Can I use Codex CLI with an OpenAI-compatible endpoint?

Yes. AnyRoute is designed around familiar API shapes and route aliases, so teams can keep client code predictable while changing the upstream model route.

Does this page replace the backend product app?

No. The public site explains routing, setup, pricing, and migration choices. API keys, billing, and account state remain owned by the backend product app.

How should I choose a production model?

Start with the route that matches your workload, then compare latency, quality, cache behavior, and fallback requirements before exposing it to users.

All tools

Codex CLI

Codex CLI can use AnyRoute as a stable gateway while keeping the API key, model route, and fallback rules explicit.

Primary surface: cli

Recommended route: gpt-5.5

Start with gpt-5.5 for this workflow, then compare latency, quality, and cost before making it the team default.

Setup boundary

Keep the AnyRoute base URL, API key, and model route in environment variables or the client settings supported by the tool.

Use a backend-owned API key or team-managed secret.

Keep billing and usage inspection in the product app.

Document the active route before adding fallback behavior.
