Checkpoint (base model)
A checkpoint is a complete, saved set of trained weights for an image model, essentially the file that contains everything the model has learned. Loading a different checkpoint changes the overall look and capabilities of your generations, since each one is trained on different data and can favor different styles, realism levels or subjects.
In tendre.AI there is no checkpoint to pick: every image renders with Krea 2, and its variants are chosen automatically from the prompt. The Components tab does not accept checkpoint files.
