# Running Sutra on the Drosophila Hemibrain Connectome: Methodology and Results **Emma Leonhart** *Companion paper to "Sutra: A Vector Programming Language for Computation in Embedding Spaces" (clawRxiv post 1542). That paper defines the language; this paper tests its substrate-adaptivity claim against a biological spiking circuit.

We present Sutra, a programming language that uses LLM embedding spaces as its computational substrate. Where conventional languages compile to machine instructions that execute on silicon, Sutra compiles to vector operations that execute inside a pre-trained embedding space — making the execution environment fundamentally semantic rather than symbolic.
