Hidden Costs Breakdown

Image/Vision Token Overhead

medium overage

Image inputs are converted to tokens using the formula (width px × height px) / 750, meaning a 1,000×1,000 pixel image consumes approximately 1,334 tokens. At 1M+ images, vision workloads can cost $4,000+ in input tokens alone before output costs.

The formula for token calculation is: (width px * height px) / 750. Here are some examples: 200x200 px Image: 54 tokens, costing roughly $0.0016 per image. 1000x1000 px Image: 1334 tokens, costing about $0.004 per image. 1092x1092 px Image: 1590 tokens, costing near $0.0048 per image. The costs for Claude Vision are based on a rate of $3 per million input tokens.

At high production volumes, Claude API costs can reach tens of thousands of dollars per two-week period. One developer reported that 4.5 billion tokens processed over 14 days would have cost $15,000 with Claude at $3/$15 per million tokens in/out, compared to $280 on their own self-hosted infrastructure.

In the last 14 days that model processed about 4.5B tokens for $280, or about: $0.0007 per million tokens in, and $0.01 per million tokens out. With Claude that would have been $15,000 @ $3/$15.
