本版说明Release notes
优化了部分功能
Before you start: bring a model
Bi does not ship a model. Point it at a cloud provider, or at a local Ollama / LM Studio instance. Model keys are stored only in the local .bi directory.

Apple Silicon 与多数 Windows 电脑选 ARM64；Intel 设备选 x64。macOS 推荐下载安装盘（.dmg），双击挂载后拖入「应用程序」；绿色版解压即用。
Pick ARM64 for Apple Silicon and most Windows PCs; x64 for Intel. On macOS we recommend the installer (.dmg): mount it and drag Bi into Applications. The portable build just needs unzipping.

- 1
下载
选择与你的系统匹配的压缩包或安装盘。
- 2
解压 / 安装
macOS 下载 .dmg 双击挂载，把 Bi 拖入「应用程序」；绿色版解压后得到可执行文件与 ocr/ 目录，两者保持同级。
- 3
运行
macOS 直接打开 Bi；绿色版在 macOS 与 Linux 需先赋予执行权限。
- 4
打开并配置模型
启动后进入工作台；在「设置」中配置模型提供商（云端 API 或本机 Ollama / LM Studio）后即可使用。
Up and running in four steps
- 1
Download
Choose the archive or installer that matches your system.
- 2
Unzip / install
macOS: mount the .dmg and drag Bi into Applications. Portable build: unzip — you get the executable plus an ocr/ directory; keep them together.
- 3
Run
macOS: just open Bi. Portable builds on macOS and Linux need execute permission first.
- 4
Open and configure a model
The workbench opens on launch. Add a model provider in Settings — a cloud API or a local Ollama / LM Studio instance — and you are ready.
macOS 与 Linux 的运行权限（绿色版）
安装盘（.dmg）无需以下步骤，拖入应用程序后直接双击运行。绿色版（.zip）需先解压，再在终端进入解压目录。macOS 与 Linux 的可执行文件默认不含执行权限，直接运行将提示「权限被拒绝」；按系统执行下列命令（将 x64 替换为所下载的架构，Apple Silicon 使用 ARM64）。
macOS
macOS 绿色版未签名；若被 Gatekeeper 拦截，需先添加执行权限，再移除隔离标记：
chmod +x bi-darwin-arm64
xattr -d com.apple.quarantine bi-darwin-arm64
./bi-darwin-arm64Linux
Linux 只需要加执行权限：
chmod +x bi-linux-amd64
./bi-linux-amd64Run permissions on macOS and Linux (portable build)
The installer (.dmg) needs none of this — drag it into Applications and double-click. For the portable build (.zip), unzip first and open a terminal in the unzipped folder. macOS and Linux executables have no execute bit by default, so a direct run can fail with “permission denied”. Run the commands for your system (swap x64 for the architecture you downloaded; Apple Silicon uses ARM64).
macOS
The macOS portable build is unsigned; if Gatekeeper blocks it, add execute permission and remove the quarantine flag:
chmod +x bi-darwin-arm64
xattr -d com.apple.quarantine bi-darwin-arm64
./bi-darwin-arm64Linux
Linux only needs execute permission:
chmod +x bi-linux-amd64
./bi-linux-amd64常见问题
需要安装吗？
Bi 本体无需安装，解压后即可运行。首次使用前需配置一个模型服务：云端 API，或本机的 Ollama / LM Studio。
数据是否上传？
不会上传至 Bi 的服务器——Bi 不设服务器。会话、文件与数据库保存在本机 .bi 目录；若配置远程模型提供商，对话内容将发送至指定的模型端点。macOS 的 Bi.app 将 .bi 与工作区置于应用所在目录；安装在「应用程序」等只读位置时，回退至 ~/Library/Application Support/Bi。
macOS 与 Linux 是否提供系统托盘？
macOS 提供菜单栏图标，可打开工作台、工作区、配置目录与日志，并支持重启与退出。Linux 以服务模式运行，界面通过浏览器访问。
与云端 Agent 的区别？
工作区、文件与会话保留在本机，模型可自行选择。云端服务通常将工作区托管于其服务器；Bi 将控制权保留在本地。
为什么强调 Token 效率？
上下文长度、文件读取与工具调用直接影响响应速度、成本与稳定性。降低消耗带来的不仅是成本下降，也包括更短的等待时间。
FAQ
Do I need to install anything?
Bi itself needs no installation: unzip and run. You do need a model provider first — a cloud API or a local Ollama / LM Studio instance.
Is my data uploaded anywhere?
Not to a Bi server — Bi has no server. Sessions, files and the database stay in the local .bi directory; if you configure a remote model provider, conversation content is sent to the model endpoint you chose. On macOS, Bi.app keeps .bi and the workspace next to Bi.app itself (or falls back to ~/Library/Application Support/Bi when installed in a read-only location such as Applications).
Is there a system tray on macOS and Linux?
macOS has a menu bar icon (tray) — open the workbench, workspace, config folder and logs, plus restart/quit. Linux runs in service mode with the UI in your browser.
How is Bi different from a cloud agent?
Your workspace, files and sessions stay on your machine, and you choose the model. Cloud services usually keep the workspace on their servers; Bi keeps control with you.
Why the emphasis on token efficiency?
Context, reads and tool calls directly affect speed, cost and reliability. What you save is not only money — it is time to a usable result.
