OpenAI Codex
Pros
- Included on every ChatGPT tier, including Free

Cons
- Token-credit metering makes cost harder to forecast than a seat

- Agent output still needs review before it touches production
- openai.com blocks non-browser fetches — a nuisance for link audits, not buyers
Which should you choose?
GitHub Copilot is built around developers; OpenAI Codex leans more toward engineering teams already on chatgpt business or enterprise. Shortlist the one whose strengths line up with your biggest constraint.
