Unstable Diffusion

Unstable Diffusion is a web image generator giving access to 120+ open source and lab models plus 40,000+ LoRA influences through one $30 per month plan, with unlimited use of everyday models and looser content restrictions.

Unstable Diffusion, operated under the UnstabilityAI name, is a web-based image generation platform that bundles a large catalog of models behind a single subscription. The catalog spans closed lab models such as GPT-Image, Seedream, Flux and Recraft, plus open source families including SDXL, Pony and Illustrious. According to the site, more than 120 models are available, alongside over 40,000 "influences" (LoRAs) that steer a model toward a style, character type or look. New models are added as they are released. The platform is aimed at people who have outgrown the filters of mainstream generators. Its pitch is that each model carries its own safety policy, so a user can swap to one that suits the project from the same prompt box instead of moving between apps. The testimonials on the homepage come from a freelancer producing ads for adult entertainment clients and from a Midjourney user frustrated by over-eager auto-filtering. Others use it for fantasy worlds, brand campaigns, key art, manga panels, logos and product stills, so it also serves general illustrators, marketers and hobbyists who want one place instead of several subscriptions. In practice the user picks a model, optionally layers influences on top, and iterates on prompts. Usage is split into two tiers. Everyday models have no cap and are never blocked, although generation priority can dip during peak load and recover afterward. Premium, compute-heavy models draw from a separate weekly pool that refills inside the monthly plan. The Pro plan costs $30 a month with a 30-day money-back guarantee, and Max plans enlarge the heavy pool by five to ten times. A free explore area lets visitors browse before paying. Among alternatives, it sits between closed services like Midjourney, which restrict content more tightly, and self-hosted open source setups that demand technical effort to run. The trade-off is that it is a hosted, subscription-bound service rather than a tool users control themselves.
