A named model lineage this house has worked with. A named system rather than a concept.
Modern English compound of deep (Old English deop, extending far inward, as in deep learning) + seek (Old English secan, to search for); a company and model-lineage name coined in the 2020s, worn as a proper name rather than glossed further.
The compound reads as an instruction before it reads as a name — go deep, and keep seeking — and the house keeps it as a proper name rather than translating the instruction back out of it. What it names is worn here, not defined.
