Module cost 

Token cost estimation for AI vision providers.

Both OpenAI and Anthropic charge tokens for image inputs based on image dimensions. This module implements the public token-counting formulas so SHIFT can report estimated savings.

Structs

ImageMetrics

Per-image before/after metrics for the report.

TokenEstimate

Estimated token counts for a single image across providers.

TokenSavings

Aggregate token savings across all images.

Functions

anthropic_tokens

Anthropic vision token count for standard-resolution models.

estimate_tokens

Estimate tokens for an image at given dimensions.

openai_tokens

OpenAI vision token count for detail: high.

openai_tokens_low

Fixed token count for OpenAI detail: low.
