UI-TARS is an end-to-end GUI agent model based on VLM architecture. It solely perceives screenshots as input and performs human-like interactions (e.g., keyboard and mouse operations), achieving state-of-the-art performance on 10+ GUI benchmarks.
UI-TARS is an open-source model, and provides different versions of size. You can deploy it on your own server, and it will dramatically improve the performance and data privacy.

## 能否选用 `gpt-4o` 以外的其他模型？
-可以。你可以[自定义模型和服务商](./model-provider)。
+当然可以。你可以按需[选择 AI 模型](./choose-a-model)。
-## 关于 token 成本
-
-图像分辨率和元素数量（即 Midscene 创建的 UI 上下文大小）会显著影响 token 消耗。
-
-以下是使用 gpt-4o-08-06 模型且未启用 prompting caching 的典型数据：

+## 会有哪些信息发送到 AI 模型？
这些信息:
1. 从 DOM 提取的关键信息，如文字内容、class name、tag name、坐标
2. 界面截图
-## 脚本运行偏慢？
+如果你担心数据隐私问题，请参阅 [数据隐私](./data-privacy)。
-由于 Midscene.js 每次进行规划（Planning）和查询（Query）时都会调用 AI，其运行耗时可能比传统 Playwright 用例增加 3 到 10 倍，比如从 5 秒变成 20秒。目前，这一点仍无法避免。但随着大型语言模型（LLM）的进步，未来性能可能会有所改善。
+## 脚本运行偏慢？
-尽管运行时间较长，Midscene 在实际应用中依然表现出色。它独特的开发体验会让代码库易于维护。我们相信，集成了 Midscene 的自动化脚本能够显著提升项目迭代效率，覆盖更多场景，提高整体生产力。
+在 Midscene.js 中使用通用大模型时，由于每次进行规划（Planning）和查询（Query）时都会调用 AI，其运行耗时可能比传统 Playwright 用例增加 3 到 10 倍，比如从 5 秒变成 20秒。为了让结果更可靠，token 和时间成本是不可避免的。
-简而言之，虽然偏慢，但这些投入一定都是值得的。
+有两种方法可以提高运行效率：
+1. 使用专用的模型，比如 UI-TARS。这是推荐的做法。更多详情请参阅 [选择 AI 模型](./choose-a-model)。
+2. 使用缓存来减少 token 消耗。更多详情请参阅 [缓存](./caching)。
