Models

Maystro generates with open-weight models that are downloaded to your machine. Model weights come under their own licenses; the app ships the code, you decide which weights to use.

The starter set

During installation Maystro fetches a curated starter set: image models for Image Studio, the video model packs for Video Studio, and the encoders they depend on. The download is large (tens of gigabytes) and runs in the background; you can start using a studio as soon as the models it needs have arrived.

Optional bundles live in the Models area (top bar, next to the studios): the MiniMax H3 reference-to-video sources on the Video tab and the Assistant models (a voice/tool model and a larger writer model, see Assistant) on the Assistant tab. Install them when you need them.

Open Models in the top bar to see what is installed: the Image tab is the model manager, the Video tab lists each video preset's model slots with a per-slot file report, so a missing file is visible before you queue a job. See Models.

Where model files live

All model files live under a single models root, chosen at install time. You can point the root somewhere else later (a bigger drive, a shared folder) and add extra roots for your own checkpoints. See Models root and your own models.

Adding your own models

Drop checkpoints and LoRAs into the matching folder under a models root, or import them from the Image tab of the Models area. Assign them to preset slots to build your own presets; see Models and presets.
