## AI 摘要

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%。

## 正文

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.
