What is config-codex-cli?

A step-by-step setup workflow for connecting the OpenAI Codex command-line tool to OmniRoute, an OpenAI-compatible backend.

Use it to detect the machine type, create Codex configuration and named profiles, set required environment variables, verify the connection, and configure session affinity for long-running work.

It removes the need to work out operating-system settings, shell commands, profiles, environment variables, and verification steps yourself.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00066	$0.00687
Opus 5	$0.00033	$0.00344
Sonnet 5	$0.00013	$0.00137
Haiku 4.5	$0.00007	$0.00069

Security

Grade A, and why

config-codex-cli scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Overview

Step-by-step agent workflow to configure the OpenAI Codex CLI on any machine (Linux, macOS, Windows) to use OmniRoute as an OpenAI-compatible backend. Detects OS and shell, writes config.toml and 7 named profiles, sets environment variables, and verifies the setup.

Quick install

npm install -g omniroute   # or: npx omniroute
omniroute --version

Long-running Codex tasks (#7287)

Two OmniRoute defaults silently break multi-hour Codex sessions. Document them whenever configuring Codex for overnight / multi-hour work. Full guide: docs/guides/CODEX-CLI-CONFIGURATION.md → Long-running tasks.

Session affinity (default off)

Setting: sessionAffinityTtlMs (ms; UI shows Affinity TTL (seconds) under Dashboard → Settings → Routing → Session affinity). Legacy alias: codexSessionAffinityTtlMs.
Default 0 = disabled. Each turn can land on a different account and break prompt-cache / session continuity.
Codex session keys (x-codex-session-id, x-session-id, x-omniroute-session, body prompt_cache_key / session_id) are only used for pinning when TTL > 0.
Max: 86400 seconds / 86400000 ms (24h). Set TTL above the expected task length (e.g. 43200 s for ~12h).

Stream idle timeout (default 10 minutes)

Env: STREAM_IDLE_TIMEOUT_MS (default 600000). Also consider FETCH_BODY_TIMEOUT_MS (same baseline; 0 disables).
Synthetic SSE heartbeats do not reset the idle clock — only real upstream chunks do.
A quiet reasoning turn past the idle window is force-closed (stream_idle_timeout / StreamIdleTimeoutError). Grep logs for Idle timeout: no data from.

Recommended multi-hour recipe

Dashboard → Settings → Routing → Session affinity → Affinity TTL = 43200 (12h) or 86400 (24h max).
OmniRoute environment:

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
