Fly Language Model (FLM) Wires the Full Fruit Fly Connectome Into a Frozen 1.2B LLM, and Its Own Controls Show the Wiring Does Not Help

The Fly Language Model (FLM) integrates the full fruit fly connectome into a frozen 1.2B parameter language model backbone but shows no performance improvement over a control without the fly wiring. The model uses a reservoir computing approach with fixed graph weights and trains only a small readout layer, demonstrating that the biological wiring does not enhance language modeling performance.
