IMPORTANT: MODEL WEIGHTS ARE NOT COVERED BY THIS LICENSE
===========================================================================

MATA is a software framework only. It does NOT distribute, bundle, or
include pre-trained model weights. When you use MATA to load a model —
whether from HuggingFace Hub, a local file, or any other source — that
model's weights are governed by their own separate license terms.

You are solely responsible for ensuring that your use of any model weights
complies with the applicable license for those weights. Common licenses
encountered include (but are not limited to):

  - Apache License 2.0           (e.g., DETR, RT-DETR, GroundingDINO, SAM,
                                        Depth Anything V2, Mask2Former)
  - MIT License                  (e.g., CLIP)
  - Tongyi Qianwen License       (e.g., Qwen-VL series — commercial use
                                        requires additional acceptance)
  - Meta Community License       (e.g., LLaMA-based models — usage thresholds
                                        and restrictions apply)
  - Creative Commons BY-NC       (non-commercial use only)
  - GNU GPL / AGPL               (copyleft — derivative works must be
                                        open-sourced under same terms)

Some models on HuggingFace Hub require you to agree to additional terms
before downloading. By using MATA to load such models you acknowledge that
you have read and accepted those terms independently.

MATA makes no representation or warranty regarding the licensing terms of
any third-party model weights accessed through this framework.
