Products that do what Unstock.ai – Free image generation with SDXL does

Hi HN! I've got the barebones of a service running on top of Stable Diffusion XL. I can cheaply run image generations at 1024x1024. And of course there's a limit to how fast I can generate them given the request queue and limited GPUs, but the service is cheap enough that I'm happy to run it out of pocket for now. Let me know your thoughts, I hope you enjoy the service!

    Hi HN, this is an early version of what we’re imagining as a truly functional stock photo platform using Stable Diffusion. We’re doing our best to hide the customization prompts on the back end so users are able to quickly search for pre-existing generated photos, or create new ones that would ideally work as well. If we keep going with it, in future versions we’d like to add voting, better tags, and more varied prompts, or maybe whatever you recommend!

    I've had a blast playing with stable diffusion and I see all the potential it will bring to us. I released a service for training your model, just upload 20-30 images and you can have a model of someone or some object doing anything. You can train one model for free a month in a slower queue or you can train many models on a fast queue and with other features for a fee. Here is an example of using it for show product placement: https://app.88stacks.com/image/O6kReClOvrz7 and here is an example of using it for people:…

    It's our new text-to-image model: a 9.3B single-stream diffusion transformer trained entirely from scratch. We focused heavily on controllability through structured JSON prompts, with strong text rendering, spatial awareness through bounding box guidance, and color palette control. It has the best text rendering of any open-weight model we've tested so far, and the NF4 quantized checkpoint runs on a single 24GB GPU. For more technical details and examples see our blog post: https://ideogram.ai/blog/ideogram-4.0/ We will be happy to answer any questions :)

    Hello HN, I built Bulk Image Generator because I was frustrated with how slow it is to iterate on visual assets. Tools like Midjourney are great for single images, but when you need 50+ variations of a product shot or a game asset based on a specific reference, the manual process is a pain. What it does: Upload one reference image and generate 100+ AI variations while maintaining style/structure. Batch background removal (because once you generate 100 images, you usually need to clean them up). Fast bulk download. Why I’m sharing it here: I’m looking for feedback on the consistency of…

    It works by using open AIs new gpt-image API, image processing algorithms and some prompt engineering. Still has some limitations, but can already generate ready to use assets.

    hey there hn! thought you would appreciate my brand new file format - i've spent over 40 minutes creating this standard. it's really hard trying to get your ideas shown to standards boards etc but i think with the great community here we can help get bioif support into all major browsers :) the spec is available over at the website, as is a reference implementation. it already has higher usage than jpeg-xl. - best

    Hey everyone - I'm currently building GenTube — the playground where creativity moves at lightning speed. We're making it possible for a billion people to create together instantly. Right now, we're offering unlimited, free generates - plus it only takes around two seconds per generate (much faster than Midjourney)!
