Генерация текста

API Gemini позволяет генерировать текстовый вывод из текста, изображений, видео и аудиоданных.

Вот простой пример:

Python 

# This will only work for SDK newer than 2.0.0
from google import genai

client = genai.Client()

interaction = client.interactions.create(
    model="gemini-3-flash-preview",
    input="How does AI work?"
)
print(interaction.steps[-1].content[0].text)

JavaScript 

// This will only work for SDK newer than 2.0.0
import { GoogleGenAI } from "@google/genai";

const ai = new GoogleGenAI({});

async function main() {
  const interaction = await ai.interactions.create({
    model: "gemini-3-flash-preview",
    input: "How does AI work?",
  });
  console.log(interaction.steps.at(-1).content[0].text);
}

await main();

ОТДЫХ 

# Specifies the API revision to avoid breaking changes when they become default
curl -X POST "https://generativelanguage.googleapis.com/v1beta/interactions" \
  -H "x-goog-api-key: $GEMINI_API_KEY" \

    "input": "How does AI work?"
  }'

Мышление Близнецов

В моделях Gemini функция "размышления" часто включена по умолчанию, что позволяет модели рассуждать, прежде чем ответить на запрос.

Каждая модель поддерживает различные варианты мышления, что позволяет контролировать стоимость, задержку и интеллектуальные возможности. Для получения более подробной информации см. руководство по мышлению .

Python 

# This will only work for SDK newer than 2.0.0
from google import genai

client = genai.Client()

interaction = client.interactions.create(
    model="gemini-3-flash-preview",
    input="How does AI work?",
    generation_config={
        "thinking_level": "low"
    }
)
print(interaction.steps[-1].content[0].text)

JavaScript 

// This will only work for SDK newer than 2.0.0

const ai = new GoogleGenAI({});

async function main() {
  const interaction = await ai.interactions.create({

Системные инструкции и другие настройки

Вы можете управлять поведением моделей Gemini с помощью системных инструкций. Передайте параметр system_instruction , чтобы настроить поведение модели.

Python 

# This will only work for SDK newer than 2.0.0
from google import genai

client = genai.Client()

interaction = client.interactions.create(
    model="gemini-3-flash-preview",
    system_instruction="You are a cat. Your name is Neko.",
    input="Hello there"
)

print(interaction.steps[-1].content[0].text)

JavaScript 

// This will only work for SDK newer than 2.0.0
import { GoogleGenAI } from "@google/genai";

const ai = new GoogleGenAI({});

async function main() {
  const interaction = await ai.interactions.create({
    model: "gemini-3-flash-preview",
    input: "Hello there",
    system_instruction: "You are a cat. Your name is Neko.",
  });
  console.log(interaction.steps.at(-1).content[0].text);
}

await main();

  -d '{
    "model": "gemini-3-flash-preview",
    "system_instruction": "You are a cat. Your name is Neko.",
    "input": "Hello there"
  }'

Вы также можете переопределить параметры генерации по умолчанию, такие как температура, используя параметр generation_config .

Python 

# This will only work for SDK newer than 2.0.0
from google import genai

client = genai.Client()

interaction = client.interactions.create(
    model="gemini-3-flash-preview",
    input="Explain how AI works",
    generation_config={
        "temperature": 0.1
    }
)
print(interaction.steps[-1].content[0].text)

JavaScript 

// This will only work for SDK newer than 2.0.0
import { GoogleGenAI } from "@google/genai";

const ai = new GoogleGenAI({});

async function main() {
  const interaction = await ai.interactions.create({

    input: "Explain how AI works",
    generation_config: {
      temperature: 0.1,
    },
  });
  console.log(interaction.steps.at(-1).content[0].text);

  }'

Мультимодальные входные данные

API Gemini поддерживает мультимодальный ввод, позволяя комбинировать текст с медиафайлами. Следующий пример демонстрирует передачу изображения:

Python 

# This will only work for SDK newer than 2.0.0
from google import genai

client = genai.Client()

uploaded_file = client.files.upload(file="path/to/organ.jpg")

interaction = client.interactions.create(
    model="gemini-3-flash-preview",
    input=[
        {"type": "text", "text": "Tell me about this instrument"},
        {
            "type": "image",
            "uri": uploaded_file.uri,
            "mime_type": uploaded_file.mime_type
        }
    ]
)
print(interaction.steps[-1].content[0].text)

JavaScript 

// This will only work for SDK newer than 2.0.0
import { GoogleGenAI } from "@google/genai";

const ai = new GoogleGenAI({});

async function main() {
  const uploadedFile = await ai.files.upload({
    file: "path/to/organ.jpg",
    config: { mimeType: "image/jpeg" }
  });

  const interaction = await ai.interactions.create({
    model: "gemini-3-flash-preview",
    input: [
      {type: "text", text: "Tell me about this instrument"},
      {
        type: "image",
        uri: uploadedFile.uri,
        mime_type: uploadedFile.mimeType
      }
    ],
  });
  console.log(interaction.steps.at(-1).content[0].text);
}

await main();

  }'

Альтернативные методы предоставления изображений и более сложные методы обработки изображений описаны в нашем руководстве по распознаванию изображений . API также поддерживает ввод и распознавание документов , видео и аудио .

Потоковые ответы

По умолчанию модель возвращает ответ только после завершения всего процесса генерации.

Для более плавной работы используйте потоковую обработку для обработки фрагментов ответа по мере их генерации.

Python 

# This will only work for SDK newer than 2.0.0
from google import genai

client = genai.Client()

stream = client.interactions.create(
    model="gemini-3-flash-preview",
    input="Explain how AI works",
    stream=True
)
for event in stream:
    if event.event_type == "step.delta":
        if event.delta.type == "text":
            print(event.delta.text, end="")

JavaScript 

// This will only work for SDK newer than 2.0.0
import { GoogleGenAI } from "@google/genai";

const ai = new GoogleGenAI({});

async function main() {
  const stream = await ai.interactions.create({
    model: "gemini-3-flash-preview",
    input: "Explain how AI works",
    stream: true,
  });

  for await (const event of stream) {
    if (event.event_type === "step.delta") {
      if (event.delta.type === "text") {
        process.stdout.write(event.delta.text);
      }
    }
  }
}

await main();

Многоэтапные переговоры

API взаимодействий поддерживает многоходовые диалоги, объединяя взаимодействия с помощью previous_interaction_id . Каждый ход представляет собой отдельное взаимодействие, и API автоматически управляет историей диалога.

Python 

# This will only work for SDK newer than 2.0.0
from google import genai

client = genai.Client()

interaction1 = client.interactions.create(
    model="gemini-3-flash-preview",
    input="I have 2 dogs in my house.",
)
print(interaction1.steps[-1].content[0].text)

interaction2 = client.interactions.create(
    model="gemini-3-flash-preview",
    input="How many paws are in my house?",
    previous_interaction_id=interaction1.id,
)
print(interaction2.steps[-1].content[0].text)

JavaScript 

// This will only work for SDK newer than 2.0.0
import { GoogleGenAI } from "@google/genai";

const ai = new GoogleGenAI({});

async function main() {
  const interaction1 = await ai.interactions.create({
    model: "gemini-3-flash-preview",
    input: "I have 2 dogs in my house.",
  });
  console.log("Response 1:", interaction1.steps.at(-1).content[0].text);

  const interaction2 = await ai.interactions.create({
    model: "gemini-3-flash-preview",
    input: "How many paws are in my house?",
    previous_interaction_id: interaction1.id,
  });
  console.log("Response 2:", interaction2.steps.at(-1).content[0].text);

Потоковая передача данных также может использоваться для многоходовых диалогов путем объединения previous_interaction_id с методами потоковой передачи.

Бессостоятельные беседы

По умолчанию API взаимодействий управляет состоянием диалога на стороне сервера при использовании previous_interaction_id . Однако вы также можете работать в режиме без сохранения состояния, управляя историей диалога самостоятельно на стороне клиента.

Для использования режима без сохранения состояния: 1. Установите store=false в вашем запросе, чтобы отказаться от хранения данных на стороне сервера. 2. Храните историю разговора в виде массива шагов на стороне клиента. 3. В последующих запросах передавайте накопленные шаги в поле input и добавляйте свой новый ход в качестве шага user_input .
