Gemini 3.8 Flash è ora disponibile. Mettiti alla prova.

Google utilizza la tecnologia AI per tradurre i contenuti nella tua lingua preferita. Le traduzioni generate dall'AI potrebbero contenere errori.

Guida introduttiva

Questa guida ti aiuta a iniziare a utilizzare l'API Gemini utilizzando l'API Interactions. Farai la tua prima chiamata API in meno di un minuto ed esplorerai la generazione di testo, la comprensione multimodale, la generazione di immagini, l'output strutturato, gli strumenti, la chiamata di funzione, gli agenti e l'esecuzione in background.

L'API Interactions è disponibile tramite gli SDK Python e JavaScript, nonché tramite REST.

1. Ottieni una chiave API

Per utilizzare l'API Gemini, devi disporre di una chiave API per autenticare le richieste, applicare limiti di sicurezza e monitorare l'utilizzo del tuo account.

Google AI Studio crea automaticamente un progetto e una chiave API per i nuovi utenti. Puoi copiarla dalla pagina Chiavi API.
Se hai bisogno di una nuova chiave, fai clic su Crea chiave API in AI Studio e segui la finestra di dialogo per aggiungere una nuova coppia chiave-progetto.

Crea una chiave API Gemini

Imposta la chiave come variabile di ambiente:

export GEMINI_API_KEY="YOUR_API_KEY"

Eseguire l'upgrade al livello a pagamento

L'upgrade al livello a pagamento aumenta i limiti di frequenza e richiede la configurazione di fatturazione Cloud.

Fai clic su Configura la fatturazione nelle pagine Chiavi API o Progetti di AI Studio.
Segui la finestra di dialogo Fatturazione Cloud per creare o collegare un account di fatturazione, aggiungere un metodo di pagamento e pagare in anticipo un minimo di 5 $ (o l'equivalente in valuta) in crediti a pagamento.
Visualizza l'utilizzo dell'API in Google AI Studio in Dashboard > Utilizzo.

Per ulteriori informazioni, consulta la pagina Fatturazione.

2. Installare l'SDK ed effettuare la prima chiamata

Installa l'SDK e genera il testo con una sola chiamata API.

Python

Installa l'SDK:

pip install -U google-genai

Inizializza il client ed effettua una richiesta:

from google import genai

client = genai.Client()

interaction = client.interactions.create(
    model="gemini-3.8-flash",
    input="Explain how AI works in a few words"
)
print(interaction.output_text)

JavaScript

Installa l'SDK:

npm install @google/genai

Inizializza il client ed effettua una richiesta:

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

const ai = new GoogleGenAI({});

const interaction = await ai.interactions.create({
  model: "gemini-3.8-flash",
  input: "Explain how AI works in a few words",
});
console.log(interaction.output_text);

Java

import com.google.genai.Client;
import com.google.genai.gaos.models.interactions.CreateModelInteraction;
import com.google.genai.gaos.models.interactions.Interaction;
import com.google.genai.gaos.models.interactions.InteractionsInput;
import com.google.genai.gaos.models.interactions.Model;
import com.google.genai.gaos.models.operations.CreateInteractionRequestBody;

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(""));

Go

package main

import (
    "context"
    "fmt"
    "log"

    "google.golang.org/genai"
    "google.golang.org/genai/interactions/models/interactions"
    "google.golang.org/genai/interactions/models/operations"
)

func main() {
    ctx := context.Background()
    client, err := genai.NewClient(ctx, nil)
    if err != nil {
        log.Fatal(err)
    }

    res, err := client.Interactions.Create(ctx, operations.CreateInteractionRequest{
        Body: operations.NewCreateInteractionRequestBody(interactions.CreateModelInteraction{
            Model: interactions.Model("gemini-3.8-flash"),
            Input: interactions.NewInteractionsInput("Explain how AI works in a few words."),
        }),
    })
    if err != nil {
        log.Fatal(err)
    }

    if res.Interaction.OutputText != nil {
        fmt.Println(*res.Interaction.OutputText)
    }
}

REST

curl -X POST "https://generativelanguage.googleapis.com/v1beta/interactions" \
  -H "x-goog-api-key: $GEMINI_API_KEY" \
  -H 'Content-Type: application/json' \
  -d '{
    "model": "gemini-3.8-flash",
    "input": "Explain how AI works in a few words"
  }'

Risposta:

{
  "id": "v1_ChdpQUFvYXI...",
  "status": "completed",
  "usage": {
    "total_tokens": 197,
    "total_input_tokens": 8,
    "total_output_tokens": 12
  },
  "created": "2026-06-09T12:01:25Z",
  "steps": [

      "content": [
        {
          "type": "text",
          "text": "AI learns patterns from data, then uses those patterns to make predictions or decisions on new data."
        }
      ]
    }
  ],
  "object": "interaction",
  "model": "gemini-3.8-flash",
}

Quando utilizzi REST, l'API restituisce la risorsa Interaction completa contenente metadati, statistiche di utilizzo e la cronologia passo passo della svolta.

Sebbene gli SDK espongano la risposta completa, forniscono anche proprietà pratiche come interaction.output_text e interaction.output_image per accedere direttamente agli output finali. Scopri di più sulla struttura della risposta nella panoramica delle interazioni o leggi la guida alla generazione di testo per informazioni dettagliate sulle istruzioni di sistema e sulla configurazione della generazione.

3. Visualizzare in streaming la risposta

Per interazioni più fluide, riproduci in streaming la risposta man mano che viene generata. Ogni evento step.delta fornisce un blocco di testo che puoi visualizzare immediatamente.

Python

from google import genai

client = genai.Client()

stream = client.interactions.create(
    model="gemini-3.8-flash",
    input="Explain how AI works",
    stream=True
)
for event in stream:
    print(event)

JavaScript

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

const ai = new GoogleGenAI({});

const stream = await ai.interactions.create({
  model: "gemini-3.8-flash",
  input: "Explain how AI works",
  stream: true,
});

for await (const event of stream) {
  console.log(event);
}

Java

import com.google.genai.Client;
import com.google.genai.gaos.models.interactions.CreateModelInteraction;
import com.google.genai.gaos.models.interactions.InteractionSSEStreamEvent;
import com.google.genai.gaos.models.interactions.InteractionsInput;
import com.google.genai.gaos.models.interactions.Model;
import com.google.genai.gaos.models.operations.CreateInteractionRequestBody;
import com.google.genai.gaos.models.operations.CreateInteractionResponse;
import com.google.genai.gaos.utils.EventStream;

Client client = new Client();

CreateModelInteraction params =
    CreateModelInteraction.builder()
        .model(Model.of("gemini-3.8-flash"))
        .input(InteractionsInput.of("Explain how AI works"))
        .stream(true)
        .build();

CreateInteractionResponse response =
    client.interactions.create(CreateInteractionRequestBody.of(params));

try (EventStream<InteractionSSEStreamEvent> stream = response.events()) {
  for (InteractionSSEStreamEvent event : stream) {
    System.out.println(event);
  }
}

Go

package main

import (
    "context"
    "fmt"
    "log"

    "google.golang.org/genai"
    "google.golang.org/genai/interactions/models/interactions"
    "google.golang.org/genai/interactions/models/operations"
)

func main() {
    ctx := context.Background()
    client, err := genai.NewClient(ctx, nil)
    if err != nil {
        log.Fatal(err)
    }

    res, err := client.Interactions.Create(ctx, operations.CreateInteractionRequest{
        Body: operations.NewCreateInteractionRequestBody(interactions.CreateModelInteraction{
            Model: interactions.Model("gemini-3.8-flash"),
            Input: interactions.NewInteractionsInput("Write a haiku about coding."),
        }),
    })
    if err != nil {
        log.Fatal(err)
    }

    if res.Interaction.OutputText != nil {
        fmt.Println(*res.Interaction.OutputText)
    }
}

REST

curl -X POST "https://generativelanguage.googleapis.com/v1beta/interactions?alt=sse" \
  -H "x-goog-api-key: $GEMINI_API_KEY" \
  -H 'Content-Type: application/json' \
  --no-buffer \
  -d '{
    "model": "gemini-3.8-flash",
    "input": "Explain how AI works",
    "stream": true
  }'

Durante lo streaming, il server risponde con un flusso di eventi inviati dal server (SSE). Ogni evento include un tipo e dati JSON.

Risposta:

event: interaction.created
data: {"interaction":{"id":"v1_Chd...","status":"in_progress","model":"gemini-3.8-flash"},"event_type":"interaction.created"}

event: step.start
data: {"index":0,"step":{"type":"thought"},"event_type":"step.start"}

event: step.delta
data: {"index":0,"delta":{"signature":"EvEFCu4F...","type":"thought_signature"},"event_type":"step.delta"}

event: step.stop
data: {"index":0,"event_type":"step.stop"}

event: step.start
data: {"index":1,"step":{"type":"model_output"},"event_type":"step.start"}

event: step.delta
data: {"index":1,"delta":{"text":"AI ","type":"text"},"event_type":"step.delta"}

event: step.delta
data: {"index":1,"delta":{"text":"works ","type":"text"},"event_type":"step.delta"}

event: step.stop
data: {"index":1,"event_type":"step.stop"}

event: interaction.completed
data: {"interaction":{"id":"v1_Chd...","status":"completed","usage":{"total_tokens":197}},"event_type":"interaction.completed"}

4. Conversazioni a più turni

L'API Interactions supporta le conversazioni multi-turno con due approcci:

Stateful (consigliato): continua una conversazione sul server utilizzando previous_interaction_id. Ideale per la maggior parte dei workflow di chat e agentici in cui vuoi che il server gestisca la cronologia e ottimizzi la memorizzazione nella cache.
Senza stato: gestisci la cronologia della conversazione sul client passando tutti i turni precedenti (inclusi i passaggi intermedi del modello e dello strumento) in ogni richiesta.

Stateful (consigliato)

Concatenare le interazioni passando previous_interaction_id. Il server gestisce l'intera cronologia delle conversazioni per te.

Python

from google import genai

client = genai.Client()

# Server-side state (recommended)
interaction1 = client.interactions.create(
    model="gemini-3.8-flash",
    input="I have 2 dogs in my house.",
)
print("Response 1:", interaction1.output_text)

interaction2 = client.interactions.create(
    model="gemini-3.8-flash",
    input="How many paws are in my house?",
    previous_interaction_id=interaction1.id,
)
print("Response 2:", interaction2.output_text)

JavaScript

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

Stateless

Imposta store=false e gestisci la cronologia delle conversazioni sul lato client. Devi conservare e inviare nuovamente tutti i passaggi generati dal modello (inclusi i passaggi thought e function_call) esattamente come li hai ricevuti.

Python

from google import genai

    {
        "type": "user_input",
        "content": [{"type": "text", "text": "I have 2 dogs in my house."}]

5. Comprensione multimodale

I modelli Gemini comprendono immagini, audio, video e documenti in modo nativo. Passa contenuti multimediali insieme al testo in un'unica richiesta.

interaction = client.interactions.create(
    model="gemini-3.8-flash",
    input=[
        {"type": "text", "text": "Compare this local image and this remote audio file."},
        {

Quando il modello genera un'immagine, restituisce i dati immagine codificati in base64 in un passaggio all'interno dell'array steps, nonché tramite la proprietà di convenienza output_image. Consulta la guida alla generazione di immagini per scoprire di più su proporzioni, modifica delle immagini e riferimenti.

7. Utilizzare l'output strutturato

Configura il modello in modo che restituisca JSON che corrisponda a uno schema che definisci. L'output strutturato funziona con Pydantic (Python) e Zod (JavaScript).

Python

from google import genai
from pydantic import BaseModel, Field
from typing import List, Optional

class Recipe(BaseModel):
    recipe_name: str = Field(description="Name of the recipe.")
    ingredients: List[str] = Field(description="List of ingredients.")
    prep_time_minutes: Optional[int] = Field(description="Prep time in minutes.")

client = genai.Client()

interaction = client.interactions.create(
    model="gemini-3.8-flash",
    input="Give me a recipe for banana bread",
    response_format={
        "type": "text",
        "mime_type": "application/json",
        "schema": Recipe.model_json_schema()
    },
)

recipe = Recipe.model_validate_json(interaction.output_text)
print(recipe)

JavaScript

import { GoogleGenAI } from "@google/genai";
import * as z from "zod";

const ai = new GoogleGenAI({});

const recipeJsonSchema = {
  type: "object",
  properties: {
    recipe_name: { type: "string", description: "Name of the recipe." },
    ingredients: {
      type: "array",
      items: { type: "string" },
      description: "List of ingredients."
    },
    prep_time_minutes: {
      type: "integer",
      description: "Prep time in minutes."
    }
  },
  required: ["recipe_name", "ingredients"]
};

const recipeSchema = z.fromJSONSchema(recipeJsonSchema);

const interaction = await ai.interactions.create({
  model: "gemini-3.8-flash",
  input: "Give me a recipe for banana bread",
  response_format: {
    type: "text",
    mime_type: "application/json",
    schema: recipeJsonSchema
  },
});

const recipe = recipeSchema.parse(JSON.parse(interaction.output_text));
console.log(recipe);

8. Utilizzare gli strumenti

Basare la risposta del modello su informazioni in tempo reale con la Ricerca Google. L'API esegue automaticamente la ricerca, elabora i risultati e restituisce le citazioni.

Python

from google import genai

client = genai.Client()

interaction = client.interactions.create(
    model="gemini-3.8-flash",
    input="Who won the euro 2024?",
    tools=[{"type": "google_search"}]
)

print(interaction.output_text)

Stateless

Puoi anche utilizzare la chiamata di funzioni in modalità stateless gestendo la cronologia della conversazione sul lato client e impostando store=false. In modalità stateless, devi trasmettere la cronologia completa della conversazione nel campo input di ogni richiesta successiva. Questa cronologia deve includere:

Il passaggio iniziale user_input.
Tutti i passaggi generati dal modello restituiti nel Turno 1 (inclusi i passaggi thought e function_call) esattamente come ricevuti.
Il passaggio function_result contenente l'output della funzione eseguita.

Risposta:

Durante il turno 1, il modello restituisce una risposta con stato requires_action e il passaggio function_call:

{
  "id": "v1_Chd...",
  "status": "requires_action",
  "steps": [
    {
      "type": "function_call",
