Google 從 Chrome 138 版本開始將 Gemini Nano 模型直接嵌入桌面客戶端。這是一種輕量級的大語言模型，在使用者裝置本地執行，所有資料處理都在端側完成，無需上傳至伺服器。瀏覽器會自動管理模型的分發、更新，並充分利用裝置的 GPU、NPU 或 CPU 進行硬體加速。
準備
軟體
支持 AI 功能的 Chrome 需要 138 版本以上。
瀏覽器相容性：
硬體
語言偵測器和翻譯器 API 適用於 Chrome 電腦版。這些 API 無法在行動裝置上運作。在 Chrome 中，只要符合下列條件，即可使用 Prompt API、Summarizer API、Writer API、Rewriter API 和 Proofreader API：
- 作業系統：Windows 10 或 11；macOS 13 以上版本 (Ventura 以上版本)； Linux；或 Chromebook Plus 裝置上的 ChromeOS (從 Platform 16389.0.0 以上版本開始)。 使用 Gemini Nano 的 API 目前不支援 Android 版、iOS 版 Chrome，以及非 Chromebook Plus 裝置上的 ChromeOS。
- 儲存空間：包含 Chrome 設定檔的磁碟區至少要有 22 GB 的可用空間。
- GPU 或 CPU：內建模型可透過 GPU 或 CPU 執行。
- GPU：VRAM 必須超過 4 GB。
- CPU：RAM 16 GB 以上，CPU 核心 4 個以上。
- 網路：無限量數據或不計量的連線，下載模型會消耗大量數據。
啟用

`Extracting WARP to generate a WireGuard
Aug 23, 2023 develop
💡 If you just want to use WARP, just install the [official client 1.1.1.1](https://1.1.1.1) directly
⚠️ Since my computer is a MacBook, this post is based on macOS, if you are using Windows or Linux, some of the steps may be different.
Preparatory steps:
Install the official client
Use wgcf to convert to a WireGuard profile
Settings WireGuard client
Other: Find endpoints in CN 🇨🇳
Install the official client
Client download: 🔗 Link
Use wgcf to convert to a WireGuard profile
Install a warp unofficial, cross-platform CLI wgcf
wgcf project:
https://github.com/ViRb3/wgcf
I’m using the Mac, so just use 🍺 Homebrew to install it.
brew install wgcf
Use cd to enter the directory where you want to store the config file (in case you can’t find it😞
Register wgcf
wgcf register
The command mentioned above will generate a wgcf-account.toml file in the current directory.
Run the following command in a terminal:
wgcf generate
The WireGuard profile will be saved under wgcf-profile.conf.
Getting the License Key in CloudFlare WARP
⚙︎ → Preferences → Account → License Key
Untitled
Untitled
Edit wgcf-account.toml directly with the new license key and run:
wgcf update
or, using an environment variable:
WGCF_LICENSE_KEY="Your License Key" wgcf update
The license will be applied, and a new private key will be created for your account.
Okay, now you have all the setup content you need to use. ✅
Settings WireGuard client
open the wgcf-profile.conf file.
[Interface]
PrivateKey = ***
Address = 172.16.0.2/32
Address = 2606:4700:110:8804:f095:3189:b06c:f68f/128
DNS = 1.1.1.1
MTU = 1280
[Peer]
PublicKey = ***
AllowedIPs = 0.0.0.0/0
AllowedIPs = ::/0
Endpoint =
engage.cloudflareclient.com:2408
I set on Shadowrocket app
Untitled
Fill the text field with the values in wgcf-profile.conf
Done! 🚀
Other: Find endpoints in CN 🇨🇳
The official domain name used at CN has been affected by DNS pollution.
engage.cloudflareclient.com:2408
To access it properly, you need to find an endpoint.
Here we use MisakaNo’s method to find the Endpoint.
macOS/Linux:
Run this command
wget -N
https://gitlab.com/Misaka-blog/warp-script/-/raw/main/files/warp-yxip/warp-yxip.sh && bash
warp-yxip.sh
Windows:
Download this file
Unzip it (7zip)
Run warp-yxip.bat
You’ll get a list and a csv document for Endpoint, just pick the one that works.
Good luck 🍀
