Codex

Good fit for

Developers moving between local repositories and cloud coding tasks while reviewing changes through a common agent workflow.

Why consider it

The product page documents code changes, browser/computer verification, cloud tasks and PR review; the official CLI repository verifies macOS/Linux/Windows installation paths.

Main limitations

The CLI is Apache 2.0, but that does not make hosted model inference free. A local program is not proof of local model inference. The exact current local-weights mode was not verified in this pass, so Runs Locally remains blank rather than being classified Online Only. Cloud services and the CLI have different execution environments.

Cost and access

Paid ChatGPT plan access and a separately configured API-key route are documented. No current free allowance is inferred. Exact regional prices and included usage are omitted.

Getting started

Choose the official CLI, IDE or cloud route, sign in with an eligible plan or configure an API key and start with a limited repository task. Review commands, diffs and tests.
