It says: This constitution is written for our mainline, general-access Claude models. We have some models built for specialized uses that don’t fully fit this constitution; as we continue to develop products for specialized use cases, we will continue to evaluate how to best ensure our models meet the core objectives outlined in this constitution.

I wonder what those specialized use cases are and why they need a different set of values. I guess the simplest answer is they mean small fim and tools models but who knows ?
