Why Run SD 3.5 Here

The model is free to download. What is not free is the disk, the GPU and the hour of setup.

The Whole SD3 Family, Loaded

26 SD3 and SD3.5 checkpoints and 12 LoRAs are hosted and selectable — 3.5 Large, Large Turbo, Medium, and the community fine-tunes built on them.

What You Can Do With It

Generation is the first step, not the whole job.

feature 1

Text to Image at Full Resolution

Prompt SD 3.5 Large for detail or Large Turbo for speed, at the aspect ratio you need. Its rectified-flow architecture was built for multi-subject prompts and legible text in image, the two places earlier Stable Diffusion versions struggled.

feature 2

Edit What You Generated

Inpaint, outpaint, upscale, swap a background or fix a face — without exporting the image to another tool and losing the generation parameters.

Add LoRAs, or Train One

How it works

Three Steps, No Setup

Nothing to download and no hardware to buy.

step 1

Pick SD 3.5

Choose 3.5 Large, Large Turbo, Medium or a community fine-tune from the model list.

step 2

Write the Prompt

SD 3.5 follows long, specific prompts well — describe the scene rather than stacking keywords.

step 3

Generate and Refine

Iterate, then upscale or inpaint in place. Outputs land in your gallery.
