Browser Use Benchmark Tests Seven Harnesses

Browser Use compares seven browser harnesses on 200 difficult, long-horizon web tasks using the same GPT-6.1 Terra medium model, task set, and judge, isolating harness design as a major variable in agent performance. See the benchmark repository at https://github.com/browser-use/benchmark.

// ANALYSIS

The hot take: browser agents are complete systems, not interchangeable model wrappers.

–Fixed models and judges make score differences meaningful evidence about orchestration quality.
–Observation formats, tool design, action loops, retries, and context management can determine whether long tasks survive.
–Long-horizon evaluation is more revealing than polished browser demos or short navigation tests.
–Developers should benchmark the full stack—including latency, token usage, recovery, and browser reliability—not models alone.
