@dalias @mirabilos @aredridel which still means that at best the generated code cannot be copyrighted, and at worst it violated copyright and license terms of the original authors (whose works were ingested to train the model). In both these cases, the resulting code cannot be incorporated into any FOSS project with any license.
Typically when people submit code to FOSS projects, they also (implicitly or explicitly) claim that they hold the copyright on the submitted code, and agree that this code will be licensed under the license the project uses (which they only have power to do if the first claim is actually true).
When LLMs are used to generate code, the first claim is false, and it _is_ a contamination.
