| # Third-Party Licenses & Attributions |
|
|
| emu is a proprietary product of CloudKites Pty Ltd (see `LICENSE`). It bundles or |
| downloads the third-party AI models and software components listed below, each |
| used under its own license. The notices in this file are provided to comply with |
| those licenses and are part of the emu End-User License Agreement. |
|
|
| emu does **not** modify the third-party model weights' architectures; the models |
| are run for inference and, where noted, quantized for on-device efficiency. Where |
| a license requires that modifications be indicated (e.g. CC-BY-4.0), quantization |
| and format conversion to emu's bundle format are the only changes made. |
