# Uta! Studio GGUF models

GGUF model files loaded by the native GGML runtime of [Uta! Studio](https://github.com/bintis/uta-studio). Uta! Studio's Runtime Manager downloads them on explicit user confirmation; each file is published unchanged from the build that Uta! Studio runs.

These files are converted or repackaged from third-party upstream models. **Each model keeps its own upstream license and attribution**, listed below. This repository does not relicense any model. Check the upstream terms before use, in particular for non-commercial (`cc-by-nc-sa-4.0`) and unresolved checkpoint licenses.

The two BS-RoFormer Leap XE90 models are not mirrored here; Uta! Studio downloads them from [scragnog/HOT-Step-CPP-SuperSep](https://huggingface.co/scragnog/HOT-Step-CPP-SuperSep).
