BrowserBC：用蒸馏技能让小型模型高效运行Web Agent

BrowserBC, a new open-source project from the ViDA team, explores a more efficient way to run web agents.

Instead of using a frontier model for every step of an agent workflow, BrowserBC records a human web flow once with a stronger model, distills it into a reusable skill, and then lets a smaller, cheaper model handle execution.

The reported results are notable: on WebArena-Hard, tool calls drop by 27%, while success increases from 60% to 81%.

A very good open source project at the right time.
