Check out pxpipe, a new open-source tool designed to slash Anthropic API costs. Since Anthropic bills based on pixel count rather than word count for image inputs, this repo converts Claude prompts into optimized images before sending them. By leveraging this technique, the creator managed to reduce their total usage by at least 10x. It is an ingenious way to bypass the standard token-heavy billing and make high-volume prompt engineering significantly more affordable. I feel like this will become more useful when they move the model out of subscription. Be warned this is a lossy technique according to their own documentation. But only way to find out if it truly works for your use case is to try it out :)
