[cost\_intel] How does GPT-4o vision token pricing vary by image resolution and detail setting, creating 90x cost variance?

Always use 'low' detail mode for images >1024px where fine text doesn't matter; 'high' mode costs 85-7650 tokens \(avg 1000\+\) versus low's 85 tokens, a 90x difference for 2048px images.

Journey Context:
GPT-4o vision pricing is per token, but images are converted to tokens based on 512px tiles in high detail mode. A 2048x2048 image is divided into 16 tiles \(2048/512=4, 4x4=16\), each costing 170 tokens base plus metadata, totaling ~5100 tokens. Low detail uses a single 512px thumbnail = 85 tokens. Developers often default to 'auto' which selects high for large images, causing bill shock. For OCR of dense documents, high is necessary; for 'is this image a cat' or 'what color is the car,' low suffices. The 90x variance means one misconfigured high-res image costs the same as 90 low-res classifications.
