Eric Lu created Ghost Font, a moving-dot typeface that humans can read, but some AI vision models struggle to decode. The trick is motion. Each letter only becomes clear when the dots move, while a single frame usually looks like random noise. According to the project, models like GPT Sol 5.6 Ultra and Claude Fable often missed the actual message. Some read the decoy text. Others gave completely wrong answers. Lu says Ghost Font is still a prototype, but it exposes an interesting weakness in AI vision systems: they can analyze frames, but still struggle to understand motion the way humans do.
