Open-source tool pxpipe hides text in PNGs to cut Claude Code and Fable 5 token costs up to 70%
A new open-source tool converts text prompts into PNG images to reduce token costs in Claude Code and Fable 5 by up to 70%.

- pxpipe converts text prompts into PNG images to reduce token costs in Claude Code and Fable 5 by 59-70%.
- Anthropic's pricing model charges by pixel size for images, not text content, enabling this cost-saving technique.
- The tool sacrifices accuracy and speed for cost efficiency, requiring users to decode images back to text.
- Developed by Steven Chong, pxpipe is an open-source solution targeting a common pain point for AI developers.
The open-source tool pxpipe, created by developer Steven Chong, offers a novel way to reduce token costs in Anthropic's Claude Code and Fable 5 by converting text prompts into PNG images. Since Anthropic charges for images based on pixel size rather than text content, this method can slash costs by 59 to 70%. The trade-off, however, includes reduced accuracy and slower processing speeds, as the system must first decode the image back into text before execution. This approach targets a growing pain point for developers using AI tools where token costs can quickly escalate, especially for long or complex prompts. While the savings are significant, users must weigh these against the potential downsides in performance and reliability.
