Research direction
Start at the Codex CLI interactive /model picker and the model catalog data used to populate its quick entry. Compare the displayed codex-auto-review name and description with the catalog visibility and metadata. Done means the picker no longer presents a hidden model as a normal option, or clearly shows the intended model and matching description.

Description
Description
The Codex CLI model picker exposes codex-auto-review as the quick model and displays the description:
Balanced agentic coding model for everyday work.
That description belongs to gpt-5.6-terra in the official model catalog. The catalog describes codex-auto-review as "Automatic approval review model for Codex." and marks it with visibility: "hide".
The same picker simultaneously shows:
All models (current) ... (current: gpt-5.6-terra)
This makes it appear that codex-auto-review is a normal, selectable everyday coding model and creates uncertainty about which model and pricing apply.
Screenshot evidence
A user-provided screenshot shows this exact model picker state:
Select Model
Pick a quick auto mode or browse all models.
1. codex-auto-review Balanced agentic coding model for everyday work.
2. All models (current) Choose a specific model and reasoning level (current: gpt-5.6-terra)
Screenshot dimensions: 945 × 186 pixels. No private information is visible.
Steps to reproduce
- Start an interactive Codex CLI session.
- Open the model picker with
/model. - Observe the quick model entry.
Actual behavior
codex-auto-review is visible as a user-selectable quick model and is paired with the GPT-5.6 Terra description.
Expected behavior
The quick model entry should display gpt-5.6-terra if Terra is intended.
Alternatively, if codex-auto-review is shown intentionally, it should use its catalog description and clearly indicate that it is the internal automatic approval reviewer. A model whose catalog visibility is hide should not appear as a normal user-facing coding-model option.
