I did reach out to Peng (the original author) before the release about license, citation, paper_url with specific emphasis on the the license part and got the green light from him to release the model under the original MIT license or the apache2.0 license since i have pushed for it. since this is a mistake from my part not iterating with the team about my comms i sincerely apologize for this and I have updated the model card to reflect this change to use the original MIT license, i will also update the library so that all models using the birefnet architecture will be released under the MIT license shortly. and thanks a lot for bringing this to my radar.
