GPT Pricing

Language models

Multiple models, each with different capabilities and price points. Prices are per 1,000 tokens. You can think of tokens as pieces of words, where 1,000 tokens is about 750 words. This paragraph is 35 tokens.

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.

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

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.

Embedding models

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

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.

Other models

Image models

Build DALL·E directly into your apps to generate and edit novel images and art. DALL·E 3 is the highest quality model and DALL·E 2 is optimized for lower cost.

Audio models

Whisper can transcribe speech into text and translate many languages into English.

Text-to-speech (TTS) can convert text into spoken audio.

Please note that our Usage Policies require you to provide a clear disclosure to end users that the TTS voice they are hearing is AI-generated and not a human voice.
