Maddening: "codex" is also the name of their open-source Claude-Code-alike, and was previously the name of an at-the-time frontier coding model. It's like they name things just to fuck with us.


So -- that client-side thing is _technically_ called `codex-cli` (in the parent 'codex' repo, which looks like a monorepo?).

Still super confusing, though!

I feel like companies working with and shipping LLMs would do well to remember that it's not just humans who get confused by this, but LLMs themselves... it makes for a painful time, sending off a request and noting that a third of the way into its reasoning that the model has gotten tow things with almost-identical names confused.


they also have a dual implementation on rust and typescript there's codex-rs in that monorepo


more excited about the rust impl than the typescript one.


Besides packaging of their releases, what possible difference could that make in this problem domain?


I just think it's nice to have open source code to reference so maybe he meant just in that -educational- way, certainly more to learn from the rust one than the TS one for most folks? even if the problem-space doesn't require system-level safety code indeed


If it's name is 'codex-cli' then that means "Codex Command Line Interface" so the name is absolutely codex.


Next week: OpenAI rebrands Windsurf as Codex.


Codex IDE. Calling it.


VS Codex


And with themselves and their models. The Codex open source had prompt to disambiguate it from the model.
