Understanding VRAM Requirements
VRAM (Video RAM) is the most critical spec for AI image generation. Here's what you need for each use case:
- 4GB VRAM — SD 1.5 only with optimizations, slow, limited to small resolutions
- 8GB VRAM — SD 1.5 comfortably, SDXL with sacrifices, most popular models
- 12GB VRAM — SDXL comfortably, most LoRAs and extensions, good resolution
- 16GB VRAM — All current models, higher resolutions, multiple LoRAs simultaneously
- 24GB VRAM — Everything at maximum quality, fastest generation, future-proofed
The Real Cost of a Local AI Art Setup
The GPU is just one part of the cost. A complete local AI art setup includes:
- GPU: $500–2,000
- PC build (if needed): $400–800 additional
- Electricity: AI generation is power-hungry — 300-450W for the GPU alone
- Time: Hours of setup — CUDA installation, Python environments, model downloads
- Ongoing: Model updates, extension compatibility issues, troubleshooting
With Wurt.app, none of that applies. There is no card to buy, no PC to build and nothing to install. You pay per creation with credits, only when you make something.
Skip the GPU with Wurt.app
- No hardware to buy. Skip the $500–2,000 graphics card and the PC around it.
- Any device. Wurt.app runs in the browser on a Mac, a laptop or a phone.
- No setup. No CUDA, Python environments, model downloads or extension updates.
- Pictures up to 4K. Picwurt's 4K Normal mode makes 4K pictures, and you can upload a photo and describe the change.
- Video in the same account. Vidwurt turns text or a picture into video, with sound on supported models.
- Pay as you go. Credits, with no subscription and no hardware to pay off.
How to Start Without a GPU
- Open Wurt.app in any browser and sign in or create an account with an emailed code.
- Describe a picture in Picwurt, or upload a photo and describe the change. Pictures usually finish in under a minute.
- Animate it in Vidwurt if you want motion, or start a video from text.
- Download what you want to keep. Creations are deleted automatically after 7 days.
