What Is GPT-5.6 Luna?
GPT-5.6 Luna is an AI model from OpenAI that can be accessed through an API. Developers can use the model to build AI-powered applications, assistants, automation workflows, content tools, and other software products.
API costs depend on the number of input and output tokens processed by the model. The calculator below lets you estimate those costs using your expected request volume and average token usage.
How Much Does GPT-5.6 Luna Cost?
The cost of using GPT-5.6 Luna depends primarily on the number of input tokens, output tokens, and API requests processed by your application.
To estimate the cost of a request, the input token usage is multiplied by the input price and the output token usage is multiplied by the output price.
Cost = (Input Tokens ÷ 1,000,000 × Input Price)
+ (Output Tokens ÷ 1,000,000 × Output Price)

What Affects GPT-5.6 Luna API Cost?
API Request Volume
More API requests generally mean higher total spending. Estimating daily request volume is one of the easiest ways to forecast your monthly API bill.
Input Tokens
Prompts, instructions, conversation history, documents, and other context contribute to input token usage. Larger inputs increase the cost of each request.
Output Tokens
Generated responses contribute to output token usage. Longer responses can significantly increase total API spending depending on the model's output price.
Model Pricing
Different AI models can have different input and output prices. Comparing models with the same token usage can help you evaluate potential cost differences.
Estimate Your GPT-5.6 Luna API Budget
