In this guide, you’ll learn how to use Chat GPT Astra, which plans include access, how to get started with Codex, what the API costs, and what to do if you cannot find the model.
Learning how to use Chat GPT Astra can help you understand its features and choose the right workflow for your tasks.
How Does Astra Work Within Chat GPT?
First, let’s clarify the terminology. Chat GPT is the application, while GPT-6 Astra is a model designed for demanding tasks. You don’t need a separate account or a standalone Astra application.
Astra is designed to help with complex reasoning, software development, computer use, browsing, and professional workflows. Its capabilities extend beyond answering questions in a standard chat.
According to Open AI’s official introduction to GPT-6 Astra, the model is intended for complex work that may involve several steps and different tools.
Understanding these features makes it easier to learn how to use Chat GPT Astra for everyday and professional tasks.
Chat
Chat is designed for conversations, questions, explanations, and other everyday tasks. The models available in the interface depend on your plan and account access.
Work
Work is designed for longer, agent-style tasks. Depending on the available tools and permissions, you can use it for professional workflows and tasks that require multiple steps.
Codex
Codex focuses on software development. It can assist with coding, debugging, reviewing changes, and working across project files.
Do Free and Go Plans Include Astra?
GPT-6 Astra access depends on your subscription and the product area you use. Open AI’s current model documentation identifies Astra access through Work and Codex for eligible Plus users, while GPT-6 Pro, powered by Astra, is available in standard Chat for eligible Pro, Business, and Enterprise users.
Free and Go users should check the official Chat GPT plans and their model picker for the latest availability.
If Astra does not appear in your account, it does not automatically mean something is wrong. Your plan, workspace permissions, or the current rollout may affect access.
Chat GPT Plan Comparison
| Plan | Astra access |
|---|---|
| Free / Go | Check the current plan details; Astra is not listed as standard access |
| Plus | Work and Codex, subject to usage limits |
| Pro | GPT-6 Pro in eligible chats, plus Work and Codex |
| Business / Enterprise | Availability depends on the plan and workspace permissions |

How to Use Chat GPT Astra

Follow these steps to check your access and get started.
1. Update the Chat GPT Desktop App
Open the official Chat GPT desktop application and check for updates. If Astra is not visible, manually check for the latest version rather than relying only on automatic updates.
2. Open Work or Codex
If you’re using Plus, check Work or Codex instead of looking only in a standard chat. The available options depend on your subscription and account permissions.
3. Select the Available Model
Open the model picker and select the appropriate model if it is available to your account. Do not assume that every plan displays the same model options.
4. Start With a Small Task
Try a simple task first, such as asking for help with a code explanation, organizing a project, or preparing a research outline. Review the output before using it.
5. Use Codex for Coding Projects
If you’re working on software, use Codex to help with coding tasks. Keeping each project in a dedicated folder can make your files easier to organize and review.
6. Check the CLI Version
If you use the Codex command-line interface, Open AI’s Help Center specifies that Astra requires Codex CLI version 0.153.0 or newer. Check the official documentation for current requirements.
7. Verify Your Access
If you still cannot find Astra, check your subscription, workspace permissions, application version, and the current model availability information.
Using Astra Through the API
Developers can access the model using the API model ID gpt-6-astra. To get started, read the official GPT-6 Astra API documentation.
Do You Need a Separate App?
No. You do not need a separate application specifically for Astra. You can access it through supported Chat GPT interfaces when your account is eligible.
The desktop app may be useful for workflows involving Work or Codex. Developers who prefer the command line can also use the Codex CLI, provided their setup meets the current requirements.
Always download software from official sources and avoid entering API keys into untrusted third-party services.
How to Use Chat GPT for Free
Chat GPT offers a free plan through its website and mobile application. However, free access does not guarantee access to every model or feature.
To get started, visit Chat GPT and sign in. Check the models available in your account and review the current plan information before upgrading.
Be cautious of videos or websites promising unrestricted free Astra access through unofficial API proxies. Your prompts and other information may pass through a third party, and you may have no reliable way to verify how that service handles your data.
How Much Does GPT-6 Astra Cost?
The cost depends on whether you’re using Astra through a Chat GPT subscription or the API.
Chat GPT Subscription Costs
Within Chat GPT, Astra access is included in eligible subscriptions, subject to plan-specific usage limits. Check the official Chat GPT pricing page for current subscription prices and features.
Usage allowances may vary depending on your plan, workspace, model, and the complexity of your tasks.
API Pricing
According to the official GPT-6 Astra API pricing documentation, the standard text-token rates are:
Input: $10 per million tokens.
Cached input: $1 per million tokens.
Output: $50 per million tokens.
Requests containing more than 272,000 input tokens have higher rates applied to the full request. Check the official pricing documentation for the current multipliers and other billing conditions.
Here are two simplified examples using the standard input and output rates:
100,000 input tokens and 10,000 output tokens: $1.50.
300,000 input tokens and 10,000 output tokens: the cost is higher because the request exceeds the long-context threshold.
These examples exclude additional tool charges and other possible fees. Always verify the rates before estimating your project’s budget.
Why Can’t You See Astra?
If Astra does not appear in Chat GPT, check the following:
Your subscription: Confirm that your plan includes the type of access you want.
Your interface: Check Work or Codex if you have Plus.
Your app version: Install the latest available desktop app and update the Codex CLI if needed.
Workspace permissions: Ask your administrator whether your organization permits access.
Usage limits: Check whether you have reached your plan’s allowance.
You can find additional guidance in the Open AI Help Center.
If you still have trouble accessing the model, review the steps on how to use Chat GPT Astra and confirm your account eligibility.
When Is Astra Worth Using?

GPT-6 Astra is designed for demanding work, including software engineering, computer use, research, and multi-step professional tasks.
It may be useful when you need help with:
Creating an initial version of a website.
Understanding or debugging code.
Organizing a complex project.
Researching a topic using multiple sources.
Working through tasks that require several steps.
For a short email, a simple explanation, or a routine question, a lighter model may be sufficient. Your best choice depends on the complexity of the task, the time available, and your budget.
Regardless of the model, review the output carefully before publishing it or using it in an important project.
What Does Critical Cybersecurity Mean?
Open AI describes GPT-6 Astra as having reached its Critical cybersecurity capability threshold under its Preparedness Framework. This refers to the model’s level of capability in cybersecurity-related tasks, not a general guarantee that every output or interaction is safe.
Open AI has also described additional protections designed to reduce harmful cyber actions and unauthorized behavior. These safeguards do not eliminate every possible risk.
For important work, verify the output independently, avoid sharing sensitive information unnecessarily, and follow appropriate security practices.
