    Does that really mean that it's bundling those apps from the start or did it just download and install them at some point to do some local work on some prompt or job you ask it to?

    I don't see it making much sense to bundle it. I'm sure a LOT of LLM prompts are related with docs, excels, powerpoints etc, etc but don't really see it worth it for it to be bundled on the codex app from the get go, because otherwise, why not also install dozens of other apps?

      I'm not sure. Someone who hasn't installed the ChatGPT (or Codex) apps yet could confirm this by installing the apps, seeing if that ~/.cache directory exists, then try running a prompt that needs Python or Node.js or LibreOffice and see if it downloads them when needed.

        I've never installed the ChatGPT app on my Mac until today. I ran the app, signed in, and I see the same.

        % ls ~/.cache/codex-runtimes/codex-primary-runtime/dependencies/native/libreoffice-headless

        libreoffice manifest.json

          On a Windows installation I see this:

              PS C:\Users\user> ls C:\Users\user\.cache\codex-runtimes\codex-primary-runtime\dependencies\native\
              Mode                 LastWriteTime         Length Name

          So doesn't seem bundled with all installs at least.

      > why not also install dozens of other apps?

      because other apps are less likely to be useful, and there's diminishing returns

    Is that what it is using to render and manipulate MS Office documents? That'd explain the poor rendering of some of my files. Bundling all of LibreOffice seems like a pretty huge dependency.

      JLO64 44 minutes ago

      For a docker image of mine I was bundling the full version of LibreOffice as well but I managed to get some space savings by bundling just the no-gui version.

      What's the alternative library you see?

      tiahura 25 minutes ago

      Yes. If you have word you can instruct to use word via com or AppleScript.

      OutOfHere 30 minutes ago

      Just the headless version is bundled.

    Curiously, I didn't find any reference in the Open source licences section of the codex app.

    Is this a MPL 2.0 violation?

      thesdev 17 minutes ago

      Copyright violation is the last thing one could accuse ChatGPT of.

        vb-8448 3 minutes ago

        Well, this one is particularly obvious, other one are more fuzzy.

  • esperent 37 minutes ago

    I actually bundle it with my app too and the reason is reading files, especially old xls files. Since I'm bundling it I'm now using it for everything docs related but the specific reason is those old files. I couldn't find anything else that I could just drop it and feel confident it'll just read anything I give it.

  • jrflo 37 minutes ago

    I've noticed that when I have codex read/modify word files the live reasoning snippets often allude to LibreOffice, so that makes sense. I think it was a quick and dirty way for them to interface with docx and xlsx files?

      iAMkenough 37 minutes ago

      Who said it was a problem? This looks like an observation to me, not an accusation.

  • m3kw9 20 minutes ago

    probably uses it extensively to convert between LLM working on a doc and exporting it out to excel, word etc

    There's no security benefit to doing this versus demand-downloading hashed-locked components on need.

        Walnut is the .NET and OpenXML backend. I think the point parent was trying to make it that it shouldn't be surprising Codex bundles runtimes for damn near everything.

    I still don’t understand why with all their cash these companies dont redo their apps in Rust or native. They are all so heavy and dog slow. There are already some very fast cross platform (wasm too!) libraries that can do what poppler does as well as parse and produce various office file formats. Because 2gb is crazy town, these things could be around 100mb, just throw some tokens at the problem.

      sudo_cowsay an hour ago

      Not that easy. Also, they have "priorities." Although their priorities are different than the users'.

        cpursley an hour ago

        Just throw some tokens at the problem. I’ve vibed up a Rust Crux hybrid app that runs well on macOS, iPad and wasm and does some pretty complex xml manipulation and other document work. Absolutely smokes electron and you get native UI.

          doc_ick 18 minutes ago

          On top of everyone else’s great points, if you make your own “fork” of something, then you have to consistently maintain it. Which can be done with tokens, but an extra cost with something that’s not as user tested.

          verdverm 42 minutes ago

          one does not just "throw tokens" at a problem, Ai is not that capable, and we are talking about MS Office file format, likely a NP hard problem

            vb-8448 19 minutes ago

            But in case they succeed the return on image will be astonishing.

              doc_ick 13 minutes ago

              Can you expand upon this?

            sigbottle 37 minutes ago

            I mean, aside from all the NP Hard sub problems (I might not be reading your satire though), the real hard problem is that a "product" is not just software, but an ecosystem and a promise of maintenance of the abstract user experience & quality of it.

      nomel an hour ago

      What % of time, for a an average session, do you think is app overhead vs waiting for tokens? And there's your answer for why it's not a priority.

        andai 42 minutes ago

        Jon Blow's response to this take was, "yes, which is why you have to work even harder to hide latency", instead of adding more on top.

        From OpenAIs perspective, resources on your computer are free and wasting them is inconsequential

      What makes you think Rust is automatically better?

      (Also, "Rust or native" is a strange dichotomy. What's not native about Rust?)

        kennywinker 24 minutes ago

        I think “or native” is a gesture at swift/objc for mac and C# or whatever people write windows apps in.

  • alex-moon 42 minutes ago

    Someone may need to explain to me what is wrong with this sorry. Is it because it bloats the app with functionality that some users will never use? I feel like that is fairly usual for productivity/business apps generally.

      simonw 36 minutes ago

      I don't see anything wrong with it, I just think it's interesting.

        alex-moon 15 minutes ago

        Oh right, yeah I agree. It's the kind of thing I can imagine the harness downloading in the background anyway (or instructing the user to do) at some point so I can see the sense in just skipping that bit. Kind of comforting they just do it the same way the rest of us do - if it ain't broke and so on.

        nialse 26 minutes ago

        It does, however, introduce a potentially enormous attack surface into ChatGPT, along with creative opportunities for less security conscious individuals and LLMs.

        winstonp 28 minutes ago

        I think it's overbloating my computer

      OutOfHere 29 minutes ago

      Actually, people do use and require the functionality, which is the point. The title as posted might be incorrect.

        alex-moon 24 minutes ago

        Yes, that's what I mean - maybe that didn't come across cos I said "bloats". I work for a business that builds web apps for corporates - LibreOffice is bundled in most of the repos of ours that I've seen, a bit like Imagick is in the broader sector.
