Fly.exe is a neural simulator that runs a complete male fruit fly brain connectome (165,122 neurons and 25.5 million synaptic connections) in a physics-based virtual environment on a single GPU. Twelve simulated flies with embodied neural circuits navigate a virtual arena with food and obstacles, demonstrating goal-directed behavior driven purely by their connectome-based neural networks without explicit steering rules.
Show-Harness is an embodied interface that enables vision-language models to control robots through discrete semantic actions, allowing both closed-source frontier VLMs and fine-tuned open-source models to perform zero-shot and low-cost robot control. The system includes GUMI, a GUI manipulation interface for demonstration collection, and demonstrates robust generalization across tasks, embodiments, and environments without requiring additional model capacity or embodiment-specific pretraining.
