Earlier quoted context omitted.
The models were built using copyrighted works, so why can't models be built using other models?
Because model output is probably far closer to software or a licensed work which possibly has greater protections than it is to copyright. There is far less possibility of fair use, it might be protected by patents, license or reverse engineering laws. In any case the laws are being written now, but I doubt these will have worse protection than software does, which has far better protections than copyright
I mean otherwise it’s a very slippery slope, effectively it would give Anthropic the ownership of any code generated by its models..
