Open a supported Codex client and sign in with your ChatGPT account. Clients include the desktop experience, terminal, IDE extension and web. Follow the setup instructions for the client you choose.
Start working
Describe a coding task in the context of your project. Review the changes and checks produced by the agent. Local and cloud workflows have different environment and workspace requirements.
Check usage and access
Allowances vary by plan, model and workload. Use the usage screen or limit notice to understand the available capacity. Cloud eligibility and workspace controls are separate from access to a local Codex client.
