OpenAI Codex: delegate coding tasks, keep the review.
Codex takes a task, works in an isolated environment and proposes a code change. We choose suitable repositories and tasks with you, prepare the test environments and set the review rules.

When is it useful?
You already use ChatGPT
Codex is included in several ChatGPT plans. You still need to decide on which projects and under which rules.
A small development team
Two or three developers can delegate tasks in parallel, provided they review what comes back.
What we deliver
Repositories and tasks
The projects open to Codex, the kinds of tasks delegated and those that stay excluded.
Test environments
Dependencies, test data without real data, limited network access.
Project instructions
An instructions file (AGENTS.md): conventions, test commands, rules to follow.
Review before merging
What a person must check and which tests must pass.
For an SME: where to start
This work falls under our Engineering offer. For a small development team, a support subscription may be enough afterwards.

Points to watch
No real data in tests
The Codex environment holds no customer data and no production access.
Reviewing is still work
More delegated tasks means more code to review. We size the rollout to the team’s review capacity.
Internet access
A connected agent can download unvetted code. We limit access to the sources it needs.
Frequently asked questions
Is Codex included in ChatGPT?
Codex is available in several ChatGPT plans, with varying usage limits. We check your plan and the current terms.
Codex or Claude Code?
We compare both on your repositories and the same tasks: code quality, tests, cost and how easy they are to supervise.
Do we need GitHub?
Codex connects to GitHub to work on your repositories in the cloud; there is also a command-line version on the developer’s machine. We choose based on how you work.
Is Numezis an OpenAI partner?
No. Numezis does not claim any OpenAI partnership or certification. We advise and implement independently, and choose the tool for your work.
