Most AI browser agents today take 60–90 seconds to do the simplest tasks.

They screenshot the entire viewport, send megabytes of pixels to an LLM, guess X/Y coordinates, and pray the button didn't move.

The Browser Use team just open-sourced a total paradigm shift:

Meet Jev Ultrafast (browser-use/jev-ultrafast) ⚡🌐🤖

Finding & booking flights from Zurich → London on Google Flights in just 7.1 SECONDS flat!

Here is why its architecture is revolutionary: • Zero Screenshots in Loop: Eliminates heavy vision pipelines. It reads atomic DOM snapshots into an indexed action space table: [1] button, [2] combobox, [3] textbox. • Speculative Multi-Head Decisions: Predicts operation (CLICK, TYPE_TEXT) and target heads simultaneously in ONE network round trip. • Decoupled Text Generation: Small fast LLM writes text ONLY when the operation is TYPE_TEXT. Zero token waste on clicks or navigation. • 10x Fewer Protocol Calls: Slashes Chrome DevTools calls from 1,092 down to 101. • Built-in Freshness Guards: Verifies target visibility and prevents click occlusion without re-querying the model.
