Third-party works our engines are built on, with the credit their licences require.

No licence in service obliges a credit. These engines nonetheless run on third-party model weights, and are named here because whose data taught a model is a question a credit line does not answer:

• BiRefNet by Zheng Peng et al. (MIT) — MIT. Trained on DIS5K — academic dataset; the owner accepted the open question of whether its terms reach the MIT weights (2026-09-26).
• Real-ESRGAN by Xintao Wang et al. (BSD-3-Clause) — BSD-3-Clause. Trained on DIV2K, Flickr2K, OST — academic datasets; the owner accepted the open question of whether their terms reach the BSD-3 weights (2026-09-26).
