Counting tokens

Pour obtenir un guide détaillé sur le décompte des jetons à l'aide de l'API Gemini, y compris sur la façon dont les images, l'audio et la vidéo sont comptabilisés, consultez le guide sur le décompte des jetons et la recette de Cookbook associée.

Méthode : models.countTokens

Exécute le tokenizer d'un modèle sur l'entrée Content et renvoie le nombre de jetons. Pour en savoir plus sur les jetons, consultez le guide sur les jetons.

Point de terminaison

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

Paramètres de chemin d'accès

model string

Obligatoire. Nom de ressource du modèle. Il sert d'ID pour le modèle à utiliser.

Ce nom doit correspondre à un nom de modèle renvoyé par la méthode models.list.

Format : models/{model}. Il prend la forme models/{model}.

Corps de la requête

Le corps de la requête contient des données présentant la structure suivante :

Champs
contents[] object (Content)

Facultatif. Entrée fournie au modèle en tant que prompt. Ce champ est ignoré lorsque generateContentRequest est défini.

generateContentRequest object (GenerateContentRequest)

Facultatif. Entrée globale fournie au Model. Cela inclut le prompt, ainsi que d'autres informations de pilotage du modèle, telles que les instructions système et/ou les déclarations de fonction pour l'appel de fonction. Les Models/Contents et les generateContentRequests s'excluent mutuellement. Vous pouvez envoyer des Model + Contents ou une generateContentRequest, mais jamais les deux.
