RL researchers debate whether Dyna-style systems should be called models or world models

A reply-poll asks RL researchers whether they call a Dyna-like model-based RL component a “model” or a “world model.” The post pushes back on renaming existing concepts just to boost citations and recognition for a few labs.

It’s less about proposing a new method and more about the community’s terminology and incentives around naming in reinforcement learning.
