A Research Preview of Codex

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

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

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

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?

Next week: OpenAI rebrands Windsurf as Codex.

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

Codex IDE. Calling it.
