Why JEV is the right model here
A browser agent makes a decision at every step: which action next, given the current page. The post describes the architecture as a new action space every step, DOM state space, and a small LLM fallback for typing.
That is a stream of small choices, not a stream of essays. When the deciding is fast and cheap, the whole loop gets fast and cheap, and the agent stays responsive instead of pausing to think in paragraphs.
How to copy it
- List the decisions your workflow makes repeatedly at each step.
- Split them from the actions that need language generation.
- Decide fast and cheap, generate only when needed.
