A tool cuts your model bill 60% by turning text into pictures. The thread says it's arbitrage on a pricing bug, not compression (github.com)
pxpipe reflows text into ~1928px columns (~92,000 chars/page ≈ 4,761 vision tokens) and only converts where the math beats ~19 chars/token, claiming a 59–70% lower end-to-end bill. It's explicitly lossy: imaging a 12-char hex string recalled correctly only 13 of 15 times.
Commenters call it a token-accounting loophole, not efficiency. Gemini already OCRs PDFs and doesn't charge for the extracted text; a developer who tried the same trick last year got MORE completion tokens and a bigger bill.
