The useful distinction
Codex cloud: OpenAI's coding agent, running background tasks in isolated ChatGPT cloud environments. Included with ChatGPT plans. Not the 2021 Codex model.
Google Jules: an asynchronous coding agent that clones a GitHub repo into a short-lived Cloud VM, proposes a plan, and can open a PR.
Head to head
Buyer questions
| Question | Codex cloud | Google Jules |
|---|---|---|
| What runs | Codex agent. AGENTS.md for lint/test/review rules. | Jules, powered by Gemini (2.5 Pro on free; 3 Pro on paid, per Jules docs). |

Rush
Where Rush sits
Rush runs Codex from an API for a team. It does not run Jules or Gemini.
Honest limits
Skip Rush if
- Rush runs three agents: Claude Code, Codex and OpenCode. It does not host an agent you wrote yourself.
- Repositories come through the Rush GitHub App. A GitLab or Bitbucket repository cannot be a run's repository yet.
- There is no self-hosted or customer-VPC deployment, and we do not publish a compliance report today.
- Compute is metered. Free includes 5 agent-hours a month and Pro 40, each with a weekly ceiling.
- You review the pull request. Rush does not merge for you.
