אינטראקציות עם סטרימינג

כשיוצרים אינטראקציה, אפשר להגדיר את stream: true להזרמה מצטברת של התגובה באמצעות אירועים שנשלחים מהשרת (SSE).

Python

from google import genai

client = genai.Client()

stream = client.interactions.create(
    model="gemini-3-flash-preview",
    input="Count to from 1 to 25.",
    stream=True,
)
for event in stream:
    if event.event_type == "step.delta":
        if event.delta.type == "text":
            print(event.delta.text, end="", flush=True)

JavaScript

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

const client = new GoogleGenAI({});

const stream = await client.interactions.create({
    model: "gemini-3-flash-preview",
    input: "Count to from 1 to 25.",
    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);
        }
    }
}

סוגי אירועים

כל אירוע שנשלח מהשרת כולל שם event_type ונתוני JSON משויכים. ממשק ה-API של האינטראקציות משתמש במודל סימטרי של סטרימינג, שבו כל התוכן – טקסט, קריאות לכלים, חשיבה – עובר דרך אירוע מבוסס-שלבים עקבי.

כל סטרימינג פועל לפי רצף האירועים הזה:

  1. interaction.created: האינטראקציה נוצרת וכוללת מטא-נתונים (מזהה, מודל, סטטוס).
  2. סדרה של שלבים, שכל אחד מהם כולל:
    • אירוע step.start שמציין את סוג השלב (למשל, model_output, thought, function_call).
    • אירוע step.delta אחד או יותר עם נתונים מצטברים של השלב הזה.
    • אירוע step.stop שמסמן את השלב כהושלם.
  3. interaction.completed אירוע עם נתוני usage סיום.

כשמגדירים את הערך stream: false, ה-API מחזיר אובייקט interaction יחיד עם מערך steps. כל אלמנט ב-steps הוא הגרסה המורכבת במלואה של מחזור אחד של step.startstep.delta(s) → step.stop.

interaction.created

האירוע הזה נשלח כשיוצרים אינטראקציה בפעם הראשונה. מכיל את מזהה האינטראקציה, המודל והסטטוס הראשוני.

event: interaction.created
data: {"interaction": {"id": "...", "model": "gemini-3-flash-preview", "status": "in_progress", "object": "interaction"}, "event_type": "interaction.created"}

interaction.status_update

האות הזה מציין מעבר סטטוס ברמת האינטראקציה. יכול להיות שיופיע בין השלבים.

event: interaction.status_update
data: {"interaction_id": "...", "status": "in_progress", "event_type": "interaction.status_update"}

step.start

מציין את תחילתו של שלב חדש. מכיל את השלבים type ו-index. סוג השלב קובע אילו סוגי דלתא צפויים ואיך השלב יופיע בתגובה שלא מועברת בסטרימינג:

סוג השלב סוגי הדלתא הצפויים תיאור
model_output text,‏ image,‏ audio תוכן התשובה הסופית של המודל.
thought thought_signature, thought_summary נימוק לפי שרשרת מחשבות. האפשרות summary מופיעה רק אם האפשרות thinking_summaries מופעלת.
function_call arguments_delta בקשה מהלקוח להפעיל פונקציה. הסטטוס של האינטראקציה מוגדר לrequires_action.
כלים בצד השרת משתנה בהתאם לכלי כלים שה-API מפעיל (לדוגמה, google_search_call, google_search_result, code_execution_call, code_execution_result).

הרשימה המלאה מופיעה בהפניית API של אינטראקציות.

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

במקרה של קריאות לפונקציות, השלב כולל את שם הפונקציה, המזהה שלה וארגומנטים ריקים {}

event: step.start
data: {"index": 0, "step": {"type": "function_call", "id":"un6k8t18", "name": "get_weather", "arguments":{}}, "event_type": "step.start"}

step.delta

נתונים מצטברים של השלב הנוכחי. האובייקט delta מכיל שדה type שקובע את הצורה שלו.

לדוגמה:

text: אסימון טקסט מצטבר משלב model_output:

event: step.delta
data: {"index": 0, "delta": {"type": "text", "text": "Hello, my name is Phil"}, "event_type": "step.delta"}

event: step.delta
data: {"index": 0, "delta": {"type": "text", "text": ", and I live in Germany." }, "event_type": "step.delta"}

image: נתוני תמונה בקידוד Base64 משלב model_output:

event: step.delta
data: {"index": 0, "delta": {"type": "image", "mime_type": "image/jpeg", "data": "/9j/4AAQSkZJRgABAQAAAQABAAD/2wBDAAoHBwgHBgoICAgLCg..."}, "event_type": "step.delta"}

thought_summary: סיכום של תהליך החשיבה משלב thought:

event: step.delta
data: {"index": 0, "delta": {"type": "thought_summary", "content": {"type": "text", "text": "I need to find the GCD..."}}, "event_type": "step.delta"}

arguments_delta: מחרוזת JSON (חלקית) של ארגומנטים לבקשה להפעלת פונקציה. הסכום המצטבר צריך להיות מחושב על סמך שינויים:

event: step.delta
data: {"index": 0, "delta": {"type": "arguments_delta", "arguments": "{\"location\": \"San Francisco, CA\"}"}, "event_type": "step.delta"}

אלה כמה מהסוגים הנפוצים ביותר של דלתא. רשימה מלאה של כל סוגי הדלתא זמינה במאמר Interactions API reference.

step.stop

סימון סוף השלב. הוא מכיל את השלב index.

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

interaction.completed

האירוע נשלח כשהאינטראקציה מסתיימת. מכיל את אובייקט האינטראקציה הסופי עם נתוני usage. במצב לא סטרימינג, זהו אובייקט התגובה ברמה העליונה. לא כולל את steps בתשובה.

event: interaction.completed
data: {"interaction": {"id": "v1_abc123", "status": "completed", "usage": {"total_input_tokens": 7, "total_output_tokens": 12, "total_tokens": 19}}, "event_type": "interaction.completed"}

error

האירוע נשלח כשמתרחשת שגיאה במהלך האינטראקציה. מכיל אובייקט שגיאה עם הודעה וקוד.

event: error
data: {"error":{"message":"Deadline expired before operation could complete.","code":"gateway_timeout"},"event_type":"error"}

שידור באמצעות כלים

ממשק Interactions API תומך בסטרימינג גם עם כלים בצד הלקוח (הפעלת פונקציות) וגם עם כלים בצד השרת (חיפוש Google, הפעלת קוד וכו') בבקשה אחת. במהלך הסטרימינג, הפעלות של כלים מופיעות כשלבים מוקלדים בזרם האירועים. במקרה של קריאות לפונקציות, האירוע step.start מעביר את שם הפונקציה, והאירועים step.delta מעבירים את הארגומנטים כמחרוזות JSON (arguments_delta). כדי לקבל את הארגומנטים המלאים, צריך לצבור את הדלתאות האלה. כלים בצד השרת כמו חיפוש Google מופעלים אוטומטית על ידי ה-API, ויוצרים את השלבים google_search_call ו-google_search_result.

סטרימינג עם בקשה להפעלת פונקציה

כדי לבצע קריאות לפונקציות עם סטרימינג, הלקוח צריך לנהל שיחה מרובת תורות: ‫1. תור 1 (בקשה לפונקציה): קוראים לפונקציה interactions.create עם stream: true ועם tools שהגדרתם. ה-API ישדר שלב function_call. צריך לצבור את מחרוזות ה-JSON של הארגומנטים המצטברים (arguments_delta) מאירועי step.delta עד שהאינטראקציה מסתיימת עם הסטטוס requires_action. 2. תור 2 (שליחת תוצאה): מתקשרים שוב אל interactions.create, מעבירים את previous_interaction_id (שזהה למזהה של האינטראקציה הראשונה) ושולחים בלוק function_result במערך input. הפעולה הזו מחדשת את הסטרימינג, ומאפשרת למודל ליצור את התשובה הסופית.

סטרימינג עם חשיבה

כשהמודל משתמש בחשיבה, תקבלו thought שלבים עם שני סוגים שונים של דלתא: thought_summary (תוכן מצטבר של סיכום טקסט או תמונה) ו-thought_signature (ייצוג מוצפן של ההיגיון הפנימי של המודל, שנשלח כדלתא האחרונה לפני step.stop). אם thinking_summaries מופעל, דלתאות thought_summary מעבירות בסטרימינג סיכום של ההיגיון של המודל. מידע נוסף על חשיבה זמין במדריך החשיבה.

שידור באמצעות סוכנים

‫Interactions API תומך בסוכנים כמו Deep Research. הסוכנים משתמשים ב-background=True ומחזירים תוצאות באופן אסינכרוני, אבל אפשר גם להזרים אינטראקציות עם סוכנים כדי לקבל עדכוני התקדמות ושלבי ביניים בזמן שהם מתרחשים. פרטים נוספים זמינים במדריך ל-Deep Research.

יצירת תמונות בסטרימינג

‫Interactions API תומך בסטרימינג של כמה אופני פלט בו-זמנית. אם תבקשו גם text וגם image ב-response_format, תקבלו באותו הזרם טקסט משולב ותמונות שנוצרו.

בדוגמה הבאה נעשה שימוש ב-gemini-3.1-flash-image-preview (Nano Banana 2) כדי לחפש מידע וליצור סיפור עם איורים משולבים.

טיפול באירועים לא ידועים

בהתאם למדיניות בנושא ניהול גרסאות של ה-API, יכול להיות שנוסיף עם הזמן סוגים חדשים של אירועים וסוגים של שינויים מצטברים. הקוד צריך לטפל בסוגי אירועים לא מוכרים בצורה חלקה – לתעד ולדלג על אירועים שלא מזוהים במקום להציג שגיאה.
