    What was the training data? While there are open source projects for mainframes, most high-quality and battle-tested COBOL code bases are likely proprietary.

    Also, will it be trained on the code base it sees? Most companies would be opposed to sharing their IP.

    Edit: according to the website, the model won't be trained with your data.

    How about mainframe systems using PL/I instead of Cobol?

      We have tried REXX and Assembler and they work decently, but have yet to try PL/I.

      That’s what we’ve seen with our customers. Some have only one or two COBOL developers left in some teams, and they are often the only people with the operational knowledge needed to keep these systems running.

      They are either past retirement or about to retire in the coming years.

      and now they moved to microservices chaos and need it more than ever.

    Is this available to install on Hercules emulator for hobbyists? For people unfamiliar with Mainframes, check out the moshix youtube channel.
    • aayn6 hours ago
      We don't currently support Hercules, but we are providing free access to a mainframe for people to try out.

    Hopefully Llm while it may not allow immediately for like 100% ready to go financial services code

    Maybe it gives us good tests ?

    That alone for something on cobol might be worthwhile

    > Mainframes still run a surprising amount of critical infrastructure: banking, payments, insurance, airlines, government programs, logistics, and core operations at large institutions. Many of these systems are decades old, but they continue to process enormous transaction volumes because they are reliable, secure, and deeply embedded into business operations.

    It saddens me when companies abandon them, it takes so much effort to replicate their power. I often wonder why mainframes never had a more modern easier to maintain and manage programming language designed for them.

      Although COBOL is one of the primary programming languages for the mainframe, it can also run Java and Python as the others have mentioned. COBOL itself isn't particularly difficult to grasp for modern engineers, it's readable and has an easy to understand English-like syntax.

      The challenge here is learning and becoming proficient in the end to end mainframe ecosystem including the intricacies of z/OS. It's a completely closed off ecosystem and is not as accessible to play around with for the average SWE as compared to windows or linux based development.

      Java is available on z/OS.

    Built by leading minds behind the world's most advanced AI and technology - Our team unites top researchers, engineers, and strategists from pioneering companies and institutions [...]

    https://www.hypercubic.ai/company

    Please consider adding more background of the executive and heads of department on the about page to help us understand who these top researchers, engineers, and strategists are.

    There are currently no names on the about page, not even the co-founders, however this claim that "our team unites top researchers, engineers, and strategists from pioneering companies and institutions" appears on multiple pages on the website.

    It seems:

    * Sai was an Apple machine learning engineer for 19 months, then a Apple lead machine learning engineer for 17 months.

    * Aayush was an Apple software engineer for 3 years, then an Apple senior software engineer for 8 months at Apple.

    • aayn3 hours ago
      Hi! I agree we should have a profile page on website.

      Btw, this is Aayush and I was at Apple for almost four years and Sai was there for three. And we have Kevin as our founding engineer who has almost a decade of experience and has worked at Cognition and Windsurf.

      • cube003 hours ago
        > And we have Kevin as our founding engineer who has [...] worked at Cognition and Windsurf.

        Kevin was at Cognition as a software engineer for 9 months and Windsurf as a design engineer for 7 months.

        Including company logos on the Hypercubic website because team members worked there for less then a year doesn't convey the endorsement of these companies I'd expect when I see their logo being used.

        • beachy2 hours ago
          I came here to agree with this. You don't put IBM's logo on your page just because one of your team used to work there.

          That gives off a bad signal to someone visiting your site.

          Everyone's faking it till they make it but at the same time using a logo like that, which universally implies that you have some kind of relationship with that company or they are using your product, is not even faking it.

          And that's ignoring the legal challenges you are up for if that company spots you doing it.

          BTW this sounds like a genius offering

          • dangan hour ago
            I was concerned when I read this, and was going to suggest that they consider changing it. But I just looked at the page and it seems clear in context. That section of the page is describing their team, and the text is talking about where they've worked previously. It's true that the logos imply some relationship, but in this case the relationship being implied is that of former employer.

            Had the logos been on their frontpage with no explanation, the implication would be that these companies are customers, but there's no such implication here.

            (Btw, I appreciate that you're saying this from a place of actually liking the product, or at least the idea, - I think it's often true that criticisms are coming from a place of wanting to like something, but commenters usually don't make this bit explicit and then the criticism just sounds like harshness for its own sake.)

            • beachy12 minutes ago
              I went back and looked again and while I have moved a little more to your position, I still believe it is misleading. The key text to me is "Our team unites top researchers, engineers, and strategists from pioneering companies and institutions—all focused on building systems that deliver real impact." Under that are the logos. To me, that implies that engineers who are actively employed by those companies are somehow working on this, the assumption being that those employers have blessed it.

              I'll admit it's not clear cut - but I feel it deliberately pushes the boundaries, as marketing often does.

              But as far as the idea goes, it sounds like a fantastic direction. That should have been my primary message.

    If it ain't broke, don't fix it. So letting an LLM loose on a mainframe is like letting a fox into a henhouse. :)
    • sai184 hours ago
      The problem here is that people who understand these systems are all retiring. Majority of the devs are over 60 and there's simply not enough new talent coming in to replace them.

      So the real challenge companies are facing is will there be enough people to safely maintain these systems in the next decade. If they do not, it means failures in credit card systems, airline reservations, insurance claims and more.

      • decidu0us90344 hours ago
        It sounds like they will still need to hire and train human talent who can understand the code, and evaluate and integrate outputs of AI systems that conform to the specific compliance and data retention requirements of these industries. And also people who can enforce said compliance, and a lot of other things. Sounds like a complex problem without a neat off-the-shelf solution

        Correct, they are retiring, for sure.

        The last thing I’d ever put into mission-critical systems is an LLM.

        So let’s hope it’s a mainframe sandbox so future COBOL programmers can learn on it. :)

        In any case, COBOL systems work precisely because no one is constantly tinkering with them to “add a new framework”.

        The last time I saw, someone made a “Hello World” app in Electron, and it was 220 MB.

        Howgh.

      • goatlover3 hours ago
        Wouldn't the lack of supply drive up wages until more new talent is incentivized?
        • sai182 hours ago
          That is the current landscape today. Mainframe engineers are in high demand and good ones are paid quite well.

          I've heard from a global bank, they have one mainframe developer in the team who is past 70. She manages a critical credit card service and gets paid in the upper end of 6 figures to work 20 hrs a week. She's the only one who knows that system. Lots of stories like this.

        Yawn this tired old yarn, again. Mainframe development was offshored from the US decades ago. These retiring cobol programmers simply don’t exist in numbers that matter. The market could be to the companies doing the offshore work, but they’ve been throwing bodies at this problem for a long time, maybe there’s a market there maybe not.
