ThinkDiffusion is a cloud platform that runs the open-source generative AI toolbox — AUTOMATIC1111, ComfyUI, Fooocus, Forge and Kohya — on a dedicated GPU machine in your browser, so you get pro-level Stable Diffusion and FLUX workflows with zero local hardware or installation.
Instead of a simplified generator, ThinkDiffusion gives you the real applications, exactly as installed locally, on a private machine that only you can access. Workspaces are persistent (up to 200GB of storage), so your models, extensions, settings and outputs are waiting when you return. You can upload checkpoints, LoRAs and embeddings in one click from Civitai or Hugging Face, run several machines at once, and even work from a phone. Brands, agencies and universities use it for campaigns, fashion design and teaching.
The platform also maintains its own flagship model, ThinkDiffusionXL, tuned for photorealism and rated 4.7/5 by the Civitai community, and a large free learning centre with workflow guides for techniques like ControlNet posing, sketch-to-image and video generation. Case studies on the site span whisky and car brands, film productions and fashion schools — a sign that the same workspaces serve both first-time experimenters and professional art departments that need open-source freedom without an IT project.
Because the machines are dedicated rather than shared queues, long ControlNet chains and high-resolution upscales run at full speed, and simultaneous machines let a small team parallelise an entire campaign’s worth of generation.
The Hobby tier is pay-as-you-go with GPU time from $0.99/hour and free sign-up time to try the platform. TD-Pro runs $19.99/month billed yearly ($29.99 monthly), and TD-Teams for studios and classrooms is $59.99/month.
ThinkDiffusion is for AI artists, studios and educators who want the full open-source workflow — custom models, ControlNet, training — without buying or maintaining a high-end GPU rig.
