It doesn’t. Asking for confidence doesn’t prompt it to make multiple passes, and there’s no real concept of “passes” when you’re talking about non-reasoning models. The model takes in text and image tokens and spits out the text tokens that logically follow them. You can try asking it to think step by step, or you can use a reasoning model that essentially bakes that behavior into the training data, but I haven’t found that to be very useful for OCR tasks. If the encoded version of your image doesn’t resolve to text in the model’s latent space, it never will, no matter how much the model “reasons” (spits out intermediate text tokens) before giving a final answer.
