OpenAI Pricing Calculator is the latest, best, and most popular online tool that can be used on mobile, tablet, or computer devices to get a rough idea of how much it might cost to produce a certain number of words using the OpenAI GPT-3.5 and GPT-4 APIs.

Total Words: It refers to the number of words in a document or a piece of text. It is an important metric when it comes to calculating the cost of language processing services like those provided by OpenAI since the pricing is often based on the number of words or tokens.

Language Model: It has GPT-4, ChatGPT, Davinci, Curie, Babbage, and Ada language models. Each model has a different price for the tokens. This is why you need to choose a particular model from the list provided by OpenAI to know how much it costs for words.

Estimated Price: It is an approximation of the cost of a product or service, calculated based on a set of predetermined factors. In the context of the OpenAI Pricing Calculator, estimated price refers to the approximate cost of using the model to process a given amount of text or data.

GPT-4 Turbo

With 128k context, fresher knowledge and the broadest set of capabilities, GPT-4 Turbo is more powerful than GPT-4 and offered at a lower price.

GPT-3.5 Turbo

GPT-3.5 Turbo models are capable and cost-effective.

gpt-3.5-turbo-1106 is the flagship model of this family, supports a 16K context window and is optimized for dialog.

gpt-3.5-turbo-instruct is an Instruct model and only supports a 4K context window.

Model Input Output
gpt-3.5-turbo-1106 $0.0010 / 1K tokens $0.0020 / 1K tokens
gpt-3.5-turbo-instruct $0.0015 / 1K tokens $0.0020 / 1K tokens

Assistants API

Assistants API and tools (retrieval, code interpreter) make it easy for developers to build AI assistants within their own applications. Each assistant incurs its own retrieval file storage fee based on the files passed to that assistant. The retrieval tool chunks and indexes your files content in our vector database.

The tokens used for the Assistant API are billed at the chosen language model's per-token input / output rates and the assistant intelligently chooses which context from the thread to include when calling the model

Tool Input
Code interpreter $0.03 / session (free until 12/13/2023)
Retrieval $0.20 / GB / assistant / day (free until 01/12/2024)

Fine-tuning models

Create your own custom models by fine-tuning our base models with your training data. Once you fine-tune a model, you’ll be billed only for the tokens you use in requests to that model.

Model Training Input usage Output usage
gpt-3.5-turbo $0.0080 / 1K tokens $0.0030 / 1K tokens $0.0060 / 1K tokens
davinci-002 $0.0060 / 1K tokens $0.0120 / 1K tokens $0.0120 / 1K tokens
babbage-002 $0.0004 / 1K tokens $0.0016 / 1K tokens $0.0016 / 1K tokens

Embedding models

Build advanced search, clustering, topic modeling, and classification functionality with our embeddings offering.

Model Usage
ada v2 $0.0001 / 1K tokens

Base models

GPT base models are not optimized for instruction-following and are less capable, but they can be effective when fine-tuned for narrow tasks.
