3D Generation VRAM Planner
A planning aid that keeps official requirements separate from community optimizations and avoids presenting a theoretical estimate as a compatibility guarantee.

Community workflow required
Expect quantization, offload, lower resolution and version-specific setup. This is not the official standard path.

Why no yes/no promise?Peak memory changes with model build, attention backend, quantization, offload, texture stage and wrapper version.
Use it in four steps
- Choose a model
- Enter available VRAM
- Select a workload
- Verify against the linked upstream documentation
Why memory estimates vary
Peak use depends on software versions, attention backend, intermediate tensors, resolution, texture stage, precision, and whether components are offloaded.
