Browser Use Opens BU Ultrafast in US

Browser Use has made BU Ultrafast available on every US Browser Use Cloud plan, including the free tier. The company reports a 22-second median task time at $0.0064 per task, with access enabled by setting `model` to `bu-ultrafast`.

// ANALYSIS

BU Ultrafast makes browser agents far more practical for high-volume automation, though the “fastest and cheapest” claim remains vendor-reported and excludes browser and proxy charges.

–Runs GPT-6 Luna on OpenAI’s priority tier for lower latency
–Requires no API redesign—developers only change the model parameter
–Company data shows over 12,000 Ultrafast runs across 134 projects
–`bu-fast` remains available when tasks need more reasoning per step
–The US-only rollout limits the meaning of “everyone” for international teams
