The ChatGPT Business subscription is a self-serve subscription plan designed for organizations and businesses wishing to adopt ChatGPT for use among their teams. ChatGPT Business is available for 2 or more users. If you're looking for a larger option, please consider ChatGPT Enterprise.

If you are on ChatGPT flexible pricing, please refer to this page for latest rates on our models, features and products.

Model Picker

The model picker uses simplified controls to help you choose the balance of speed and reasoning effort that works best for your task.

• Instant — Fast responses for everyday work. The underlying model can change as newer models roll out.

• Medium — Standard reasoning for tasks that benefit from more deliberate analysis.

• High — Extended reasoning for more complex, multi-step work.

• Extra High — The highest available reasoning effort for especially demanding tasks.

• Pro Standard — A Pro-tier option with standard reasoning effort, when available.

• Pro Extended — A Pro-tier option with extended reasoning effort, when available.

The options shown in the picker depend on your workspace and rollout status.

Automatic model routing, when available, can choose more reasoning for a request. Use the model picker's Configure controls to manage the routing settings available to you.

On iOS and Android, the picker appears at the top of the conversation. On web, it appears in the message composer.

The picker labels do not change the underlying models or usage limits.

The context window is 128K for GPT-5.6 Luna and GPT-5.6 Terra, and 272K for GPT-5.6 Sol.

Note on Unlimited Access

The ChatGPT Business plan offers virtually unlimited messages for eligible base models. However, usage must adhere to our Services Agreement, which prohibits, among other things:

• Abusive usage, such as automatically or programmatically extracting data.

• Sharing your account credentials or making your account available to anyone else.

• Reselling access or using ChatGPT to power third-party services.

We have guardrails in place to help prevent misuse and are always working to improve our systems. This may occasionally involve a temporary restriction on your usage. We will inform you when this happens, and if you think this might be a mistake, please don’t hesitate to reach out to our support team. If policy-violating behavior is not found, your access will be restored.

Models and limits

Please note that GPT-5.4 and GPT-5.2 have separate usage limit counters.
