What this page is
This page lists every multimodal model (vision capable) with priced API access, ranked cheapest first. Note that per-image billing can diverge from per-token billing: a single high-res image may cost hundreds of tokens depending on the provider. Use the input price below as a baseline, then check the model detail page for image-specific pricing notes. Ideal for OCR, document processing, chart reading, and visual QA.

Multimodal models only, cheapest first.

Why the gap

Premium vision models pay for higher resolution encoders, better chart and table reading, and longer context for multi-page documents. For batch OCR, the cheap end is often good enough.

Most providers bill images as a fixed token count based on resolution. OpenAI bills ~255 tokens per low-res image, 765+ for high-res. Anthropic bills by image dimensions. Google bills flat per image. Always check the provider docs before budgeting.
