Presets and LoRAs#

A preset is a recipe: a base model plus the encoders, VAE, adapters and LoRAs it needs, with tuned defaults. Image Studio applies a model's default settings when you pick it; Video Studio picks everything through presets. This page covers both, plus LoRAs.

Model defaults in Image Studio#

Every main model carries default settings in the model manager: steps, CFG or guidance, scheduler, size, VAE. Selecting the model on the Generate tab applies them; edit them in the model's panel on the Models tab so your preferred values load every time. Catalogue models ship with sensible defaults; imported models start empty and use the family defaults.

Video model packs#

The video Models page (Video Studio, left rail) lists the Vireo presets: for each one, the slots it needs (transformer, text encoder, VAE, LoRAs, upscalers) with a per-slot file report: found, missing, or changing. A missing slot shows the expected locations, in root search order, and a copy button for the path; catalogued components have an install button. The starter models dialog installs the whole LTX set and the MiniMax H3 reference-to-video pack (two official sources are downloaded and merged on your machine). Copy a file into one of the listed locations and refresh the report from disk.

Custom presets#

Change a slot and save the result under a new name to derive a custom preset. The base preset is untouched; the custom one appears wherever presets are chosen and sends its slot assignments to the runtime with each generation. Preview before saving: a slot that shows as missing is rejected before the job enters the queue. Deleting a custom preset never touches model files.

Custom presets are how you swap a checkpoint variant (FP8 for bf16), try a different upscaler, or bake a LoRA into a preset for a project. Character sets are a special case built for you; see Character sets.

LoRAs#

A LoRA is a small add-on that steers a base model towards a style, a subject or a person. It only loads with the base model it was trained for.

  • Images: add LoRAs in the Generate panel and set a weight each. Style LoRAs sit around 0.6 to 0.8; identity LoRAs often want less. A LoRA panel shows its trigger phrases, which go into the prompt.
  • Video: shoot and scene LoRA lists take video LoRAs from the video LoRA library; character LoRAs from Training Studio land there automatically and default to strength 0.5, which is proven for MiniMax H3. Strength 1.0 breaks motion and lighting.
  • Edit tab: the Identity Edit LoRA for Krea 2 is required and chained automatically; see Edit.

Install image LoRAs from the Models tab like any model; trigger phrases can be recorded in the model panel so the prompt box suggests them.
