Yet Another Stable Diffusion Image Generator — a nod to the open-source habit of calling a thing "yet another" one, and to the many generators before it.

YASDIG makes pictures on your own computer, with your own graphics card. It is one file: no Python, no installer, nothing to set up. It's private: There is no account, no telemetry and no update checks. The drawing is done by stable-diffusion.cpp on Vulkan, so it runs on AMD, NVIDIA and Intel GPUs alike.

Why YASDIG: draft cheap, finish what's worth it

Most generators make you pick the expensive settings before you know whether the picture is any good. YASDIG turns that round:

  generate small and fast ──▶ keep the good ones ──▶ escalate only those
  (a batch, or a loop)        (every image is        Hi-res · Refine · Refine an area
                               archived with its      Edit · Extend · Upscale
                               settings)              ── each one a step you can undo

• Generate small and fast. Run a batch, or let it loop while you watch. Every image lands in the work-item grid with everything that made it, so any one can be reopened and taken further later.
• Escalate only the keepers, in the Refine & adjust dialog (a click on the picture opens it):
  • Hi-res makes it bigger and adds the detail a plain upscale can't invent.
  • Refine goes over the whole picture lightly, or paint an area to redraw just that part: a hand, a face, a sign.
  • Edit changes it by instruction ("make it night", "remove the hat"), with Flux.2 or FLUX.3 Klein.
  • Extend grows the canvas and draws what lies beyond the edges, with FLUX.1 Fill.
  • Upscale enlarges it with AMD FSR or an upscaler model, drawing nothing new.
• Any pass can use a different model. Draft on a fast Turbo model, finish on a detailed one.
• Every pass is a step in the picture's history. Go back with Ctrl+Z, or compare two steps side by side with a split you drag.
• Colour and sharpness are live and lossless. Eleven sliders (tone, colour, clarity and sharpness) work on the untouched original, so you can change your mind as often as you like, and nothing is ever redrawn over pixels that were already sharpened.
• Touch up by hand. Brushes (Dodge, Burn, Blur and more, plus Restore, which paints an earlier step back in), a selection by shape and colour with a look of its own, crop, and text drawn onto the picture.

Install

You need a 64-bit Windows 10 or 11 or Linux PC with a graphics card and an up-to-date driver; current AMD, NVIDIA and Intel drivers all include Vulkan. There is no macOS version.

1. Download the archive for your system from yasdig.com or the Releases page: yasdig-windows-x86_64.zip or yasdig-linux-x86_64.tar.gz.
2. Extract it somewhere you can write to — Documents, say, not Program Files. On Windows, right-click the zip → Extract All. You get a yasdig folder: keep it, everything the app makes goes in there.
3. Start yasdig in that folder. On Windows, the first start may show Windows protected your PC: yasdig is open source but not yet signed with a Microsoft certificate, so choose More info → Run anyway. (Started from inside the zip without extracting, it stops and says so: it would be running from a temporary folder Windows deletes.)
4. Your browser opens on the app. Open the Models tab and download a model — one click, with progress in the top bar's Downloads. The table below helps you choose.
5. Back on the Image tab, type a prompt and press Generate.

To stop it, close its console window or press Close server on the page. To update, replace yasdig.exe (or yasdig) with the one from the new archive: your models, settings and pictures stay where they are. The folder ends up holding:

yasdig(.exe)       the program
models/            the models you download (each subfolder has a README.txt)
user/              your settings and favourites — never cleared
work/              every generation, and work/output/ for the pictures you save
bin/               stable-diffusion.cpp, unpacked from the program
models.toml, startup.toml   start-up settings; rarely needed

How much graphics memory you need depends on the model: the table below gives what each takes on the card. With less than that, the Memory setting keeps the model in system RAM or streams it from the SSD, and when a render runs out of memory anyway, the error offers the ways out.

YASDIG is developed and tested on Linux with an AMD Radeon RX 7900 XTX (24 GB). Other Vulkan GPUs and Windows should work; reports are welcome.
