What Stable Assistant is

Stable Assistant was a web-based chatbot for generating and editing creative media through conversation. It supported text-to-image creation, reference images, and image editing, and its product descriptions also covered video, 3D models, and music. Image generation used Stable Image Ultra, based on Stable Diffusion 3.5 Large. Listed image tools included generating images with the same structure, extending images beyond their original boundaries, enhancement, upscaling, sketch-to-image, and background removal. Text prompts could also create music, sound effects, and soundscapes; Stable Audio was described as producing instrumental tracks up to three minutes long at 44.1 kHz stereo. Chat features for writing and image captions used Stable LM 2 12B. The FAQ gave usage examples of 6.5 credits for a successful image generation and 0.1 credit per message. Stability AI said it might use inputs and outputs to improve its models, with an opt-out available. Personal data might be processed on US servers. The paid service had a three-day trial and was scheduled to sunset on October 1, 2026. Its URL and pricing path now redirect to Stability AI’s main website.
