VLA vs World Models: Which Will Prevail?

Tue, 04 Aug 2026 00:00:00 +0000

Between 2025 and 2026, two distinctly different technical directions have emerged in robot AI. One is the VLA (Vision-Language-Action) approach, represented by RT-2, OpenVLA, and pi-0. The other is the World Models approach, represented by DreamerV3, Genie, and DIAMOND.

Many colleagues have asked me: between these two directions, which one should I bet on? My answer is: the question itself is wrong.

In today’s article, I want to break down and compare these two approaches, explain the logic, advantages, and bottlenecks of each, and then discuss why I believe they will ultimately converge.

If you’ve been following the latest developments in AI, you may have noticed a trend: from ChatGPT to Sora, from AlphaFold to robotic manipulation, AI is moving from “understanding language” to “understanding the world.” At the heart of this transition lies an increasingly central concept — the World Model.

In today’s post, I want to discuss, from an engineer’s perspective, what a world model is, why it matters so much for robotics, and what DreamerV3 — currently one of the most representative approaches — actually does.
