In the model picker, Auto automatically switches between Instant and Thinking, and you can also choose additional options directly from the top of the model picker.

• Instant — instant answers

• Thinking — deeper reasoning

Please note that the context window is 128K for Instant and Thinking, and 272K for Pro.

Note on Unlimited Access

The ChatGPT Business plan offers virtually unlimited messages for the 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.
