Codex App: Parallel Agents Review - Verdent AI

## 3 differences that immediately change adoption ### Only one model stack (today) vs multi-provider orchestration This is the biggest constraint. Codex currently uses: - GPT-5.2-Codex (standard model) - GPT-5.3-Codex (newest, announced February 5, 2026) **What you can't do:** - Route tasks to Claude Opus 4.6 for complex planning - Use Gemini for code search across large codebases - Switch to specialized models for different task types … ### No built-in editor loop (today): why jumping out matters during debugging/refactor Codex shows you diffs and lets you review changes. What it doesn't have: an integrated code editor for quick tweaks during the review process. **The workflow** reality: 1. Agent completes task → presents diff in Codex app 2. You spot a small issue (e.g., incorrect variable name) 3. Options: Ask agent to fix it (new round trip, 30-60 seconds) Open in VS Code, fix manually, come back (context switch) Stage the good parts, fix later (lose momentum) Compare this to tools like Cursor or the upcoming Xcode 26.3 agentic coding integration, which let you edit code inline during agent review. **The workaround:** For quick prototypes, this is fine. For serious refactoring where you're constantly tweaking details? The jump-out-and-back friction adds up.
