This article is a really good summary of current thinking on the “world model” conundrum that a lot of people are talking about, either directly or indirectly with respect to current day deployments of LLMs.

It synthesizes comments on “RL Environments” (https://ankitmaloo.com/rl-env/), “World Models” (https://ankitmaloo.com/world-models/) and the real reason that the “Google Game Arena” (https://blog.google/innovation-and-ai/models-and-research/go...) is so important to powering LLMs. In a sense it also relates to the notion of “taste” (https://wangcong.org/2026-01-13-personal-taste-is-the-moat.h...) and how / if it’s moat-worthiness can be eliminated by models.
