Fruit fly brain sim wired to a 1B LLM: 139,255 neurons now chat with you
TinfoilTricorn · x · 2026-09-12
A developer connected a full fruit fly brain connectome simulation to a 1B-parameter LLM: 139,255 neurons and 2.7 million synaptic connections.
Your message is converted into a sensory stimulus, the brain simulation runs, and the model reads the resulting neural activity to generate a reply — effectively letting you talk to a fruit fly's brain. A quirky but real crossover between connectome data and LLM generation pipelines, building on the recently released fly connectome.
