GPT‑6 Pro, powered by GPT‑6 Astra, is rolling out in ChatGPT for Pro $100, Pro $200, Business and Enterprise plans. Enterprise access also depends on your workspace’s model-access permissions. Plus plans include GPT‑6 Astra in ChatGPT Work and Codex as it rolls out. Rollout is gradual, and availability can differ between Chat, Work and Codex.
Note: Astra requires Codex CLI version 0.153.0 or newer. Additionally, please update to the latest available ChatGPT Desktop app.
Enterprise and Edu members can use the models currently enabled for their workspace. Model availability and limits change over time, so the model picker and workspace settings are the source of truth for current access.

If you are on ChatGPT flexible pricing, please refer to this page for the latest rates on our models, features, and products.
Model access in Enterprise and Edu is controlled through workspace settings and RBAC. Admins and owners can review access in workspace settings. The options members see can vary by rollout and workspace configuration.
Model Picker
The model picker uses simplified controls to help members choose the balance of speed and reasoning effort that works best for their task. Note that the model options shown in the picker depend on workspace settings and rollout status.
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.
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, context windows, usage limits, or credit rates. For workspaces using flexible pricing, see the ChatGPT Rate Card.
Managing automatic routing for reasoning
Enterprise and Edu admins may have automatic-routing controls under Workspace settings > Models. Available controls and their names can vary by workspace and rollout.
To update this setting:
Go to Workspace settings.
Under Models, review the available automatic-routing controls.
Automatic routing applies only when the selected chat experience routes a request to reasoning. Members can still choose any reasoning options enabled for them.
Note on Unlimited Access
The ChatGPT Enterprise 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.
New model access controls in Workspace settings
In eligible ChatGPT Enterprise and Edu workspaces, GPT-6 Astra is off by default at launch. It is rolling out gradually, so access may not be available to all eligible workspaces yet. Once available, workspace owners can enable it for the workspace or for specific roles through the model access controls in workspace settings.
Existing Early Model Access settings do not carry over to Astra. Having Early Model Access turned on does not automatically give members access to Astra.
If a member cannot see Astra in the model picker, first check rollout availability, then their model-access permissions and all assigned roles. A role that allows access can keep it enabled even if another role turns it off. You can only choose a workspace default from models available to your workspace.
The two-week admin preview process is not available for Astra at launch. Access will not automatically turn on two weeks after launch.
Choosing a starting or default model does not grant access to a model the member cannot use. For help managing roles, see Role Based Access Controls for ChatGPT Enterprise.
