> OpenAI Codex (App-Server)
OpenAI Codex CLI — OpenAI's terminal coding agent (also web/IDE). Authenticates via ChatGPT OAuth or an API key. Model lineup (as of mid-2026): GPT-6 Astra, GPT-5.6 (Sol/Terra/Luna), GPT-5.5, GPT-5.4 / 5.4 mini, plus gpt-oss-120b; GPT-5.3-Codex-Spark is a Pro-only research preview. Plans: Free, Go ($8), Plus ($20), Pro 5x ($100) / 20x ($200); API-key mode is pay-as-you-go at API rates.
No token stored by OmniRoute. The Codex CLI app-server manages its own ChatGPT sign-in (~/.codex/auth.json, auto-refreshed). Use “Sign in with ChatGPT” if the CLI is not yet authenticated.
Free tier present — value not quantified
This provider offers a free tier, but its terms don’t convert cleanly into a USD figure (e.g. request-count limits or capacity-dependent pools). We refuse to print a misleading zero here. See the note below and the official pricing page for the exact limits.
note: ChatGPT plans use credit-based usage allowances (credits per 1M tokens, e.g. GPT-5.6 Sol 100/10/500); not a fixed $ credit value. API-key mode billed at standard OpenAI API token rates.
