16. Developers optimize Fable 5 input with image-based text
Developers have found a way to reduce costs for feeding Fable 5 large context by rendering text into images, which can be read by the model using OCR-like vision skills, although this method may not be suitable for byte-exact facts. This approach allows for cheaper input, as a single image can hold a large amount of text at a fixed token cost.
