The SMILE open source licensing is ideal for use cases such as Free Open Source Software ("FOSS") applications under the GPL that want to combine and distribute those FOSS applications with SMILE software, student/academic purposes, hobby projects, internal research projects without external distribution, or other projects where all GPL obligations can be met. Commercial License Usage OEMs (Original Equipment Manufacturers), ISVs (Independent Software Vendors), VARs (Value Added Resellers) and other distributors that combine and distribute commercially licensed software with SMILE must enter into a commercial license agreement with SMILE.AI, LLC. The commercial SMILE license gives you the full rights to create and distribute software on your own terms without any open source license obligations. With the commercial license you also have access to the official SMILE Support and close strategic relationship with SMILE.AI, LLC to make sure your development goals are met.
