[cost\_intel] GPT-4o vision high\_res mode silent 10x cost multiplier for large images

Use low\_res \(85 tokens flat\) for text/OCR; use high\_res only for micro-detail. Calculate tiles: ceil\(width/512\)\*ceil\(height/512\)\*170 \+ 85 tokens

Journey Context:
High-res vision costs 170 tokens per 512x512 tile. A 2048x4096 image = 32 tiles = 5440 tokens \(~$0.16\) vs low-res 85 tokens \(~$0.0025\). For standard document OCR, low-res captures text identically; high-res only benefits medical imaging or circuit boards. Defaulting to high\_res on standard documents burns 64x tokens for zero OCR improvement. Degradation signature: high\_res shows no quality improvement on clean text but costs 10x more.
