Effectively all models can do style transfer reasonably well at this point, but not so much for "actual reasoning".
If the combination of two works better for you than each one by itself, why wouldn't you stack them like that?
Wash, Rinse,,, Repeat?
whats going on is openai and anthropic have tons of garbage in their system prompts "don't talk about goblins" so your ability to override that garbage is nearly wiped out. This is "alignment" and I'm pretty sure both orgs have convinced themselves that this benefits the customer.
