It's time to make `codex-mini-latest` the new default, as this should be an "evergreen" model pointer. * Equivalent change in TypeScript https://github.com/openai/codex/pull/951 * See some notes about using `codex-mini-latest` with MCP in https://github.com/openai/codex/pull/961
codex-core
This crate implements the business logic for Codex. It is designed to be used by the various Codex UIs written in Rust.
Though for non-Rust UIs, we are also working to define a protocol for talking to Codex. See:
You can use the proto subcommand using the executable in the cli crate to speak the protocol using newline-delimited-JSON over stdin/stdout.
