pxpipe hides text in PNGs to cut AI coding costs

Turning a wall of text into a PNG so a coding model reads pixels instead of tokens is the kind of scrappy trick that only shows up when someone is actually annoyed by their API bill. It works because image tokens are still priced differently than text tokens in most model APIs, a pricing quirk few people think to exploit. The real story is what it says about the coding agent economy right now, where token costs are painful enough that developers will hack the input format itself rather than wait for vendors to fix pricing.
