Using "underdrawings" for accurate text and numbers

2 days ago

The author discovered a technique to generate reliable text and numbers in AI-generated images, surpassing current state-of-the-art models like Gemini 3.0 Pro and ChatGPT-Images-2.
The technique involves a two-step process: creating a deterministic 'underdrawing' (e.g., using SVG) with correct text and numbers, then using generative AI to apply a visual style without altering the text.
An example prompt for a game board with 50 stepping stones in a spiral was used to demonstrate the failure of Gemini and ChatGPT in accurately rendering numbers, while the author's method succeeded.
The author suggests tools like Claude can automate the steps, making the technique accessible, but notes it's not perfect every time (e.g., a 'reality check' with an error like 71).
