环境是托管式 Linux 沙盒,可为智能体提供一个隔离的位置来执行代码和保留文件。它们与互动上下文分离,因此您可以在多个互动中重复使用同一环境,也可以随时重新开始。
以下示例演示了如何使用新的远程环境创建互动并检索其 ID:
Python
from google import genai
client = genai.Client()
interaction = client.interactions.create(
agent="antigravity-preview-05-2026",
input="Install pandas and matplotlib, verify the imports, and print the versions.",
environment="remote",
)
print(f"Environment ID: {interaction.environment_id}")
JavaScript
import { GoogleGenAI } from "@google/genai";
const client = new GoogleGenAI({});
const interaction = await client.interactions.create({
agent: "antigravity-preview-05-2026",
input: "Install pandas and matplotlib, verify the imports, and print the versions.",
environment: "remote",
});
console.log(`Environment ID: ${interaction.environment_id}`);
REST
curl -X POST "https://generativelanguage.googleapis.com/v1beta/interactions" \
-H "Content-Type: application/json" \
-H "x-goog-api-key: $GEMINI_API_KEY" \
-H "Api-Revision: 2026-05-20" \
-d '{
"agent": "antigravity-preview-05-2026",
"input": "Install pandas and matplotlib, verify the imports, and print the versions.",
"environment": "remote"
}'
environment 参数
environment 参数接受三种形式:
| 姿势 | 示例 | 适用情形 |
|---|---|---|
"remote" |
environment="remote" |
预配新的沙盒。 |
| 环境 ID | environment="env_abc123" |
重复使用包含所有文件和软件包的现有沙盒。 |
| 配置对象 | environment={...} |
预配包含来源、网络规则或两者的新沙盒。 |
以下示例演示了使用 environment 参数的三种方式。
Python
from google import genai
client = genai.Client()

配置环境
设置环境的一种方法是告知智能体您需要安装的内容。它会处理依赖项解析和问题排查。环境准备就绪后,保存 environment_id 并重复使用。
Python
from google import genai
client = genai.Client()
interaction = client.interactions.create(
agent="antigravity-preview-05-2026",
input="Install pandas, matplotlib, and seaborn. Verify all imports work and print the installed versions.",
environment="remote",
)
# Reuse the configured environment
interaction_2 = client.interactions.create(
agent="antigravity-preview-05-2026",
input="Clone https://github.com/octocat/Spoon-Knife into /workspace/tools. Run the test suite and fix any missing dependencies.",
environment=interaction.environment_id,
previous_interaction_id=interaction.id,
)
# Reuse the configured environment
interaction_3 = client.interactions.create(
agent="antigravity-preview-05-2026",
input="Using the tools in /workspace/tools, list the files.",
environment=interaction.environment_id,
previous_interaction_id=interaction_2.id,
)
print(interaction.output_text)
JavaScript
import { GoogleGenAI } from "@google/genai";
const client = new GoogleGenAI({});
const interaction = await client.interactions.create({

从来源装载
如果您确切知道智能体需要哪些文件,请在一次调用中装载这些文件,而不是进行迭代。environment 配置对象接受包含三种类型的 sources 数组:
| 来源类型 | type 值 |
说明 | 限制 |
|---|---|---|---|
| Git 代码库 | repository |
将代码库从网址克隆到 target 处的沙盒中。 |
500 MB |
| Cloud Storage | gcs |
将文件或目录从 Cloud Storage 复制到 target 处的沙盒中。 |
2 GB |
| 内嵌内容 | inline |
将原始文本内容写入 target 处的沙盒中的文件。 |
每个文件 1 MB,总共 2 MB |
Python
from google import genai
client = genai.Client()

您可以结合使用这两种方法:以声明方式装载已知来源,然后通过后续互动进行迭代以安装软件包或运行设置脚本。添加自定义来源时,您无法将根目录 (/) 设置为目标,必须始终指定子目录。
私有来源
您还可以通过在网络配置中添加凭据,从私有 GitHub 代码库或私有 Cloud Storage 存储分区下载内容:
对于私有 Git 代码库,请使用Basic身份验证和您的
GitHub 个人访问令牌
(PAT)。
使用 x-oauth-basic 作为用户名对令牌进行编码:
echo -n "x-oauth-basic:ghp_YourPATHere" | base64
Python
interaction = client.interactions.create(
agent="antigravity-preview-05-2026",

预装软件
沙盒在 Ubuntu 上运行,并预装了运行时和常用软件包。智能体可以在运行时使用 pip
install 或 npm install 安装其他软件包。当您重复使用同一 environment_id 时,在互动期间安装的软件包会保留。
| 类别 | 预装软件包 |
|---|---|
| UNIX 工具 | curl、wget、git、rsync、unzip、ripgrep、fd-find、gawk、bc、tree、which、lsof、htop、jq、iproute2、procps、gcloud CLI |
| Python 3.12 | numpy、pandas、requests、google-genai、beautifulsoup4、pyyaml、ast-grep-cli |
| Node.js 22 | create-next-app、create-vite、typescript |
网络配置
默认情况下,环境具有不受限制的出站网络访问权限。使用 network 字段将出站流量限制为特定网域。每条规则都指定一个 domain 和一个可选的 transform 对象,以将标头注入到匹配的请求中。这些标头对于每次互动可以是唯一的,并且您可以为同一环境更新这些标头。
| 字段 | 类型 | 说明 |
|---|---|---|
domain |
string |
要匹配的网域。使用确切的主机名或 * 来指定所有网域。 |
transform |
object |
包含扁平键值对的对象,这些键值对表示要注入到匹配请求中的标头,例如 {"Authorization": "Bearer ..."}。 |
Python
from google import genai
client = genai.Client()

{"domain": "pypi.org"},
{"domain": "*"}

}
}
}'
设置许可名单后,系统仅允许向明确列出的网域发出请求。您可以使用通配符来匹配子网域(例如 {"domain":
"*.example.com"}),但请注意,这不会匹配根域名
example.com,您必须单独添加该域名。如需允许所有其他流量(例如在不注入标头的情况下路由未列出的网域),请添加 {"domain": "*"} 作为全能条目。
凭据
您可以通过添加标头转换来添加凭据,供智能体使用。凭据由出站代理注入到相应的 HTTP 标头中,它们绝不会作为环境变量或文件在沙盒内公开。

环境生命周期
环境遵循以下生命周期:
| 状态 | 行为 |
|---|---|
| 已创建 | 当互动指定 environment: "remote" 或配置对象时,系统会预配环境。 |
| 有效 | 在互动进行期间运行。 |
| 空闲 | 闲置 15 分钟后,系统会自动创建快照并停止环境。 |
| 离线 | 自上次使用以来保留 7 天。可以通过传递其 ID 来恢复。 |
| 已删除 | 从系统中移除。 |
从环境下载文件
智能体在执行期间会在沙盒内创建文件。您可以使用 Files API 将完整环境快照下载为 tar 文件:
Python
import os
import requests

价格和资源
每个环境都以固定的资源分配运行:
| 资源 | 值 |
|---|---|
| CPU | 4 核 |
| 内存 | 16 GB |
在预览版期间,环境计算(CPU、内存、沙盒执行)不收费 。如需了解 智能体令牌费用,请参阅价格。
限制
- 预览版状态 :环境和托管式智能体处于预览版阶段。功能和架构可能会发生变化。
- 内嵌来源大小 :内嵌来源限制为每个文件 1 MB,所有文件总共 2 MB。
- 来源大小:Git 代码库限制为 500 MB,Cloud Storage 代码库限制为 2 GB。
- 环境启动 :预配新环境最多需要约 5 秒。大型来源代码库可能会增加此时间。
- 文件支持 :智能体目前只能读取文本和图片文件。尚不支持二进制文件。
