Stanford NLP's Aryaman Arora disputes Greg Brockman's claim that Codex is open source, pointing to its proprietary underlying model
Brockman cited a terminal-based coding agent repository as evidence.
codex is open source in the same way google search is open source (i can hit view source on the frontend)
under appreciated that codex is open source
@theo i don’t have any issue, i’m very glad for my friends there to be making a ton of money.
“Codex” as a name is ambiguous enough as you have pointed out that it’s very silly to claim the veneer over the model that they have released makes Codex open source in any meaningful sense
Terrible analogy. The codex CLI and app server are fully open source, Apache licensed and available on GitHub. The Codex desktop app is not (this frustrates me) Models labeled Codex are not open weight, which appears to be your issue here? Weird hill to die on. Conclusion: they used the name “codex” too much and this post is dumb
@theo yes great. I am simply saying the harness being open source is such a silly basis for the sentence Codex is open source. the thing that makes Codex work is not open source.
@aryaman2020 Codex the model exists because they wanted better models for codex the cli/harness, which is open source. Grill them for overusing the name all you want. I can destroy your awful analogy with one link: https://github.com/openai/codex
@theo it’s of course very reasonable for them to do that, it’s just funny that that is what open source has come to mean now.

@aryaman2020 bad comparison

Codex is Open Source and you can learn a great deal about it just by pointing your codex to it
ask it how a feature X works, ask it how you can efficiently optimise your current setup
and perhaps my fav is seeing how team members building codex use codex
