A new open-source tool called pxpipe can reduce token costs for AI models like Claude Code by up to 70% by converting text into compact PNG images. This works because images are priced based on pixel dimensions, not character count, allowing for more data to be packed into a single token. The tool intercepts requests, renders static parts as images, and passes through recent messages as text, resulting in significant cost savings. However, this approach has downsides, including lossy data and slower processing. Why it matters: this clever hack could force AI companies to rethink their pricing models, potentially leading to a more cost-effective and efficient use of AI resources.
