🤖 🧠 🧪 New paper! I'm presenting it TOMORROW at #ALIFE2026! What if a chip could heal itself the way a brain does: not with a spare part, but by rewiring around the wound? Meet Self-Organising Digital Circuits. 👉 self-organising-circuits.github.io/ (go murder some logic gates, I'll explain) 🧵⬇️

Self-Organising Digital Circuits
Extending the Neural Cellular Automata paradigm from pattern formation on grids to functional logic generation and self-repair on arbitrary graphs.

Conversable Complexity: Agentic LLM Collectives as Interpretable Substrates
Complexity and interpretability rarely coincide: systems rich enough for complex behaviours to emerge are usually too opaque to question, while transparent ones are too simple for anything complex to ...

I’m proud to be part of this work, led by my PhD student @smearle.bsky.social and supervised by @risi.bsky.social. The question we ask is whether modern VLMs can exhibit the same kind of open-ended search and invention as humans when placed in the same mechanism

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!

Ever wish you could coordinate thousands of units in games such as StarCraft through natural language alone? We are excited to present our HIVE approach, a framework and benchmark for LLM-driven multi-agent control.

Hi, I'm Joachim, I work as a postdoc on the Grow-AI project lead by @risi.bsky.social at ITU of CPH. My PhD is titled "Bio-Inspired Approaches to Adaptive Artificial Agents" and since then, a lot of my time has revolved around Neural Developmental Programs: watermark.silverchair.com/isal_a_00755...

This may sound odd, but game-based benchmarks are some of the most useful for AI, since we have human scores and they require reasoning, planning & vision The hardest of all is Nethack. No AI is close, and I suspect that an AI that can fairly win/ascend would need to be AGI-ish. Paper: balrogai.com
