Measured

2026-10-31, Open Interpreter 0.0.56, the Rust version from the installer https://www.openinterpreter.com/install (Linux and macOS) and https://www.openinterpreter.com/install.ps1 (Windows), in the scenarios workflow (run 41151440753, and runs 41149533184 and 41153462586). The scenario was scenarios/first-run.sh interpreter interpreter and scenarios/first-run-windows.py interpreter interpreter, with no login. In the same jobs, Codex CLI 0.166.0 ran with the same scenario (facts 29, 53 and 62).

The GitHub releases of OpenInterpreter/open-interpreter have the tags rust-v0.0.56 and rust-v0.0.55. The Linux installer reads the variables OPEN_INTERPRETER_INSTALL_DIR or CODEX_INSTALL_DIR, and OPEN_INTERPRETER_COMMAND_NAME or CODEX_COMMAND_NAME. It installs interpreter, the alias i, and codex-code-mode-host in ~/.local/bin.

What was measured

  1. On ubuntu-24.04, Open Interpreter made ~/.openinterpreter/ with the same names as ~/.codex/ of Codex CLI 0.166.0: config.toml, installation_id, version.json, .tmp/plugins (5,434 files), .tmp/plugins.sha, .tmp/plugins.sync.lock, skills/.system, tmp/, and the SQLite files state_5, logs_2, goals_1, memories_1 and queue_1, each with -wal and -shm. Codex CLI made 49 files in skills/.system, Open Interpreter 62.
  2. The process held the five SQLite files with -wal and -shm open, and .openinterpreter/tmp/arg0/codex-arg0<random>/.lock. The lock folder of Codex CLI is tmp/arg0-linux/codex-arg0<random>/.
  3. The first screen has the layout of the Codex CLI screen: "Welcome to Open Interpreter", a sign-in text, a numbered menu "> 1. Sign in with ChatGPT", "2. Sign in with Device Code", "3. Provide your own API key", each with a line of help, and "Press enter to continue". Codex CLI 0.166.0 has a fourth option "Use Amazon Bedrock".
  4. The ten Linux and macOS labels gave the same bytes for the screen.
  5. On Windows, Open Interpreter made the same entries in the real %USERPROFILE%\.openinterpreter (21 changes), and none in the throwaway home, on the three images (fact 64).

Mechanism

The installer variables, the binary codex-code-mode-host and the file names show that Open Interpreter 0.0.56 is built from the source of Codex CLI, with the folder .codex renamed to .openinterpreter. The source was not compared.

A reader of Codex sessions can read the files of Open Interpreter with the same rules, in another folder. A tool that finds a process by the name codex or by a path with .codex does not find Open Interpreter.

Incident

None.
