Counting tokens

מדריך מפורט לספירת טוקנים באמצעות Gemini API, כולל הסבר על ספירת תמונות, אודיו וסרטונים, זמין במדריך לספירת טוקנים ובמתכון הנלווה.

שיטה: models.countTokens

מפעילה את טוקנייזר של מודל על קלט Content ומחזירה את מספר הטוקנים. מידע נוסף על טוקנים זמין במדריך לטוקנים.

נקודת קצה

post https://generativelanguage.googleapis.com/v1beta/{model=models/*}:countTokens

פרמטרים של נתיב

model string

חובה. שם המשאב של המודל. המזהה הזה משמש את המודל.

השם הזה צריך להיות זהה לשם של מודל שמוחזר על ידי השיטה models.list.

פורמט: models/{model} הפורמט הוא models/{model}.

גוף הבקשה

גוף הבקשה מכיל נתונים עם המבנה הבא:

Fields
contents[] object (Content)

אופציונלי. הקלט שניתן למודל כהנחיה. המערכת מתעלמת מהשדה הזה אם השדה generateContentRequest מוגדר.

generateContentRequest object (GenerateContentRequest)

אופציונלי. הקלט הכולל שניתן ל-Model. זה כולל את ההנחיה וגם מידע אחר על הכוונת המודל, כמו הוראות מערכת ו/או הצהרות פונקציות לשימוש בפונקציות. Models/Contents ו-generateContentRequests הם מושגים שאינם חופפים. אפשר לשלוח Model + Contents או generateContentRequest, אבל לא את שניהם.

גוף התשובה

תשובה מאת models.countTokens.

הפונקציה מחזירה את tokenCount של המודל עבור prompt.

אם הפעולה מצליחה, גוף התגובה מכיל נתונים במבנה הבא:

שדות
totalTokens integer

מספר הטוקנים שאליהם הטוקן Model מחלק את prompt. תמיד לא שלילי.

cachedContentTokenCount integer

מספר הטוקנים בחלק המאוחסן במטמון של ההנחיה (התוכן המאוחסן במטמון).

promptTokensDetails[] object (ModalityTokenCount)

פלט בלבד. רשימת המודאליות שעובדו בקלט של הבקשה.

cacheTokensDetails[] object (ModalityTokenCount)

פלט בלבד. רשימה של אופנויות שעברו עיבוד בתוכן שנשמר במטמון.
