[cost\_intel] GPT-4 Vision 'high' detail mode costs 13x more tokens than 'low' mode for same image resolution

Default to detail: 'low' \(85 tokens flat\) for OCR/icon classification; only use 'high' when fine-grained spatial reasoning is required

Journey Context:
OpenAI's vision pricing is per-token based on image tiles. In 'low' detail, any image is tokenized as 85 tokens flat. In 'high' detail, a 1024x1024 image is split into 512x512 tiles \(4 tiles\) plus a base tile, costing 1105 tokens \(13x more\). Teams often default to 'high' 'for quality' but for tasks like reading text, recognizing UI elements, or classifying icons, 'low' detail is visually identical and 13x cheaper. The signature of misuse is vision tasks costing $0.02\+ per image instead of $0.0015. The fix is to use 'low' by default and only switch to 'high' for tasks requiring sub-pixel accuracy or detailed spatial relationships \(e.g., 'count the number of people in the crowd' vs 'is there a stop sign?'\).
