Best AI Gateway to Route Codex CLI to Any Model

This article discusses routing Codex CLI to multiple AI models using an AI gateway. Bifrost is recommended as it has an 11 microsecond overhead and is open-source. To set it up, run 'npx -y @maximhq/bifrost' and configure environment variables or the codex.toml file. This allows Codex CLI to connect to multiple models without switching tools.
