-Claude 由 Anthropic 提供，支持文本对话与图像理解，主流 Sonnet / Opus 模型均原生支持视觉，无需额外指定 Vision 模型。
+Claude is provided by Anthropic and supports both text chat and image understanding. The mainstream Sonnet / Opus models natively support vision, so no separate Vision model needs to be specified.
 
 <Tip>
-  通过 Web 控制台的「模型管理」页面可一站式配置以下全部能力，无需手动改配置文件。
+  All capabilities below can be configured in one place via the "Model Management" page in the Web Console, with no need to manually edit the configuration file.
