If you’re considering using OpenAI’s cutting-edge language models to enhance your applications or services, one of the first things you’ll want to know is how much it costs.

In this article, we’ll explore OpenAI API pricing in detail, including the different pricing plans available, how much you can expect to pay, and what factors might affect the final cost.


OpenAI is a leading AI research laboratory that has developed some of the most advanced language models in the world, such as GPT-3, DALL-E, and CLIP.

These models are trained on massive amounts of data and can perform a wide range of natural language processing (NLP) tasks, such as text generation, language translation, sentiment analysis, and more.

To make these models accessible to developers and businesses, OpenAI offers an API (application programming interface) that allows users to integrate them into their own applications or services.

Using the API comes at a cost, and understanding the pricing structure is crucial to making an informed decision.

Understanding OpenAI API Pricing

OpenAI API pricing is based on a combination of two factors: usage-based pricing and pre-paid plans.

This means that you can either pay for what you use on a per-request basis or purchase a pre-paid plan that gives you a certain amount of usage for a fixed price.

Different Pricing Plans

Usage-based pricing

Usage-based pricing is the most flexible option, as you only pay for what you use. The cost per request depends on the complexity of the language model and the volume of requests.

For example, the cost of generating a short text response with the GPT-3 model is around $0.06 per request, while the cost of generating a long-form article can be as high as $1.50 per request.

Pre-paid plans

Pre-paid plans offer a discount for purchasing a certain amount of usage in advance. OpenAI offers three pre-paid plans:

  • Explorer: $100 for 5,000 API requests
  • Voyager: $400 for 25,000 API requests
  • Adventurer: $1,000 for 100,000 API requests

These plans can be a good option if you have a predictable amount of usage and want to save money compared to usage-based pricing.

Factors Affecting the Final Cost

The final cost of using OpenAI’s API depends on several factors, including:

Language Model Complexity

The more complex the language model, the higher the cost per request.

For example, using the GPT-3 model costs more than using the GPT-2 model, as the former is more powerful and capable of generating more nuanced responses.

Request Volume

The more requests you make, the higher the total cost. OpenAI offers volume discounts for usage-based pricing, so if you expect to make a large number of requests, it may be more cost-effective to choose this option.

Quality of Service

OpenAI offers different levels of service quality, with higher levels providing faster response times and more reliable service.

Choosing a higher quality of service will increase the cost per request.

Comparison with Competitors

Finally, it’s important to compare OpenAI’s pricing with that of other language model APIs on the market.

While OpenAI’s models are some of the most advanced, there are other APIs that offer similar functionality at a lower cost.

However, it’s important to consider the quality of the models and the level of support provided by the API provider when making this comparison.


OpenAI’s language models are some of the most advanced and powerful in the world, and using them can bring significant benefits to your applications or services.

However, it’s important to consider the cost of using OpenAI’s API, as this can vary depending on several factors, such as model complexity, request volume, and service quality.

By understanding the different pricing plans and factors that affect the final cost, you can make an informed decision about whether OpenAI’s API is the right choice for your needs.


Can I use OpenAI’s API for free?

No, OpenAI’s API is not available for free. However, there is a free trial available that allows you to test the API with a limited number of requests.

How does OpenAI’s API pricing compare to other language model APIs on the market?

OpenAI’s API pricing is generally higher than that of other language model APIs, but the quality of the models is also higher.

Can I switch between usage-based pricing and pre-paid plans?

Yes, you can switch between these two pricing options at any time, depending on your usage needs.

Is there a limit to the number of requests I can make with OpenAI’s API?

No, there is no limit to the number of requests you can make with OpenAI’s API, as long as you are within the usage limits of your pricing plan.

Can I get a refund if I’m not satisfied with OpenAI’s API?

OpenAI does not offer refunds for usage-based pricing, but you can cancel your pre-paid plan and receive a prorated refund for the unused portion.
