Model
GPT-5.5 API pricing
Compare the published GPT-5.5 API list rate with corouter's outlet rate, review context and modalities, and estimate a monthly token bill.
Where this model fits
- Deep multi-step reasoning over large mixed document sets
- Vision-assisted extraction from screenshots and scanned PDFs
- High-stakes code review and refactoring assistance
Estimates only. Actual billing depends on your real token counts, cache hit rate, and the prices in effect at request time.
