An LLM is more like software than it is like media. The GPL defines source code as the preferred form for making modifications, including the scripts needed for building the executable from source. The weights in this case are more similar to the optimized executable code that comes out of a flow. The "source" would be the training data and the code and procedures for turning that into a model. For very large LLMs almost no one could use this, but for smaller academic models it might make sense, so researchers could build on each others' work.
