ViDA 团队开源的 BrowserBC 项目,探索更高效的 web agent 运行方式:先用强模型录制一次人类浏览器操作流程,将其蒸馏为可复用技能,再交给更小更便宜的模型执行。一次录制即可泛化技能。在 WebArena-Hard 上,tool calls 降低 27%,成功率从 60% 升至 81%。
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.
