Current GPT API model prices

Rates are first-party USD list prices per one million tokens. Current models are ordered by catalog relevance, not by price alone. Marketplace-only prices are excluded so they cannot be mistaken for the model creator's API rate.

Cost guidance

How to compare GPT API costs

01

Separate input and output tokens before comparing models; generation-heavy workloads can be dominated by output pricing.

02

Choose a model for the capability you need, then compare the cost of the same token workload instead of headline rates alone.

03

Confirm cached-input, batch, fine-tuning, and tool charges on OpenAI's official pricing page before budgeting production traffic.

Questions

GPT API pricing FAQ

How is OpenAI API usage priced?

Text-model usage is generally priced separately for input and output tokens. Some models or service modes may add cached-input, batch, tool, or fine-tuning charges.

Does this page replace OpenAI's official pricing documentation?

No. LLM Cost provides a comparison and workload estimator. Confirm final purchasing decisions against OpenAI's official pricing page.
