When to Use a LoRA vs a Fixed Model

An honest decision rule for choosing training, references, or a simpler fixed-model workflow.

Start with the output requirement

Use references and a fixed model when you need speed, broad scene variety, and moderate consistency. Training becomes useful when identity precision and repeatability matter more than setup time.

Count the content volume

A small campaign rarely justifies training. A long-running persona, repeated client work, or a local generation pipeline can justify the dataset and testing cost.

Treat training as infrastructure

A LoRA is not a magic identity switch. It needs a clean dataset, repeatable prompting, model compatibility checks, and quality control across every new workflow.
