    It’s sad how the existing corpus of artists’ works are being used against them.

    The only reason this can generate images like these is because artists previously created artwork like this. And then in return they get:

    > you don't need to high an artist or animator to develop you game.

    Unless you created all the training material yourself, any model like this is highly unethical, in my opinion.

    • archerx 4 hours ago ago

      As someone who is an artist and also a programmer I find the differences between both very different. I never see programmers crying over A.I. chiming “they stole our code so it’s evil and I’ll never use it and neither should you!” Like the artist seem to do.

      I don’t really care if the image gen models are trained on my renders or photos as long as they are open source.

      Also I have been making the assets for my game which needs at least 2,000 sprites and honestly it’s very tedious and I’m looking to automate as much of the pipeline as I can so I welcome anything that removes the the tedium and pain from the process.

        From a recent blog shared on HN, among a list of reasons they can’t or won’t use LLMs:

        >The training data for LLMs is stolen. I don’t mean like “pirated” in the sense where someone illicitly shares a copy they obtained legitimately; I mean their scrapers are ignoring both norms and laws to obtain copies under false pretenses, destroying other people’s infrastructure.

        people did complain about it stealing GPL code scraped off github etc and then license laundering a lot, especially during the earlier days. I think now people are just worn down to have the conversation again.

        I do also think the threat is bigger to artists. Sloppy code will cause problems, and at some point you'll need someone who knows what's going on to step in. Sloppy art, a lot of people accept.

      • davidweatherall 2 hours ago ago

        I think there's a big difference with how designers and programmers can use AI to enhance their work, and how exploited the average person's work has been. A lot of designers publish their work on social media, or it's visible on their websites etc., which AI models have used to train with. But with coding, most people's code only exists in private repos, or is compiled to a format that LLMs cant easily be trained on.

        • archerx an hour ago ago

          There is so much code on github and all the other repos that it can compare with the amount of art that is out there. Also all of your Javascript code is public once your site is published.

          There is nothing stopping artists from using A.I. to improve their work. The sketch to image work flows are great, the variation work flows can save from the tedium and inpainting can help fix and improve images.

          Text to image is lazy and is the cause of most of the slop but no one is saying artist should replace their Wacom tablets with text prompts. I feel like there is a lot of hurt egos going on. I remember back in the day on CGtalk, there was so much elitism and in hindsight it probably held a lot of people back, myself included.

      • nkrisc 44 minutes ago ago

        I’m not opposed to generative AI, in principle, it’s how it’s being employed that bothers me.

    • akritrime 23 minutes ago ago

      Imagine if writers complained that stuff they wrote were being used in literature classes that teaches people how to read and write because how sentences they once toiled over for hours would now be used in mundane letters.

      AI can't take away an artists creativity, just like how photography didn't kill painting. Yes, it closes up certain avenues on how artists make money but it will most probably make up for that by making them more productive.

    • Aeolun 5 hours ago ago

      Unless you didn’t want people to see and use it, maybe you shouldn’t have made it public? I don’t think training AI is fundamentally different from humans learning from things they see, and we don’t restrict that either.

      • fourside an hour ago ago

        When it’s big copyright holders we have very specific, very granular definitions of what constitutes fair or allowed use. But when it comes to smaller creators the answer is that it’s their fault for trying to promote their work and make a living.

      • wrasee 5 hours ago ago

        The fundamental difference is that computers can do this at a pace and scale that humans could never aspire to. There is a natural limit to the extent a single individual can be informed by previous works. It sets a natural pace to innovation that is sustainable for both the artist and derivative works.

        Computers have no such limitation and can consume almost the entirety of a subject’s work in a few weeks or months. I think that alone is enough to say that yes, it is fundamentally different.

        • jason_oster 2 hours ago ago

          Automated assembly lines have the same properties. Same with transportation. Buses, trains, airplanes, ships. These all work tirelessly at a pace that humans cannot match.

          There is no fundamental difference.

          • wrasee an hour ago ago

            I think you missed the point. The claim is that AI training from public information is no different from humans learning from public information.

            My argument is precisely that the mechanisation of information is fundamentally different from the scale at which a human can learn. One immediate consequence being there is no longer a natural brake on the scale of what can be sourced for use in a derivative work.

            To be clear this is not a value judgement, just to point out that it _is_ different, just as driving is fundamentally different from what one can do with one’s own feet. Of course the mechanisation of transport is history and seems daft to argue against. But it is different. Whether that’s good or bad is a much harder question.

      • nkrisc 44 minutes ago ago

        AI isn’t human.

      • bnop 5 hours ago ago

        1. These models have been trained on private data many a time without permission

        2. Making something public isn’t always a choice made by the creator

        3. Making something public does not denote fair use, this is why copyright (albeit arguably a poor solution) exists

        4. These LLMs consolidate wealth into a small group using outputs from a larger, often less wealthy group (creatives) without fair compensation

        • dr_dshiv 5 hours ago ago

          These LLMs primarily distribute intellectual and creative wealth from media conglomerates to anyone on earth with $20. (Without fair compensation, agreed)

  • akritrime 21 minutes ago ago

    Is this using OpenAI's GPT-image or something different?

  • palmfacehn 11 hours ago ago

    Great progress. Bookmarked.

    For purposes of generative worlds, I have an additional requirement for interchangable equipment and weapons. I.e. a single sword or armor sprite should fit with all humanoid characters, in all animations. I suspect this could be achieved by training against "clipping" tests.

    As a start, there should be projections for all four cardinal directions.

    Limit the output to palettes of a given size, for classic recolors via GL shaders.

    • lyogavin 10 hours ago ago

      Thanks for so many valuable points and ideas. Will do.

      I like the "interchangable equipment and weapons." idea, very cool. And yes. it's doable. many ways possible could work. I'll experiment.

  • Cloudef 7 hours ago ago

    Not sure about professional quality. All the results seem to need quite bit of hand editing to look good. Also the examples only show animations ripped from street fighter.

  • doctorpangloss 18 hours ago ago

    There is a lot of negativity on Hacker News.

    Staying focused: the panda is wearing gloves, but then when it does the Hadouken and the Hurrican Kicks, it loses the gloves.

    Bigger picture this seems like a focus on product stuff like pricing and demos and navbars that don't really matter to artists or game developers. Your feelings are correct that people here - the root motivation of the negativity - are questioning your sincerity. With AI art this is acutely true, people don't view AI art as a sincere art endeavor. I don't doubt your sincerity. But spending more time on the art thing, and making it free or open source, it's going to look and feel more authentic.

    • themanmaran 12 hours ago ago

      I think the negativity is overkill.

      I've been toying around with the exact same idea the last couple weeks. It's mostly GPT 4o image => some image cleanup, but honestly a lot more finicky than I originally expected. Lots of prompt engineering. So OP probably put in a fair bit of effort here.

      Also each animation probably costs $1-$2 in GPT costs to make [1], so not something that's easy to throw a free tier on.

    I’m curious if you know of a similar tool for generating tilesets for top down RPG like games? I’ve tried Midjourney, which makes nice art, but it can’t be used in a game.

      sorry for the inconvenience.

      I've fixed it.

      ALso given your account 2x more credits.

      • taytus 7 hours ago ago

        Shouldn’t it be more like 5x credits? That’s what I would have given to a paying early adopter dealing with these annoying issues.

  • MasterScrat 5 hours ago ago

    Congrats on shipping!

    I’d love to hear a bit about the ML side of things: what was your experience with various models? Do you see a clear cost vs quality tradeoff with current state of the art models? How do open vs closed models compare?

  • elpocko 19 hours ago ago

    What model(s) does this use? Is it built using open source models and tools? I couldn't find any mention of models in the FAQ (who even asked those questions?) or elsewhere. I doubt you trained your own diffusion model.

    The GitHub cat in the footer does not link to GitHub either.

  • nurettin 2 hours ago ago

    It kind of does what it says on the can, but you will have to edit the result frame by frame in order to make the lost scales and equipment consistent across all animations. Still, a huge time boost.

  • sambeau 6 hours ago ago

    This is so depressing.

    Also, why does the female ninja suddenly grow a penis?

  • bitwize 16 hours ago ago

    Hand-drawn animation, whether for video games or television or other media, is one of those artistic fields where I can see AI being a huge win for everybody. The reason why is because drawing the in-betweens in an animation is tedious, time-consuming, costly, and, in most 2D animation productions, outsourced to sweatshops abroad. And yet it's most of the work that goes into an animation. I think most animators would rather just do the keyframes and leave the tweens in the hands of the machine. It'd make traditional animation as easy and fast as Flash animation, and create a flourishment of even more indie animations from solo creators with even higher quality.

  • okkdev 9 hours ago ago

    I hate this. It's cool that it's possible, but I hate it. Generating art solves no real problem and only suppresses a struggling profession without which this wouldn't even be possible...

    • miohtama 9 hours ago ago

      The problem is that in the indie game market, where most 2d sprites are drawn, there is not enough money going around making many studios profitable. By reducing cost of manual 2d animation, more studios can be profitable and able to deliver better, more finished, games. Then studios can pay decent salaries to employees.

    • makerofthings 9 hours ago ago

      Have to agree. I don’t think we should stop ai progress, just that I think we built a bad thing along the way. I will never buy a video game that I know has ai generated content, I want to see some art, not a soulless prediction of what art might look like.

      • petesergeant 8 hours ago ago

        > I will never

        Bet you $10 that in five years' time you will have.

        • makerofthings 4 hours ago ago

          It's not really practical but I would take the bet that I will never /intentionally/ buy a game with AI generated assets. I just don't see that AI generated art has any value to it. I'm sure you could sneak some past me, it's getting harder to spot all the time.

          • petesergeant 3 hours ago ago

            My guess is that in five years’ time there won’t be any games that don’t include any, and also people will really have stopped caring so much

    • Aeolun 5 hours ago ago

      I think the problem is that the profession is struggling because you pay a lot of money for work that is often of very dubious quality.

      I can’t ask a anyone that claims to be a pixel artist for sprites because the chance of getting garbage is just too high.

      Btw, if anyone does know someone good, I’m open to paying xD

    • yreg 5 hours ago ago

      > Generating art solves no real problem

      It definitely does solve a problem. This tool provides affordable custom sprites with fast delivery.

      If it didn't solve any problem there would be zero demand for it and no reason for you to care about it.

    • graynk 4 hours ago ago

      > solves no real problem

      this is very obviously not true.

  • highway900 16 hours ago ago

    > This isn't putting anyone out of work. The games simply would not be made in the first place.

    The opposite is also true. Games that should never be made are being made due to the rubbish that can be generated by these tools. Observe the generated samples on the landing page, they are literally just copying street fighter. These tools are so useless without ripping off the hard work of humans. The deluge of slop is a signal to noise problem.

  • iandanforth 19 hours ago ago

    All AI tools I've tried have failed to generate animations for slimes in my experiments. (Including Veo3) I'm hesitant to even try this, any chance it would work?

    • Aeolun 5 hours ago ago

      I really want to see an example with a slime. I’m sure it’d butcher it, but it would be so funny.

    • kevingadd 11 hours ago ago

      You're going to have a much harder time getting good animations generated for something that isn't a humanoid, since the training sets won't have much to work from. It's possible with a really good prompt for 'slime' you could get something but this doesn't seem to allow prompt customization.

      If you're after monsters like slimes I would not drop money on this.

      • Madmallard 10 hours ago ago

        Lol it's not functional for most things.

        I uploaded a photo of a pixel art electrician and it just completely ruins it and looks nothing like my guy and forces it into a particular style where it looks like a cheap mobile game playable ad and somehow Mario at the same time. Not to mention, the actual animation is wrong too.

  • 9283409232 19 hours ago ago

    It's cool but you can tell the sprites are low quality and AI generated. They have that trademark AI "fuzziness." It's possible that players would think it is a design choice but it is noticable.

    • lyogavin 17 hours ago ago

      will add a quality upscale model to fix it. thanks.

  • educasean 19 hours ago ago

    The example sprites aren't loading for me. I see original panda and the female ninja graphics, but the 6 sprite boxes are empty.

    You wouldn’t happen to have vibe coded this would you? I can’t get a response from multiple pages.

  • thrance 11 hours ago ago

    The samples on the landing page are... not good, by any metric. The background jitters, details go missing from frame to frame, and the animations that should cycle (run, walk...) don't look like they do.

    This is a prototype, at best. I would be ashamed of asking money for providing such a sloppy service.

    Also, in your faq you have "You own the rights to your generated content.", which I don't think is true. AFAIK, you can't copyright AI art.

  • mclau157 19 hours ago ago

    really the space for 16x16 sprites with AI has not been done very well so far

    • Dwedit 17 hours ago ago

      miaomiaoPixel_v11 can generate sprites that small. Specify a size of 128x128, and that corresponds to an actual size of 16x16. Use an image editor to shrink the sprite down to 16x16, then reduce the palette as needed to remove the near-matching colors.

      16x24 sprites end up looking a lot nicer though.

    Curious idea, but doesn't seem to working for me. It's been sitting in "Your job is in queue" state for 10 minutes, and that's it. Reloaded the page just now and it just reset itself.

    • lyogavin 17 hours ago ago

      sorry, I didn't expect so many requests all queued up too long. I've added some servers it should start to process.

      When your request finish it'll send you an email notification.

    The privacy pages and legal pages don't link. They all return to the homepage.

    Without them I am hesitant in uploading my concept art from my project for testing.

    Otherwise it is a cool concept and I would potentially look in to if it turns out you don't go all evil villain and claim ownership over the sprites.

    Enabling a preview set of sprites without having an account would do no harm neither.

    But creating an account without any legal documentation is a no from me as I don't know whats happening with my IP which leaves me uncomfortable.

    Even if it's not a ratified legal document; some draft is better than nothing.

    • lyogavin 17 hours ago ago

  • Madmallard 13 hours ago ago

    I'm surprised posts like this aren't instantaneously flagged and removed. The tools for doing this are readily available for free as it is.

    This is basically another "throw AI in it" CRUD app that wants your money. They're all really low effort grifts that do not deserve to see the light of day.

    They work for a subset of animations that go in commonplace game types. Anything creative or new or different? No chance you'll get a satisfactory result. They are all subtly wrong in ways that anyone can easily spot and will likely get your game filtered out and harshly criticized publically on Steam or other platforms.

    This right here too is so egregious: https://www.godmodeai.cloud/plans
