+- **Upstream model:** [UsefulSensors/moonshine-tiny](https://huggingface.co/UsefulSensors/moonshine-tiny) — published by `UsefulSensors`.
+- **Upstream licence:** `mit`. This repository redistributes under the same terms; it grants no rights the upstream licence does not.
+- **What was done here:** format conversion and/or quantisation only (GGUF/GGML). No training, no fine-tuning, no merging, no distillation, no change to architecture, vocabulary or capability. Only the numeric representation of the upstream weights differs.
+- **Training data:** documented — where it is documented at all — by the upstream provider; see the upstream model card. No training data was used, added or selected by this repository.
+- **Provider status:** under Regulation (EU) 2024/1689 the upstream authors remain the provider of this model. Converting the serialisation format does not make this repository the provider of a new general-purpose AI model, and no such claim is made. Questions about training content, copyright policy or model capability belong upstream.
