| Runs terminal commands | Yes | Yes |
| Multi-file edits | Yes | Yes |
| Git operations | Yes | Yes |
| Browser control | NoThe Browser capability and cloud browser belong to ChatGPT/ChatGPT Work, not to Codex cloud chats, whose containers only get configurable HTTP internet access (https://learn.chatgpt.com/docs/cloud/internet-access). | No |
| Sandboxed execution | YesEach chat gets its own container from the `universal` image, cached for up to 12 hours (https://learn.chatgpt.com/docs/environments/cloud-environment). | No |
| Multi-agent orchestration | Yes | YesEach task runs a coder and then a separate adversarial reviewer model that never saw the coder's session, and several tasks run at once. |
| Headless / CI mode | Yes | No |
| Models | ||
| Backbone | GPT-5.6 Sol, GPT-5.6 Terra, GPT-5.6 Luna | any |
| Bring your own model | NoThe Amazon Bedrock model-provider path is explicitly limited to local Codex surfaces and states that Codex cloud is not available (https://learn.chatgpt.com/docs/amazon-bedrock). | Yes |
| Local models | NoCloud chats run on OpenAI-hosted models only; the `model_provider` config that redirects inference is read by local clients, not by cloud containers. | No |

Which one would each critic pick
| Critic | Codex cloud | no_human | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.3 | 6.5 | Codex cloud — Pick Codex cloud if you already pay for ChatGPT and want to hand a task off from a GitHub pull request or a Slack thread and come back later; pick Jules if you live in the Google world. |
| El Crítico | 6.5 | 5.5 | Codex cloud — Each environment can be granted internet access and holds your secrets, so the agent is a container with your credentials and a network policy you configured once and forgot. |
| El Profesor | 6.8 | 6.8 | no preference |
| La Inversora | 8.0 | 6.0 | Codex cloud — OpenAI folded the Codex app into the ChatGPT desktop app in July 2026 and sells Pro from $100 with 5x or 20x limits; the coding agent is a retention feature for the subscription. |
| La Jefa | 7.0 | 5.3 | Codex cloud — Business is $20 per user, $1,200 a month for sixty, extra usage is credits priced per model, and there is an Enterprise tier, the shape procurement already knows from ChatGPT. |
| El Hacker | 3.5 | 7.3 | no_human — It ships an MCP stdio server on the official Python SDK, so my existing agent files a task with task_add and gets the whole loop behind it. |
