Home-labbing 7 GPUs for OCR lost to Google API on cost, researcher finds
RexDouglass · x · 2026-09-19
Researcher Rex Douglass shares his home-lab experiment: processing tens of millions of paper documents with 7 home GPUs, the cooling and electricity costs were never worth it versus just paying for the Google API. His interlocutor adds that no open-weight setup proved feasible at 20M-case scale. Conclusion: at scale, self-hosting almost always loses to cloud APIs.
