simulation the system hit 98.97% accuracy across 500+ bricks; four physical objects (26 to 197 bricks) all reached correct consensus in under 60 cycles.
  • The same Neural Cellular Automata substrate detects local damage at 94.8% average accuracy, with some shapes degrading only minimally at 15% brick failure.
