免费使用 Gemini 3 Pro

通过 opencode-antigravity-auth 插件，你可以在 OpenCode 里用上 Google 的 Gemini 3 Pro 模型。 插件地址 https://github.com/NoeFabris/opencode-antigravity-auth↗

# 配置方法#

## 1. 使用 Agent 帮忙安装#

最简单的方法是直接告诉 OpenCode

"Install the opencode-antigravity-auth plugin and add the Antigravity model definitions to ~/.config/opencode/opencode.json by following: https://raw.githubusercontent.com/NoeFabris/opencode-antigravity-auth/dev/README.md↗"

OpenCode 会自动帮你安装好插件并添加对应模型列表。 注意通过 Antigravity 使用的 Gemini 模型有 antigravity 的前缀，不要选错了

## 2. 手动配置#

添加插件 （ ~/.config/opencode/opencode.json ）：

json
复制
{
  "plugin": ["opencode-antigravity-auth@latest"]
}

Authenticate认证

opencode auth login

添加模型到配置文件 ~/.config/opencode/opencode.json

json
复制
