Overview

ChatGPT Business includes ChatGPT, ChatGPT Work, and Codex. The plan offers two types of seats: Standard and Premium, which include usage for ChatGPT features such as thinking models, coding, and agentic features. Premium seats offer more included usage for ChatGPT Work and Codex; individual ChatGPT model allowances are separate. Model and feature availability also depend on your workspace settings.

For additional usage beyond included allowances, see:Flexible pricing for the Enterprise, Edu, and Business plans, and the ChatGPT Rate Card.

Model picker

Use the model picker to select the reasoning level for your ChatGPT conversation. The available options can vary by workspace and rollout:

• Instant: Responds quickly using GPT-5.6 Sol.

• Medium: Uses GPT-5.6 Sol with standard reasoning.

• High: Uses GPT-5.6 Sol with extended reasoning.

• Extra High: Uses GPT-5.6 Sol with its highest selectable reasoning effort.

• Pro: Uses GPT-5.6 Sol Pro. Additional reasoning controls may be available for this option.

Note that Pro is a model option, not another name for a Premium seat.

ChatGPT can also add reasoning automatically while Instant is selected. To manage this behavior, go to Settings > General and adjust Higher intelligence. Automatic reasoning may use your reasoning allowance even while Instant remains selected.

ChatGPT Work and Codex have their own model controls and support GPT-5.6 Sol, Terra, and Luna where available. Terra and Luna are not selectable options in ordinary ChatGPT conversations.

For model availability, see:GPT-5.6 in ChatGPT. For the differences between experiences, see:ChatGPT Work and Codex.

Note on unlimited access

Virtually unlimited access applies to Instant chat and remains subject to safeguards against misuse. It does not make reasoning, Pro, ChatGPT Work, Codex, or other tools unlimited. Automatic reasoning may use your reasoning allowance even while Instant remains selected. 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

Your included usage depends on your seat type and the experience you use. Premium seats provide a higher included allowance for ChatGPT Work and Codex. This does not mean every ChatGPT model or feature has a higher limit. Included allowances are different from workspace credits purchased for additional usage.

For ChatGPT Work and Codex, usage depends on the model, task size, reasoning effort, and amount of work performed. A longer task can use more of your allowance than a short task, so a fixed number of messages is not a reliable measure of remaining usage.

If you reach an included limit, eligible usage can continue with purchased workspace credits when credits are available and your workspace's spending controls allow it. Otherwise, wait for the applicable allowance to reset or use another available option. Reaching a limit for one experience does not mean every ChatGPT feature is unavailable.

When a change from Premium to Standard takes effect, the Standard limits apply. A scheduled downgrade does not reduce access before its effective date.

For current credit charges, see:ChatGPT rate card, for additional paid usage beyond the limits described below.

Local-message estimates by seat type

The estimates below show allowed local messages per 5-hour window. Actual usage varies by model and task; cloud chats can use more of an allowance than local messages. Premium seats have 5x the included usage of Standard seats, with the benefit of no 5-hour limit so users can maximize uninterrupted session time
