what is a VLA model in robotics?

The idea inherits the large-language-model recipe: instead of programming 'how to fold a shirt', you show thousands of examples and the model learns the pattern. Figure calls Helix the VLA that drives its Figure 03, and the commercial teleoperation of the 1X Neo is exactly a factory for those examples: every chore an operator performs in a real home is a training demonstration the customer pays for.

The term matters for reading the news critically: when a maker says its humanoid 'learned' a task, the questions are how many demonstrations it took, whose they were, and whether it performs in new environments or only where they were filmed. The difference between a VLA that generalizes and a rehearsed demo is the difference between the three levels of teleoperated vs. autonomous.
