From the slop profile it's easy to see what are true foundational models and what are distills.

The only foundational models:
ChatGPT models
Gemini
Claude
Llama
Old mistral models (new ones are just ChatGPT 4o distill)
Old V3/R1 (new V3 is ChatGPT 4o distill, new R1 is Gemini distill)

Everything else is a distill.
