    "Exclusively for research purposes" so not actually open source.

    • ffsm8 1 hour ago
      The readme doesn't claim its open source either from what I can tell. Seems to be just a misguided title by the person who submitted it to HN

      The only reference seems to be in the acknowledgement, saying that this builds ontop of open source software

      There's no reason to believe that weights are copyrightable. The only reason to pay attention to this "license" is because it's enforced by Apple, in that sense they can write whatever they want in it, "this model requires giving ownership of your first born son to Apple", etc. The content is irrelevant.
      • _alternator_ 39 minutes ago
        This. Tables of numbers are explicitly not subject to copyright; that’s a copyright 101 fact.

        Any of the code that wraps the model or makes it useful is subject to copyright. But the weights themselves are as unrestricted as it gets.

          You could make the same mocking argument towards people who find anything good that Apple produces.
    • andy99 1 hour ago
      Meta’s campaign to corrupt the meaning of Open Source was unfortunately very successful and now most people associate releasing the weights with open source.
      • Blackthorn 1 hour ago
        It's deliciously ironic how a campaign to dilute the meaning of free software ended up getting diluted itself.
        • sho_hn 1 hour ago
          It's gratifying. I used to tilt at windmills on HN about this and people would be telling me with absolute condescension how the ship had sailed regarding the definition of Open Source, relegating my own life's work to anachronism.

          People slowly waking up to how daft and hypecycle misusing a term was all along has been amazing.

          • archerx 1 hour ago
            The wildest one is how people say just because you produce open source software you should be happy that multibillion dollar corporations are leeching value from your work while not giving anything back but are in fact making your life harder. That’s the biggest piss on my back and tell me it’s raining bullshit I ever heard and makes me not want to open source a damn thing without feeling like a fool.
            • coliveira 57 minutes ago
              I think exactly like this. If I created a tool and it were used for free by billion dollar corporations to enrich themselves, I would consider it a personal loss.
      • isodev 17 minutes ago
        And the training data. A truly open source model also includes the training data.

        Releasing weights is fine but you also need to be allowed to... Use the model :P

        FOSS = free and open-source software

        Open Source =/= free or software, just readable

        so it wasn't a new campaign, it is at best re-appropriating the term open source in the software community in a way communities outside of software have always been using it, in a way that predates software at all, exists in parallel to the software community, and continues to exist now

        • ghurtado 19 minutes ago
          In 30 years in tech, I have never once heard anyone use the term "Open Source" to refer to anything other than FOSS.

          I have also never once heard anyone use the term FOSS outside of the written form.

          So the opposite of what you said, I guess.

          You also seem to be saying that the term "open source" existed before software did, so I feel compelled to ask: what do you think "source" stands for in "open source"?

          • jfengel 8 minutes ago
            "Source" can mean any source of information. The term "open source intelligence", referring to public records, goes back to the 60s.

      Interesting, the main license doesn't mention the limit, maybe that's why the op got confused

      • eleventyseven 1 hour ago
        Pretty sure this is a joke, but the actual license is written by lawyers who know what they are doing:

        > “Research Purposes” means non-commercial scientific research and academic development activities, such as experimentation, analysis, testing conducted by You with the sole intent to advance scientific knowledge and research. “Research Purposes” does not include any commercial exploitation, product development or use in any commercial product or service.

      Should the title be corrected to source-available?
      • RobotToaster 57 minutes ago
        "weights-available" is probably the correct term, since it doesn't look like the training data is available.
        • ecb_penguin 33 minutes ago
          Training data is not source code so that's irrelevant

    • littlestymaar 16 minutes ago
      Your daily reminder that neural network weights aren't creative work and as such aren't subject to copyright protection in the first place. The “license” is purely cosmetic (or rather, it's being put there by the ML scientists who want to share their work and have to deal with the corporate reluctance to do so).
    • echelon 2 hours ago
      That sucks.

      I'm writing open desktop software that uses WorldLabs splats for consistent location filmmaking, and it's an awesome tool:

      https://youtube.com/watch?v=iD999naQq9A

      This next year is going to be about controlling a priori what your images and videos will look like before you generate them.

      3D splats are going to be incredibly useful for film and graphics design. You can rotate the camera around and get predictable, consistent details.

      We need more Gaussian models. I hope the Chinese AI companies start building them.

      • wkat4242 29 minutes ago
        Making 3D worlds like that is impressive. I used to build some VR worlds (hobby) and content generation is a huge time sink. I wonder if this tech will become accessible for that soon.
    • hwers 2 hours ago
      I don’t agree with this idea that for a model to be open source you have to be able to make a profit off of it. Plenty of open source code licenses doesn’t require that constraint

        • ecb_penguin 28 minutes ago
          While most people follow the OSD criteria, there is nothing that says open source software must follow it. Nor is the OSD the only set of criteria or the only definition.

          Open source means the source is available. Anything else is just political.

          • nativeit 10 minutes ago
            Now you get to graduate into the pedantry of defining the word “source”.
      • Aachen 2 hours ago
        That's source-available: you get to see the code and learn from it, but if you're not allowed to use it however you want (with as only common restrictions that you must then credit the creator(s) and also allow others the same freedom on derivative works) then it's not the traditional definition of open source

      The authors appear to be all foreign-born.

      Just curious for those who are informed on this matter... are most research done by foreign born people? What happened to the big STEM push?

      I don't mean to stir up political debate... just curious what the reality is, especially given the decline in foreign students coming over in recent year.

      • foota 49 minutes ago
        I'm not trying to be too pc, but you can't really tell based on someone's name where they were born.

        That said, the US only has some 5% of the worlds population (albeit probably a larger proportion of the literate population), so you'd only expect some fraction of the world's researchers to be US born. Not to mention that US born is an even smaller fraction of births (2.5-3%, by Google), so you'd expect an even smaller fraction of US born researchers. So even if we assume that we're on par with peer countries, you'd only expect US born researchers to be a fraction of the overall research population. We'd have to be vastly better at educating people to do otherwise, which is a longshot.

        Obviously this makes turning away international students incredibly stupid, but what are we to do against stupidity?

      • onion2k 20 minutes ago
        are most research done by foreign born people

        Approximately 96% of the world's population is not American, so you should expect that really.

      • saagarjha 49 minutes ago
        1. People with foreign sounding names may have been born in the United States.

        2. People who were born outside the United States but moved here to do research a while back don’t suddenly stop doing research here.

      • raphman 40 minutes ago
        FWIW, many of the researchers on the paper did not study in the U.S. but immigrated after their PhD studies.

        I checked the first, middle, and last author: Lars Mescheder got his PhD in Germany, Bruno Lecouat got his PhD in France, Vladlen Koltun got his PhD in Israel.

        Apple is also a global company and has offices and research labs world wide. At least a couple of the authors seem to work for Apple but at their German lab.

      Curious what this has to do with the post?
      • lvl155 45 minutes ago
        Apple trying to “open-source” something is pretty relevant. I don’t trust them at all. People constantly go at Microsoft but what Apple has done in the last 15 years is far worse. Their monopolies have had far worse impact than whatever Microsoft ever did with Windows and IE.
        • wkat4242 28 minutes ago
          Yeah Apple was on a good track for a while with things like OpenCL. But completely reversed course :(
        • saagarjha 33 minutes ago
          What would you suggest they have done here?
        • AnonymousPlanet 15 minutes ago
          I decidedly disagree with about everything you said regarding Microsoft. The Microsoft monopoly is the most life sucking cancer the corporate world has ever experienced. Compared to that the entire existence of Apple is merely a footnote. Don't mistake your stupid phone for the world.
          • lvl155 4 minutes ago
            I sunk my twenties involving the sh*tshow that was Microsoft antitrust. No, Microsoft shipping IE by default is pretty benign compared to what Apple has been doing for far longer than whatever Microsoft ever did. In fact, one can make an argument that Windows was really an open platform for developers based on Today’s standards.

        Where does Swift fit into this? I haven’t followed along but believe it’s open source and a search appears to confirm this?
        • lvl155 39 minutes ago
          Swift language is open source but the entire ecosystem is as closed as they get. The fact that no one is building anything outside of the ecosystem says everything about Swift and Apple’s intent. The fact that they still won’t support Linux on M chips also says they don’t care.

    I was thinking of testing it, but I have an irrational hatred for Conda.
    • optionalsquid 2 hours ago
      You could use pixi instead, as a much nicer/saner alternative to conda: https://pixi.sh

      Though in this particular case, you don't even need conda. You just need python 3.13 and a virtual environment. If you have uv installed, then it's even easier:

          git clone https://github.com/apple/ml-sharp.git
          cd ml-sharp
          uv sync
          uv run sharp

    I’ve been using some time off to explore the space and related projects StereoCrafter and GeometryCrafter are fascinating. Applying this to video adds a temporal consistency angle that makes it way harder and compute intensive, but I’ve “spatialized” some old home videos from the Korean War and it works surprisingly well.

    Is this the same model as the “Spatial Scenes” feature in iOS 26? If so, it’s been wildly impressive.
    • alexford1987 1 hour ago
      It seems like it, although the shipped feature doesn’t allow for as much freedom of movement as the demos linked here (which makes sense as a product decision because I assume the farther you stretch it the more likely it is to do something that breaks the illusion)

      The “scenes” from that feature are especially good for use as lock screen backgrounds

    "Sharp Monocular View Synthesis in Less Than a Second"

    "Less than a second" is not "instantly".

    • ethmarks 1 hour ago
      What would your definition of "instantly" be? I would argue that, compared to taking minutes or hours, taking less than a second is fast enough to be considered "instant" in the colloquial definition. I'll concede that it's not "instant" in the literal definition, but nothing is (because of the principle of locality).

        Wittgenstein, Philosophical Investigations, §88:

        > (...) Now, if I tell someone: "You should come to dinner more punctually; you know it begins at one o'clock exactly"—is there really no question of exactness here? because it is possible to say: "Think of the determination of time in the laboratory or the observatory; there you see what 'exactness' means"? "Inexact" is really a reproach, and "exact" is praise. (...)

    Ah great. Easier for real estate agents to show slow panning around a room, with lame music.

    • tim1994 2 hours ago
      For panning you don't need a 3D view/reconstruction. This also allows translational camera movements, but only for nearby views. Maybe I am overly pedantic here, but for HN I guess thats appropriate :D

      It will be used for spatial content, for viewing in Apple Vision Pro headset.

      In fact you can already turn any photo into spatial content. I’m not sure if it’s using this algorithm or something else.

      It’s nice to view holiday photos with spatial view … it feels like you’re there again. Same with looking at photos of deceased friends and family.
