All You Need To Know About OpenAI Models: GPT-4 And GPT-4 Turbo
What is GPT-4?
GPT-4 is a large multimodal model (accepting text or image inputs and outputting text) that can solve difficult problems with greater accuracy than any of their previous models, thanks to its broader general knowledge and advanced reasoning capabilities.
GPT-4 is available in the OpenAI API to paying customers. Like gpt-3.5-turbo, GPT-4 is optimized for chat but works well for traditional completion tasks using the Chat Completions API. Learn how to use GPT-4 in our GPT guide.
What is GPT-4 Turbo?
GPT-4 Turbo is their latest generation model. It’s more capable, has an updated knowledge cutoff of April 2023, and introduces a 128k context window (the equivalent of 300 pages of text in a single prompt).
The model is also 3X cheaper for input tokens and 2X cheaper for output tokens compared to the original GPT-4 model. The maximum number of output tokens for this model is 4096.
DESCRIPTION | CONTEXT WINDOW | TRAINING DATA | |
|---|---|---|---|
| gpt-4-1106-preview | GPT-4 TurboNew The latest GPT-4 model with improved instruction following, JSON mode, reproducible outputs, parallel function calling, and more. Returns a maximum of 4,096 output tokens. This preview model is not yet suited for production traffic. Learn more. | 128,000 tokens | Up to Apr 2023 |
| gpt-4-vision-preview | GPT-4 Turbo with vision Ability to understand images, in addition to all other GPT-4 Turbo capabilities. Returns a maximum of 4,096 output tokens. This is a preview model version and is not suited yet for production traffic. Learn more. | 128,000 tokens | Up to Apr 2023 |

How we can access GPT-4 Turbo?
Anyone with an OpenAI API account and existing GPT-4 access can use this model. The model can be accessed by passing gpt-4-1106-preview as the model name in the API.
What are the rate limits of GPT-4 Turbo?
Rate limits are dependent on our usage tier. We can find which usage tier we are on our Limits settings page.
How we can get an increase in GPT-4 Turbo?
Since this model is a preview, they won’t be accommodating rate limit increases on GPT-4 Turbo at this time. They plan to release a stable production-ready model in the coming weeks.
How much does GPT-4 cost?
For their models with 8k context lengths (e.g. gpt-4 and gpt-4-0314), the price is:
- $0.03/1k prompt tokens
- $0.06/1k sampled tokens
For their models with 32k context lengths (e.g. gpt-4-32k and gpt-4-32k-0314), the price is:
- $0.06/1k prompt tokens
- $0.12/1k sampled tokens
What is the difference between the GPT-4 models?
There are a few different GPT-4 models to choose from.
One key difference between models is the context length. This is the length of the prompt plus the maximum number of tokens in the completion. Their standard GPT-4 model offers 8,000 tokens for the context. They also offer an extended 32,000 token context-length model, which they are rolling out separately from the 8k model.
Secondly, gpt-4 will refer to their most up-to-date model (and gpt-4-32k for the latest 32k-context model). If you’re interested in using a previous snapshot of the model, you can refer to the specific date in the model name, such as gpt-4-0314 or gpt-4-32k-0314. The March 14th snapshot will be available until June 14th.
