Codex guides

How to run a non-OpenAI, OpenAI-compatible model inside the official Codex App on an isolated profile, with its own credential, model list, and reasoning effort.

Guide · 2026-08-22

Point the official Codex App at an OpenAI-compatible aggregator so one connection serves many models, each with its own transport and reasoning behavior.

Guide · 2026-08-22

What works, what does not, and how a custom-provider profile lets the official Codex App run on a model you supply.

Guide · 2026-08-22

Why a fixed low / medium / high list is wrong for most models, and how effort values are resolved from provider metadata instead of guessed.

Guide · 2026-08-22

What a custom-provider profile actually does, why it is not a billing bypass, and the terms you are responsible for reviewing.

Policy · 2026-08-22

Stop logging out of Codex just to change accounts. Save multiple profiles, switch the active one locally, and keep work, client, and personal sessions separate.

Profiles · 2026-05-22

Manage multiple Codex CLI profiles safely. Learn how to save Codex profiles, rename them, and rotate between accounts for rate limit management.

Profiles · 2026-08-22

Run several OpenAI logins in one desktop app, or bind a profile to an OpenAI-compatible provider. Switch Codex CLI accounts without re-auth.

Accounts · 2026-08-22

CodexUse warns when multiple profiles resolve to one OpenAI identity. Learn why it appears and how to handle duplicate Codex profiles.

Profiles · 2026-05-22

Accounts Pool turns selected saved Codex accounts into one local API with shared quota, load balancing, and failover for another app.

Accounts Pool · 2026-08-22

Connect another OpenAI-compatible app to Accounts Pool so it gets one local API, pooled quota across selected accounts, load balancing, and failover.

Guide · 2026-05-22

Set CodexUse Pro auto-roll's Switch, Rejoin, and Alert lines - all a percentage of quota left - so profiles hand off before Codex stalls on a 429.

Auto-roll · 2026-08-22

Use CodexUse cloud sync during an active trial or with Pro to push from your main machine and pull profiles, config.toml, and settings on another device.

Cloud Sync · 2026-08-22

Orchestrate Codex App windows with profile-matched accounts, plus Codex CLI profiles, rate-limit headroom, and safe restart behavior in CodexUse.

Codex Apps · 2026-08-22

Codex usage guide: installation, authentication, basic commands, configuration. Learn how to use the Codex CLI effectively with real examples.

Basics · 2026-08-22

Where Codex keeps model, reasoning effort, approval policy, sandbox mode, and MCP servers, and how each CodexUse profile gets its own config.toml.

Settings · 2026-08-23

Add MCP servers to Codex by editing config.toml by hand, and keep each CodexUse profile's servers isolated from every other profile.

MCP · 2026-08-23

Use the CodexUse CLI to switch profiles, manage Accounts Pool, and sync profile data without opening the desktop app.

CLI · 2026-05-22

Install CodexUse with Homebrew, verify the CLI landed in PATH, and update cleanly with the official cask workflow on macOS.

Homebrew · 2026-05-22

How CodexUse handles updates, restarts, and installers. Learn Apple Silicon macOS support, the 2.5.8 manual upgrade step, and where to download.

Updates · 2026-08-22

Historical Linux workflow note for CodexUse CLI users. Desktop releases target Apple Silicon macOS, but CLI profile workflows still apply on Linux.

Linux · 2026-05-22

Understand Codex rate limits, why 429s happen, and how to see profile headroom before long runs stall. Switch profiles before sessions fail.

429s · 2026-08-22

Codex not working? Work through auth, rate limits, network, config, and version in that order. Most failures clear in minutes without reinstalling the CLI.

Triage · 2026-08-22

Codex keeps asking you to log in again? Fix expired or revoked login state, refresh the right profile, and get back to work without deleting your local setup.

Login · 2026-08-22

An honest comparison of CodexUse against codex-lb, codex-switcher, codex-pool and other free Codex account switchers: what each does, what none of them do, and when not to pay.

Comparison · 2026-08-22

Compare CodexUse, CodexBar, and vanilla Codex CLI by account switching, rate-limit visibility, local control, and background help.

Comparison · 2026-08-22

Where multiple Codex accounts are ordinary, where they cross into terms abuse, and exactly what CodexUse does and does not do with the accounts you hold.
