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.

Excited to share CoffeeBench!!☕️☕️☕️ We evaluate LLM agents in a 90-day B2B coffee supply-chain economy spanning farmers, roasters, and retailers, where autonomous firms negotiate, manage inventory, set prices, handle invoices, and manage cash flow. arxiv.org/abs/2606.16613 gi…

CoffeeBench: Benchmarking Long-Horizon LLM Agents in Heterogeneous Multi-Agent Economies arxiv.org
AI Weekly's analysis →
  • CoffeeBench runs LLMs as autonomous business operators across a 90-day, six-firm economic simulation.
  • Claude Haiku 4.5 exhibits 'idle-drift': producing coherent plans but persistently choosing inaction.
  • Higher-performing models communicate more actively with counterpart firms, correlating with better outcomes.

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.

Today, we are taking a major step toward that future with the launch of Sakana Fugu. Fugu dynamically orchestrates the world’s best models to tackle complex tasks. We’re proving that a well-orchestrated pool of swappable agents can match restricted frontier models like Fable/M…

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.

Dive into our new AI Picbreeder Experiment here: pub.sakana.ai/picbreeder-v...

The AI Picbreeder Experiment: In Search of Automatic Open-Endedness pub.sakana.ai
AI Weekly's analysis →
  • Researchers from NYU, MIT and Sakana AI replaced Picbreeder's human selectors with frontier VLMs and reported clear qualitative gaps versus the historical human baseline.
  • Gemini-2.5-pro topped the models tested, but archives showed 'mode collapse' without exploratory noise and 'auto-sycophantic' loops when given more history.
  • Scaling to 1,000 agents widened coverage yet 10 to 20 percent of the archive turned into uninterpretable adversarial psychedelic patterns.

Recent commentary

Language models and coding agents are great, but there is more to life, and more to AI, than just LLM agents.
