Why Codex CLI burns tokens

Codex CLI is autonomous — runs shell, edits files, plans across many turns. With GPT-5 Codex at $1.40/$11.20 per 1M, full-day usage hits $40-80 on OpenAI direct. Through us at 80% off: $8-15/day.

FAQ

Does Codex CLI support OPENAI_BASE_URL?

Yes. Codex CLI uses the OpenAI Node SDK under the hood and respects both OPENAI_API_KEY and OPENAI_BASE_URL. Point them at our proxy.

Can I switch between gpt-5-codex and Claude in the same session?

Codex CLI is OpenAI-formatted only — but our /v1/chat/completions endpoint routes Claude models too. Use --model claude-sonnet-4-6 if Codex CLI exposes a model flag, or stick with the GPT-5 family.

What about file edits + shell exec — is anything different?

No. Codex CLI executes shell and writes files locally. We only see chat completion calls. Everything else is unchanged.
