## Antigravity Support
Sub2API supports [Antigravity](https://antigravity.so/) accounts. After authorization, dedicated endpoints are available for Claude and Gemini models.
### Dedicated Endpoints
| Endpoint | Model |
|----------|-------|
| `/antigravity/v1/messages` | Claude models |
| `/antigravity/v1beta/` | Gemini models |
### Claude Code Configuration
```bash
export ANTHROPIC_BASE_URL="http://localhost:8080/antigravity"
export ANTHROPIC_AUTH_TOKEN="sk-xxx"
```
### Hybrid Scheduling Mode
Antigravity accounts support optional **hybrid scheduling**. When enabled, the general endpoints `/v1/messages` and `/v1beta/` will also route requests to Antigravity accounts.
> **⚠️ Warning**: Anthropic Claude and Antigravity Claude **cannot be mixed within the same conversation context**. Use groups to isolate them properly.

## Antigravity 使用说明
Sub2API 支持 [Antigravity](https://antigravity.so/) 账户，授权后可通过专用端点访问 Claude 和 Gemini 模型。
### 专用端点
| 端点 | 模型 |
|------|------|
| `/antigravity/v1/messages` | Claude 模型 |
| `/antigravity/v1beta/` | Gemini 模型 |
### Claude Code 配置示例
```bash
export ANTHROPIC_BASE_URL="http://localhost:8080/antigravity"
export ANTHROPIC_AUTH_TOKEN="sk-xxx"
```
### 混合调度模式
Antigravity 账户支持可选的**混合调度**功能。开启后，通用端点 `/v1/messages` 和 `/v1beta/` 也会调度该账户。
> **⚠️ 注意**：Anthropic Claude 和 Antigravity Claude **不能在同一上下文中混合使用**，请通过分组功能做好隔离。
