“It runs on DeepSeek, Claude, Gemini, Grok, OpenAI and Qwen, so it is the only thing in this industry with no strong opinions.”

Which one would each critic pick
| Critic | Ante | Codex CLI | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.0 | 8.0 | Codex CLI — If you already pay for ChatGPT, this is the terminal agent you have and it is a good one; open source, MCP, headless, and pointed at OpenAI until you configure it otherwise. |
| El Crítico | 6.3 | 7.0 | Codex CLI — A sandbox mode you choose once is the only barrier between the agent and your shell, the free tier is a taste, and the defaults point at one vendor. |
| El Profesor | 7.8 | 6.3 | Ante — Terminal-Bench 2.1 at 82.7 percent, reported as 368 of 445 trials across 89 tasks at five trials each, for roughly 68 dollars of inference, under the official constraints. |
| La Inversora | 6.8 | 8.3 | Codex CLI — A lab's terminal agent bundled into a $20 subscription with 121,000 stars on the repo; the distribution is ChatGPT, and that is the whole thesis. |
| La Jefa | 6.0 | 7.3 | Codex CLI — Business at $20 a seat with SAML SSO and no default training, Enterprise for SCIM and audit logs; if the org is on ChatGPT already, this is a line item, not a project. |
| El Hacker | 8.8 | 5.8 | Ante — Apache-2.0, MCP servers attach, and the built-in llama.cpp engine runs a GGUF file with no API key and no network at all, which is the whole argument. |
