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

What changed
The Fly Language Model combines a full fruit-fly brain wiring map with a frozen 1.2-billion-unit language model, training only a small added component. Although it improved on the original system, a similarly sized version without the fly wiring performed slightly better in every test run.
What this means for you
This is mainly a research result rather than a ready-to-use product: the evidence suggests that adding biological wiring does not automatically improve a language model. The code is MIT-licensed and can be run locally, but the reported benefit is small and the graph-based design performed worse than its simpler control.
