The decision that matters

Start from the model and output workload. Workflow interfaces do not erase the memory cost of resolution, frame count, conditioning models, or upscaling.

Check these constraints

  • Largest graph you will run weekly
  • Required extensions and model ecosystem
  • Offload behavior and platform support
