Panduan ini membantu Anda bermigrasi dari generateContent API ke Interactions API.
Interactions API adalah cara paling sederhana dan terbaik untuk membangun dengan model dan agen Gemini. Meskipun generateContent tetap didukung sepenuhnya, sebaiknya gunakan Interactions API untuk semua pengembangan baru.
Mengapa harus bermigrasi?
Interactions API adalah cara termudah dan terbaik kami untuk membangun dengan model dan agen Gemini:
- Pengelolaan histori sisi server: Alur multi-turn yang disederhanakan melalui
previous_interaction_id. Server mengaktifkan status secara default (store=true), tetapi Anda dapat memilih perilaku tanpa status dengan menyetelstore=false. - Langkah-langkah eksekusi yang dapat diamati: Langkah-langkah yang diketik memudahkan proses men-debug alur yang kompleks dan merender UI untuk peristiwa perantara (seperti pemikiran atau widget penelusuran).
- Penggunaan alat dan alur kerja agentic: Dukungan native untuk penggunaan alat multi-langkah, orkestrasi, dan alur penalaran yang kompleks melalui langkah-langkah eksekusi yang diketik.
- Tugas latar belakang dan berjalan lama: Mendukung operasi yang memakan waktu seperti Deep Think dan Deep Research ke proses latar belakang menggunakan
background=true.
Input/output dasar
Bagian ini menunjukkan cara memigrasikan permintaan pembuatan teks sederhana.
Sebelum (generateContent)
generateContent API tidak memiliki status dan menampilkan respons secara langsung. Struktur respons membungkus output dalam daftar candidates, yang masing-masing berisi content dengan daftar parts yang akan diuraikan.
Python
from google import genai
client = genai.Client()
response = client.models.generate_content(
model="gemini-2.5-flash-lite", contents="Tell me a joke."
)
print(response.text)
JavaScript
import { GoogleGenAI } from '@google/genai';
const ai = new GoogleGenAI({});
const response = await ai.models.generateContent({
model: "gemini-2.5-flash-lite",
contents: "Tell me a joke.",
});
console.log(response.text);

import com.google.genai.gaos.models.interactions.Model;

Client client = new Client();
CreateModelInteraction params =
CreateModelInteraction.builder()
.model(Model.of("gemini-3.8-flash"))
.input(InteractionsInput.of("Explain how AI works in a few words"))
.build();
Interaction interaction =
client.interactions.create(CreateInteractionRequestBody.of(params)).interaction().get();
System.out.println(interaction.outputText().orElse(""));

Interactions API menampilkan resource interaksi tersimpan dengan linimasa steps. Meskipun Anda dapat memeriksa array steps secara manual untuk menemukan peristiwa
perantara, SDK GenAI Google menyediakan properti praktis
langsung pada objek Interaction yang ditampilkan untuk mengakses output akhir.
Properti kemudahan yang paling umum adalah .output_text (String), yang
secara otomatis mengekstrak dan menggabungkan blok TextContent berurutan di
akhir respons model. Meskipun berfungsi sempurna untuk respons sederhana,
respons ini tidak menyertakan blok teks sebelumnya yang dipisahkan oleh konten non-teks (seperti
pemikiran, gambar, audio, atau panggilan alat). Untuk respons multimodal yang kompleks atau berselang-seling, Anda harus melakukan iterasi secara manual pada steps.
Python
from google import genai
client = genai.Client()
interaction = client.interactions.create(

)
print(interaction.output_text)

Percakapan multi-giliran
Interactions API menyimpan interaksi secara default, sehingga memungkinkan pengelolaan status sisi server untuk percakapan multi-giliran.
Sebelum (generateContent)
Di generateContent, Anda harus mengelola histori percakapan secara manual menggunakan array contents atau helper chat sisi klien.
Python
Menggunakan bantuan chat (direkomendasikan)
from google import genai
client = genai.Client()
chat = client.chats.create(model="gemini-2.5-flash-lite")
response1 = chat.send_message("Hi, my name is Phil.")
print(response1.text)
response2 = chat.send_message("What is my name?")
print(response2.text)
Mengelola histori secara manual
from google import genai
from google.genai import types
client = genai.Client()
response = client.models.generate_content(
model="gemini-2.5-flash-lite",
contents=[
types.Content(
role="user", parts=[types.Part.from_text(text="Hi, my name is Phil.")]
),
types.Content(
role="model",
parts=[types.Part.from_text(text="Hi Phil, how can I help you?")],
),
types.Content(
role="user", parts=[types.Part.from_text(text="What is my name?")]
),
],
)
print(response.text)
JavaScript
Menggunakan bantuan chat (direkomendasikan)
import { GoogleGenAI } from '@google/genai';
const client = new GoogleGenAI({});
const chat = client.chats.create({ model: 'gemini-2.5-flash-lite' });
let response = await chat.sendMessage({ message: 'Hi, my name is Phil.' });
console.log(response.text);
response = await chat.sendMessage({ message: 'What is my name?' });
console.log(response.text);

Setelah (Interactions API)
Interactions API mengelola status di server. Anda melanjutkan percakapan dengan merujuk ke previous_interaction_id.
Python
from google import genai
client = genai.Client()
interaction1 = client.interactions.create(
model="gemini-3.8-flash", input="Hi, my name is Phil."
)
print("Response 1:", interaction1.output_text)
interaction2 = client.interactions.create(

previous_interaction_id=interaction1.id,
input="What is my name?",
)
print("Response 2:", interaction2.output_text)
JavaScript
import { GoogleGenAI } from '@google/genai';
const client = new GoogleGenAI({});
let interaction = await client.interactions.create({
model: 'gemini-3.8-flash',

Input multimodal
Kedua API ini mendukung input multimodal (teks, gambar, video, dll.).
Sebelum (generateContent)
Di generateContent, Anda meneruskan daftar parts dalam array contents. Respons menampilkan output dalam parts kandidat pertama.
Python
from google import genai
from google.genai import types
client = genai.Client()
with open("sample.jpg", "rb") as f:
image_bytes = f.read()
response = client.models.generate_content(

Setelah (Interactions API)
Di Interactions API, Anda meneruskan array ke kolom input. Anda mengambil konten output dengan menemukan langkah model_output di linimasa.
Python

Output terstruktur
Untuk membuat model menampilkan JSON yang sesuai dengan skema tertentu, konfigurasikan format respons.
Sebelum (generateContent)
Di generateContent, Anda mengonfigurasi format output menggunakan kolom response_mime_type dan response_schema yang berada di dalam objek config (atau generationConfig).
Python
from google import genai
from google.genai import types
from pydantic import BaseModel
client = genai.Client()
class Recipe(BaseModel):
recipe_name: str
ingredients: list[str]
response = client.models.generate_content(

Pembuatan multimodal
Saat membuat konten dalam modalitas selain teks (seperti gambar atau audio), perbedaan utamanya adalah cara respons menyusun media yang dibuat.
Sebelum (generateContent)
Di generateContent, respons menampilkan media yang dihasilkan secara langsung di parts kandidat, biasanya sebagai data base64 di inlineData.
# Response structure concept
{
"candidates": [
{
"content": {
"parts": [
{
"text": "Here is your generated image:"
},
{
"inlineData": {
"mimeType": "image/jpeg",
"data": "...base64..."
}
}
]
}
}
]
}
Setelah (Interactions API)
Di Interactions API, media yang dihasilkan muncul sebagai item berbeda dalam array content dari langkah model_output dalam linimasa, sehingga mempertahankan alur kronologis interaksi.
# Response structure concept
{
"id": "int_123",
"steps": [
{
"type": "model_output",
"status": "done",
"content": [
{
"type": "text",
"text": "Here is your generated image:"
},
{
"type": "image",
"mime_type": "image/jpeg",
"data": "...base64..." // Or a reference URL in future
}
]
}
]
}
Hal ini membuat penguraian respons konsisten dengan cara penanganan input dan output teks—semuanya adalah langkah dalam linimasa.
Alat sisi server
Gemini mendukung alat bawaan sisi server seperti perujukan Google Penelusuran. Perbedaan utamanya adalah cara respons merepresentasikan eksekusi alat.
Sebelum (generateContent)
Di generateContent, alat sisi server sebagian besar tidak transparan. Anda mengaktifkan alat dan mendapatkan jawaban akhir dengan objek groundingMetadata terpisah. Yang penting, kutipan tidak inline; groundingSupports menggunakan indeks karakter untuk memetakan kembali segmen teks ke sumber web di groundingChunks.
Python
from google import genai
from google.genai import types
client = genai.Client()
response = client.models.generate_content(
model="gemini-2.5-flash-lite",
contents="Who won Euro 2024?",
config=types.GenerateContentConfig(
tools=[{"google_search": {}}]
),
)
metadata = response.candidates[0].grounding_metadata
if metadata.search_entry_point:
print(f"Search Entry Point: {metadata.search_entry_point.rendered_content}")
for support in metadata.grounding_supports:
print(f"Citation: {support.segment.text}")
JavaScript
import { GoogleGenAI } from '@google/genai';
const client = new GoogleGenAI({});
const response = await client.models.generateContent({
model: 'gemini-2.5-flash-lite',
contents: 'Who won Euro 2024?',
config: {
tools: [{ google_search: {} }]

Setelah (Interactions API)
Di Interactions API, alat sisi server memberikan transparansi linimasa penuh. API mencatat panggilan dan hasil sebagai eksekusi steps (google_search_call dan google_search_result) yang berbeda, sehingga menunjukkan secara persis data apa yang diambil model.
Selain itu, API menampilkan kutipan inline. Alih-alih memetakan indeks dari objek metadata terpisah, item teks dalam langkah model_output berisi array annotations-nya sendiri yang ditautkan langsung ke sumber.

Streaming
Perbedaan utama dalam streaming adalah bahwa Interactions API menggunakan endpoint yang sama dengan "stream": true di isi permintaan, sedangkan generateContent API memerlukan panggilan endpoint khusus (:streamGenerateContent).
Selain itu, peristiwa streaming kini menggunakan jenis khusus untuk memantau siklus proses interaksi dan melacak langkah-langkah eksekusi di sepanjang linimasa.
Sebelum (generateContentStream)
Dengan generateContent, Anda menggunakan aliran potongan respons.
Python
from google import genai
client = genai.Client()
response = client.models.generate_content_stream(
model="gemini-2.5-flash-lite", contents="Tell me a story"
)
for chunk in response:
print(chunk.text, end="")

const responseStream = await client.models.generateContentStream({

Di Interactions API, streaming menggunakan Peristiwa yang Dikirim Server (SSE) dan jenis delta khusus untuk merepresentasikan langkah-langkah eksekusi saat terjadi.

Alat streaming dan panggilan fungsi
Perilaku alat dalam aliran telah berubah secara signifikan dari generateContent untuk memberikan kontrol dan visibilitas yang lebih terperinci.

Dengan generateContent, panggilan fungsi streaming tiba lengkap dalam satu bagian. Anda tidak dapat melihat argumen yang dibuat secara real-time, sehingga handler hanya memeriksa objek functionCall yang lengkap.
