Leo 的 AI 模型之間的差異是什麼？ 追蹤
大型語言模型 (LLMs) 是訓練來生成類似人類回應的先進 AI 系統。 Brave 的 AI 助手 Leo 為用戶提供選項，以選擇適當的模型和模型配置滿足他們的隱私和功能需求。 These LLMs include the latest Qwen, Meta's Llama, and Anthropic's Claude Haiku and Claude Sonnet models, all of which Brave hosts through our own secure infrastructure. 雖然這些模型具有不同的功能，但 Brave 確保無論使用哪種模型和提供方式，用戶隱私都能得到保障。
LLMs 說明
Larger models like Qwen and Llama have more parameters and complexity, allowing them to handle more complex tasks but also requiring more computing power to run efficiently. Models trained on diverse data like Claude Sonnet have broad knowledge, while specialized models like Claude Haiku have domain expertise like coding or legal analysis. 一些 LLM 在文本生成方面表現優異，而其他則更擅長於問答或數據分析任務。 速度將取決於模型大小、運行模型的基礎設施的性能、用於優化的技術、處理的內容數量以及請求的任務的複雜性。
Importantly, all models in Brave Leo are managed and operated exclusively by Brave in secure environments, with no data sharing between Brave and the original model creators. For example, your use of Llama in Brave Leo is totally independent from the model creator, Meta.
Brave Leo 提供選項，使您能選擇適合您需求的模型。 You can use the Brave-hosted Automatic mode, manually select models from the list provided, or, for advanced users, connect Leo to your own model (See BYOM).
Privacy Protections
Models will change from time-to-time, but Brave's privacy protections will protect you no matter what model you are using:
- 您的對話在生成回應後不會被 Brave 儲存或記錄。 No personal data such as your IP address or conversation transcripts are retained. 並且您的對話不會用於模型訓練用途。
- 對話數據在聊天會話結束後立即從 Brave 的伺服器中丟棄。
- Your chat history exists only on your device in your local storage. Chats can be removed from your device in Settings by selection the option to “Clear Leo data”.
- Chats can be temporary, meaning they aren’t kept in your local storage, and chat history can be disabled entirely so conversations don’t exist on your device or anywhere else after you close them.
選擇 模型
The Leo panel includes a 3-dot icon in the header where you can change the Settings. You will see options for Language Models which you can select manually or choose to continue with the default `Automatic mode`.
You can also open advanced settings which will take you to brave://settings/leo-ai where you can select which model you want to use by default every time you use Leo.

無論您選擇哪個模型，Brave 都無法將您的訂閱信息與您實際使用模型的情況連接起來，從而為您的對話提供了額外的隱私保護。 您用來創建賬戶的電子郵件無法與您日常使用的 Leo 聯繫起來，使這成為一個獨特的私人體驗。
Brave 對用戶隱私的承諾延伸到其 LLM 產品，提供安全透明的體驗。 With all models hosted through Brave's secure infrastructure, Brave ensures user data remains private and protected. 用戶可以探索不同 LLMs 的各種功能，同時保護他們的個人信息。
Note: Updated June 30, 2025 - Brave Leo now hosts all AI models, including Claude models, through our own secure infrastructure. Previously, some models were served through external providers, but we have updated our hosting arrangement to ensure all user interactions remain within Brave's privacy-preserving environment.
