Generating content

L'API Gemini supporta la generazione di contenuti con immagini, audio, codice, strumenti e altro ancora. Per i dettagli su ciascuna di queste funzionalità, continua a leggere e consulta il codice di esempio specifico per le attività oppure leggi le guide complete.

Metodo: model.generateContent

Genera una risposta del modello dato un input GenerateContentRequest. Per informazioni dettagliate sull'utilizzo, consulta la guida alla generazione del testo. Le funzionalità di input variano tra i modelli, inclusi i modelli ottimizzati. Per maggiori dettagli, consulta la guida ai modelli e la guida all'ottimizzazione.

Endpoint

pubblica https://generativelanguage.googleapis.com/v1beta/{model=models/*}:generateContent

Parametri del percorso

model string

Obbligatorio. Il nome dell'evento Model da utilizzare per generare il completamento.

Formato: name=models/{model}. Il formato è models/{model}.

Corpo della richiesta

Il corpo della richiesta contiene dati con la seguente struttura:

Campi
contents[] object (Content)

Obbligatorio. I contenuti della conversazione corrente con il modello.

Per le query a turno singolo, si tratta di una singola istanza. Per le query in più passaggi come la chat, si tratta di un campo ripetuto che contiene la cronologia della conversazione e l'ultima richiesta.

tools[] object (Tool)

(Facoltativo) Un elenco di Tools che Model può utilizzare per generare la risposta successiva.

Un Tool è una porzione di codice che consente al sistema di interagire con sistemi esterni per eseguire un'azione o un insieme di azioni al di fuori delle conoscenze e dell'ambito di Model. I valori di tipo Tool supportati sono Function e codeExecution. Per saperne di più, consulta le Chiamate di funzione e le guide sull'esecuzione del codice.

toolConfig object (ToolConfig)

(Facoltativo) Configurazione dello strumento per qualsiasi Tool specificato nella richiesta. Per un esempio di utilizzo, consulta la guida alla chiamata di funzione.

safetySettings[] object (SafetySetting)

(Facoltativo) Un elenco di istanze SafetySetting univoche per il blocco di contenuti non sicuri.

Questa norma verrà applicata in modo forzato a GenerateContentRequest.contents e GenerateContentResponse.candidates. Non dovrebbe essere presente più di un'impostazione per ogni tipo di SafetyCategory. L'API bloccherà tutti i contenuti e le risposte che non rispetteranno le soglie impostate da queste impostazioni. Questo elenco sostituisce le impostazioni predefinite per ogni SafetyCategory specificato in safetySettings. Se non è presente alcun valore SafetySetting per un determinato SafetyCategory nell'elenco, l'API utilizzerà l'impostazione di sicurezza predefinita per la categoria in questione. Sono supportate le categorie di danni HARM_CATEGORY_HATE_SPEECH, HARM_CATEGORY_SEXUALLY_EXPLICIT, HARM_CATEGORY_DANGEROUS_CONTENT e HARM_CATEGORY_HARASSMENT. Consulta la guida per informazioni dettagliate sulle impostazioni di sicurezza disponibili. Consulta anche le indicazioni sulla sicurezza per scoprire come incorporare le considerazioni sulla sicurezza nelle tue applicazioni di IA.

systemInstruction object (Content)

(Facoltativo) Lo sviluppatore ha impostato le istruzioni di sistema. Al momento, solo testo.

generationConfig object (GenerationConfig)

(Facoltativo) Opzioni di configurazione per la generazione e gli output del modello.

cachedContent string

(Facoltativo) Il nome dei contenuti memorizzati nella cache da utilizzare come contesto per la previsione. Formato: cachedContents/{cachedContent}

Corpo della risposta

In caso di esito positivo, il corpo della risposta contiene un'istanza di GenerateContentResponse.

Metodo: models.streamGenerateContent

Genera una risposta in modalità flusso dal modello a cui è stato dato un input GenerateContentRequest.

Endpoint

pubblica https://generativelanguage.googleapis.com/v1beta/{model=models/*}:streamGenerateContent

Parametri del percorso

model string

Obbligatorio. Il nome dell'evento Model da utilizzare per generare il completamento.

Formato: name=models/{model}. Il formato è models/{model}.

Corpo della richiesta

Il corpo della richiesta contiene dati con la seguente struttura:

Campi
contents[] object (Content)

Obbligatorio. I contenuti della conversazione corrente con il modello.

Per le query a turno singolo, si tratta di una singola istanza. Per le query in più passaggi come la chat, si tratta di un campo ripetuto che contiene la cronologia della conversazione e l'ultima richiesta.

tools[] object (Tool)

(Facoltativo) Un elenco di Tools che Model può utilizzare per generare la risposta successiva.

Un Tool è una porzione di codice che consente al sistema di interagire con sistemi esterni per eseguire un'azione o un insieme di azioni al di fuori delle conoscenze e dell'ambito di Model. I valori di tipo Tool supportati sono Function e codeExecution. Per saperne di più, consulta le Chiamate di funzione e le guide sull'esecuzione del codice.

toolConfig object (ToolConfig)

(Facoltativo) Configurazione dello strumento per qualsiasi Tool specificato nella richiesta. Per un esempio di utilizzo, consulta la guida alla chiamata di funzione.

safetySettings[] object (SafetySetting)

(Facoltativo) Un elenco di istanze SafetySetting univoche per il blocco di contenuti non sicuri.

Questa norma verrà applicata in modo forzato a GenerateContentRequest.contents e GenerateContentResponse.candidates. Non dovrebbe essere presente più di un'impostazione per ogni tipo di SafetyCategory. L'API bloccherà tutti i contenuti e le risposte che non rispetteranno le soglie impostate da queste impostazioni. Questo elenco sostituisce le impostazioni predefinite per ogni SafetyCategory specificato in safetySettings. Se non è presente alcun valore SafetySetting per un determinato SafetyCategory nell'elenco, l'API utilizzerà l'impostazione di sicurezza predefinita per la categoria in questione. Sono supportate le categorie di danni HARM_CATEGORY_HATE_SPEECH, HARM_CATEGORY_SEXUALLY_EXPLICIT, HARM_CATEGORY_DANGEROUS_CONTENT e HARM_CATEGORY_HARASSMENT. Consulta la guida per informazioni dettagliate sulle impostazioni di sicurezza disponibili. Consulta anche le indicazioni sulla sicurezza per scoprire come incorporare le considerazioni sulla sicurezza nelle tue applicazioni di IA.

systemInstruction object (Content)

(Facoltativo) Lo sviluppatore ha impostato le istruzioni di sistema. Al momento, solo testo.

generationConfig object (GenerationConfig)

(Facoltativo) Opzioni di configurazione per la generazione e gli output del modello.

cachedContent string

(Facoltativo) Il nome dei contenuti memorizzati nella cache da utilizzare come contesto per la previsione. Formato: cachedContents/{cachedContent}

Esempio di richiesta

Corpo della risposta

In caso di esito positivo, il corpo della risposta contiene un flusso di istanze GenerateContentResponse.

GenerateContentResponse

Risposta del modello che supporta più risposte dei candidati.

Le classificazioni di sicurezza e il filtro dei contenuti vengono segnalati sia per la richiesta in GenerateContentResponse.prompt_feedback sia per ogni candidato in finishReason e in safetyRatings. L'API: - Restituisce tutti i candidati richiesti o nessuno di essi - Non restituisce nessun candidato solo se si è verificato un problema con la richiesta (seleziona promptFeedback) - Segnala feedback su ogni candidato in finishReason e safetyRatings.

topP number

(Facoltativo) La probabilità cumulativa massima dei token da considerare durante il campionamento.

Il modello utilizza un campionamento combinato di Top-k e Top-p (nucleo).

I token vengono ordinati in base alle probabilità assegnate in modo che vengano presi in considerazione solo i token più probabili. Il campionamento top-k limita direttamente il numero massimo di token da considerare, mentre il campionamento Nucleo limita il numero di token in base alla probabilità cumulativa.

Nota: il valore predefinito varia in base a Model ed è specificato dall'attributo Model.top_p restituito dalla funzione getModel. Un attributo topK vuoto indica che il modello non applica il campionamento top-k e non consente di impostare topK sulle richieste.

topK integer

(Facoltativo) Il numero massimo di token da considerare durante il campionamento.

I modelli Gemini utilizzano il campionamento Top-p (nucleo) o una combinazione di campionamento Top-k e nucleo. Il campionamento Top-k prende in considerazione l'insieme di topK token più probabili. I modelli in esecuzione con il campionamento del nucleo non consentono l'impostazione di topK.

Nota: il valore predefinito varia in base a Model ed è specificato dall'attributo Model.top_p restituito dalla funzione getModel. Un attributo topK vuoto indica che il modello non applica il campionamento top-k e non consente di impostare topK sulle richieste.
