백그라운드 실행

심층 연구, 복잡한 추론 또는 다단계 에이전트 실행과 같은 장기 실행 작업의 경우 연결 시간 제한으로 인해 표준 HTTP 요청이 중단될 수 있습니다 (일반적으로 60초 후에 닫힘). Interactions API는 이러한 작업을 비동기식으로 실행하는 백그라운드 실행을 제공합니다.

상호작용이 서버에서 작업을 완료할 때까지 실행되도록 하려면 상호작용을 만들 때 "background": true를 설정합니다. API는 즉시 상호작용 ID를 반환하며, 클라이언트 애플리케이션은 이 ID를 사용하여 상태를 폴링하거나, 진행 상황을 스트리밍하거나, 연결이 끊긴 스트림에 다시 연결할 수 있습니다.

백그라운드 실행은 표준 Gemini 모델 (gemini-4-argon, gemini-3.8-flash 등) 및 관리형 에이전트 (antigravity-preview-09-2026 등)에서 지원됩니다.

백그라운드 상호작용 만들기

백그라운드 상호작용을 시작하려면 리소스를 만들 때 background 매개변수를 true로 설정합니다.

Python

from google import genai

client = genai.Client()

interaction = client.interactions.create(
    model="gemini-3.8-flash",
    input="Write a guide on space exploration.",
    background=True,
)
print(f"Created background interaction ID: {interaction.id}")

JavaScript

import { GoogleGenAI } from "@google/genai";

const client = new GoogleGenAI({});

const interaction = await client.interactions.create({
    model: "gemini-3.8-flash",
    input: "Write a guide on space exploration.",
    background: true,
});
console.log(`Created background interaction ID: ${interaction.id}`);

Interaction interaction =
    client.interactions.create(CreateInteractionRequestBody.of(params)).interaction().get();
System.out.println("Created background interaction ID: " + interaction.id().orElse(""));

백그라운드 실행 작동 방식

백그라운드 상호작용을 만들면 작업이 서버에서 비동기식으로 실행됩니다. 상호작용은 다양한 실행 상태를 거칩니다.

  • in_progress: 서버가 상호작용을 적극적으로 실행하고 있습니다 (예: 코드 실행 또는 연구).
  • requires_action: 상호작용이 일시중지되었으며 클라이언트 입력 (예: 도구 실행 확인 또는 질문 답변)을 기다리고 있습니다.
  • completed: 상호작용이 성공적으로 완료되었으며 출력을 사용할 수 있습니다.
  • failed: 실행 중에 오류가 발생했습니다 (예: 도구 실패 또는 비율 제한).
  • cancelled: 클라이언트 요청으로 인해 실행이 중지되었습니다.

사용 사례

다음과 같은 경우 백그라운드 실행을 사용합니다.

  • 에이전트 실행: 코드 실행, 웹브라우징 또는 하위 에이전트 오케스트레이션이 필요한 작업 (antigravity-preview-09-2026 등)

  • 심층 연구: 몇 분이 걸리는 deep-research-preview-04-2026 또는 deep-research-max-preview-04-2026을 사용하여 실행합니다.

  • 긴 추론: 확장된 모델 사고 단계가 표준 HTTP 연결 한도를 초과하는 작업

  • 긴 디코딩 (Gemini 4): 65,536 토큰을 초과하는 확장된 완성을 생성하는 작업 gemini-4-argon에서는 긴 디코딩을 사용하여 max_output_tokens를 최대 1,048,576 토큰으로 설정할 수 있습니다.

백그라운드 실행을 위한 데이터 보관

background=True가 설정되면 서버는 상호작용을 프로젝트의 스토리지에 저장하므로 결과를 폴링하거나 스트리밍할 수 있습니다. store 매개변수를 설정하여 상호작용이 저장되는 기간을 구성할 수 있습니다.

  • store=True (기본값): 프로젝트의 영구 스토리지에 7일 동안 저장됩니다.
  • store=False: GET 요청을 사용하여 결과를 검색할 수 있도록 24시간 (TTL) 동안 프로젝트에 저장됩니다.

결과 검색

폴링 또는 스트리밍 을 사용하여 백그라운드 상호작용 결과를 가져옵니다.

폴링 패턴 (차단되지 않음)

폴링은 종료 상태에 도달할 때까지 차단되지 않는 GET 요청을 사용하여 상호작용 상태를 주기적으로 확인합니다.

Python

from google import genai

client = genai.Client()

interaction = client.interactions.get(id="YOUR_INTERACTION_ID")

while interaction.status == "in_progress":
    time.sleep(5)

스트리밍 패턴

네트워크 중단으로 인해 스트림 연결이 끊어지면 스트리밍이 마지막으로 수신된 이벤트부터 다시 시작될 수 있습니다. 각 델타에는 페이로드에 고유한 event_id가 포함되어 있습니다. 이 ID를 last_event_id로 전달하면 해당 이벤트부터 스트림이 다시 시작됩니다.

멀티턴 대화

후속 상호작용은 다음 제약 조건에 따라 previous_interaction_id를 사용하여 백그라운드 대화에 연결할 수 있습니다.

  1. 활성 실행이 차단됨: 후속 상호작용을 in_progress 상태의 상호작용에 연결하면 400 Bad Request 오류가 반환됩니다. 상호작용이 completed 상태에 도달할 때까지 기다린 후 다음 상호작용을 시작합니다.
  2. 관리형 에이전트의 환경 매개변수: 관리형 에이전트 (antigravity-preview-09-2026 등)의 상호작용을 연결할 때 요청에 previous_interaction_id와 environment가 모두 포함되어야 합니다.

취소 및 삭제

취소 및 삭제 요청을 사용하여 실행 중인 실행을 제어하고 스토리지를 관리합니다.

  • 취소 (POST /interactions/{id}/cancel): 실행 중인 작업을 중지합니다. 상태가 cancelled로 전환됩니다. 서버에서 정리 작업을 수행하면 GET 요청에서 상태가 업데이트되기 전에 약간의 지연이 발생할 수 있습니다.

  • 삭제 (DELETE /interactions/{id}): 서버에서 상호작용 레코드를 삭제합니다. 후속 GET 요청은 404 Not Found 오류를 반환합니다.

Python

from google import genai

client = genai.Client()

# Cancel a running interaction
client.interactions.cancel(id="YOUR_INTERACTION_ID")

# Delete the interaction record entirely
client.interactions.delete(id="YOUR_INTERACTION_ID")

JavaScript

import { GoogleGenAI } from "@google/genai";

// Cancel a running interaction
await client.interactions.cancel("YOUR_INTERACTION_ID");

// Delete the interaction record entirely
