Reference¶

The shared vocabulary and rules behind Lookhouse — written once here and linked from every Creator, Buyer, and Developer guide. If a term, base model, or license tier shows up in another page, this is where it's defined.

Start with What is a LoRA? if you're new, jump to the Compatibility matrix to check what runs where, or use the Glossary for a quick definition.

What is a LoRA?¶

A base model (SDXL, Flux, and the like) already knows almost everything — faces, fabric, sunlight, motion, depth. What it doesn't know is your particular person, place, look, or move. Retraining a billion-parameter model to learn one of those would cost a fortune.

A LoRA (Low-Rank Adaptation) is the shortcut. It freezes the base model and trains a tiny set of new weights that nudge it toward one specific thing — a thin overlay clipped onto a finished engine. The engine does the heavy lifting; the overlay steers it. Because the thing it adds is small, the file is small, and you control how hard it lands with a strength dial at generation time.

The payoff is consistency. Ask a raw model for "the same person" or "the same anime style" across ten shots and you get ten variations the audience can feel. A LoRA holds it steady, frame after frame.

The six LoRA types¶

The same set whether you're buying or selling. Each links to its full guide.

Camera Motion moves the camera within a single shot; a Transition moves between two shots. They pair well but solve different problems.

Base models & compatibility¶

Every LoRA is built for a specific base model — the foundation it runs on, whether a still-image model like SDXL or Flux, or a video model such as Wan. Matching matters: a LoRA delivers its quality only on the base it was built for.

You don't need a master list — compatibility is shown on every listing, and the right version reaches you automatically:

• Ordering a creator's character? You place the order and we build it for the base model your project uses, so it arrives ready for your pipeline.
• Buying a developer's upload? The listing shows exactly the version(s) the developer published — upload a Wan build, buyers see the Wan version. Pick the one that matches your stack.
• One subject, several bases. A single listing can carry the same subject trained for multiple base models; choose yours at checkout and get the matching file.

Rank, role, and how they map¶

Lookhouse organizes LoRAs by role — how large a part the LoRA plays in a shot — and role is read from the rank of the file. Because each type does a different amount of work, the same role maps to a different rank per type.

Three rules of thumb: DoRA at rank r ≈ plain LoRA at rank 2r with a smaller footprint (use it for premium tiers); rank 128 is rarely right — split into bundled lower-rank LoRAs instead; and test composition before listing, since buyers stack character + location + transition together.

Glossary¶

Base / checkpoint — the foundation model a LoRA is built to run on (e.g. an SDXL- or Flux-family model). A LoRA is matched to a base; the right one matters for quality.

LoRA (Low-Rank Adaptation) — a small set of trained weights that bolts onto a base model and nudges it toward one specific identity, place, look, or move.

DoRA — a LoRA variant that delivers comparable quality at roughly half the rank with a smaller weight footprint, so it composes more cleanly when stacked.

Rank — how much "room" a LoRA has to store detail. Higher rank holds more nuance but makes a larger file; well-tuned lower ranks are often sharper and more flexible.

Strength / weight — a dial at generation time. Turn it up to push harder toward the exact result; ease it down to let it blend.

Trigger word — a unique token (like a stage name) dropped in the prompt to call the LoRA into the scene.

Role — the scale of the part a LoRA plays in a shot: Background, Supporting, Hero, or Marquee.

Usage — how the buyer intends to use the output: Personal, Creator, Commercial, or Broadcast.

Studio — the Lookhouse web application where creators train LoRAs and buyers generate videos. Always capitalized.

Licensing terms¶

A license is set along two independent axes. The buyer picks one from each, and the combination sets the price.

Role — the scale of the part:

Usage — what the output is for:

Because the axes are independent, the same file can be licensed for a hobby project or a broadcast production without separate listings. Full detail lives in How licensing works.
