Jev Ultrafast

Browser Use's open-source ultra-fast browser agent harness powered by Jev decisions.

Overview & Result

An open-source implementation pairing Browser Use with Jev. It restructures the agent loop to compute actionable element subsets and offload decision-making to Jev.

How Jev fits in the loop

  1. Construct a bounded action space from current page accessibility tree.
  2. Invoke Jev to predict the next logical interaction.
  3. Fall back to lightweight generative models only when novel text typing is required.

How to reproduce

  1. Inspect the source implementation at https://github.com/browser-use/jev-ultrafast.
  2. Configure local Jev API credentials and register required tool/model bindings.
  3. Execute test prompts and observe decision latency and routing outputs.

Why this build matters

Serves as the reproducible foundation for high-speed, cost-effective browser agents.

Limitations

  • Metrics are author-reported from the initial release unless independently verified.
  • Requires access to the respective agent framework or runtime environment.
  • Generative model execution remains external to the Jev decision step.
