Mit Funktionsaufrufen können Sie Modelle mit externen Tools und APIs verbinden. Anstatt Textantworten zu generieren, bestimmt das Modell, wann bestimmte Funktionen aufgerufen werden sollen, und stellt die erforderlichen Parameter zum Ausführen von Aktionen in der realen Welt bereit. So kann das Modell als Brücke zwischen natürlicher Sprache und realen Aktionen und Daten fungieren. Funktionsaufrufe haben drei primäre Anwendungsfälle:
- Aktionen ausführen:Über APIs mit externen Systemen interagieren, z. B. Termine planen, Rechnungen erstellen, E‑Mails senden oder Smart-Home-Geräte steuern.
- Wissen erweitern:Zugriff auf Informationen aus externen Quellen wie Datenbanken, APIs und Wissensdatenbanken.
- Funktionen erweitern:Verwenden Sie externe Tools, um Berechnungen durchzuführen und die Einschränkungen des Modells zu erweitern, z. B. durch die Verwendung eines Taschenrechners oder das Erstellen von Diagrammen.
Unten finden Sie Beispiele für diese Anwendungsfälle:
Besprechung planen
In diesem Beispiel wird gezeigt, wie Sie eine Funktion definieren, mit der eine Besprechung mit Teilnehmern zu einem bestimmten Zeitpunkt geplant wird. So kann das Modell Nutzeranfragen parsen und strukturierte Argumente zurückgeben, um Aktionen in externen Systemen auszulösen.

Funktionsweise von Funktionsaufrufen
Funktionsaufrufe umfassen eine strukturierte Interaktion zwischen Ihrer Anwendung, dem Modell und externen Funktionen:
- Funktionsdeklaration definieren:Definieren Sie den Namen, die Parameter und den Zweck der Funktion für das Modell.
- LLM mit Funktionsdeklarationen aufrufen:Senden Sie den Nutzer-Prompt zusammen mit den Funktionsdeklarationen an das Modell.
- Funktionscode ausführen (Ihre Verantwortung): Das Modell führt die Funktion nicht selbst aus. Extrahieren Sie den Namen und die Argumente und führen Sie sie in Ihrer Anwendung aus.
- Nutzerfreundliche Antwort erstellen:Senden Sie das Ergebnis zurück an das Modell, um eine endgültige, nutzerfreundliche Antwort zu erhalten.
Dieser Vorgang kann über mehrere Züge hinweg wiederholt werden. Das Modell unterstützt das Aufrufen mehrerer Funktionen in einer einzelnen Runde (paralleler Funktionsaufruf) und in einer Sequenz (zusammengesetzter Funktionsaufruf).
Schritt 1: Funktionsdeklaration definieren

Zustandslose Funktionsaufrufe
Sie können Funktionsaufrufe auch im statuslosen Modus verwenden, indem Sie den Unterhaltungsverlauf clientseitig verwalten und store=false festlegen.
Im zustandslosen Modus müssen Sie den vollständigen Verlauf der Unterhaltung im Feld input jeder nachfolgenden Anfrage übergeben. Dieser Verlauf muss Folgendes enthalten:
1. Der erste Schritt user_input.
2. Alle vom Modell generierten Schritte, die in Turn 1 zurückgegeben werden (einschließlich der Schritte thought und function_call), werden genau so zurückgegeben, wie sie empfangen wurden.
3. Der function_result-Schritt, der die Ausgabe Ihrer ausgeführten Funktion enthält.

Funktionsdeklarationen
Eine Funktionsdeklaration wird als Tool übergeben und enthält Folgendes:
type(String): Muss für benutzerdefinierte Funktionen"function"sein.name(String): Eindeutiger Funktionsname (Unterstriche oder CamelCase verwenden).description(String): Klare Erläuterung des Zwecks der Funktion.parameters(Objekt): Eingabeparameter, die die Funktion erwartet.type(String): Gesamtdatentyp, z. B.object.properties(Objekt): Einzelne Parameter mit Typ und Beschreibung.required(Array): Namen der Pflichtparameter.
Funktionsaufrufe mit Thinking-Modellen
Die Modelle der Gemini 3-Serie verwenden einen internen Denkprozess, der Funktionsaufrufe verbessert. Die SDKs verarbeiten Gedankensignaturen automatisch für Sie.
Parallele Funktionsaufrufe
Rufen Sie mehrere Funktionen gleichzeitig auf, wenn sie unabhängig voneinander sind:

Modi für Funktionsaufrufe
Mit tool_choice in generation_config können Sie festlegen, wie das Modell Tools verwendet:
auto(Standard): Das Modell entscheidet, ob eine Funktion aufgerufen oder direkt geantwortet werden soll.any: Das Modell ist darauf beschränkt, immer einen Funktionsaufruf vorherzusagen.none: Das Modell darf keine Funktionsaufrufe ausführen.validated: Das Modell sorgt für die Einhaltung des Funktionsschemas.

Verwendung von mehreren Tools
Sie können mehrere Tools aktivieren und integrierte Tools mit Funktionsaufrufen in derselben Anfrage kombinieren. Gemini 3-Modelle können integrierte Tools mit Funktionsaufrufen in Interaktionen kombinieren. Wenn Sie previous_interaction_id übergeben, wird der integrierte Tool-Kontext automatisch weitergegeben.

Multimodale Funktionsantworten
Bei Modellen der Gemini 3-Serie können Sie multimodale Inhalte in die Funktionsantwortteile einfügen, die Sie an das Modell senden. Das Modell kann diese multimodalen Inhalte in seinem nächsten Zug verarbeiten, um eine fundiertere Antwort zu generieren.
Wenn Sie multimodale Daten in eine Funktionsantwort einfügen möchten, müssen Sie sie als einen oder mehrere Inhaltsblöcke im Feld result des Schritts function_result angeben. Für jeden Inhaltsblock muss die type angegeben werden (z.B. "text", "image").
Das folgende Beispiel zeigt, wie Sie in einer Interaktion eine Funktionsantwort mit Bilddaten an das Modell zurücksenden:
Python

Funktionsaufrufe mit strukturierter Ausgabe
Bei Modellen der Gemini 3-Serie können Sie Funktionsaufrufe mit strukturierter Ausgabe kombinieren, um konsistent formatierte Antworten zu erhalten.
Remote-MCP (Model Context Protocol)
Die Interactions API unterstützt die Verbindung mit Remote-MCP-Servern, um dem Modell Zugriff auf externe Tools und Dienste zu ermöglichen. Sie geben den Server name und url in der Tools-Konfiguration an.
Beachten Sie bei der Verwendung von Remote MCP die folgenden Einschränkungen:
- Servertypen: Remote-MCP funktioniert nur mit streamfähigen HTTP-Servern. SSE-Server (Server-Sent Events) werden nicht unterstützt.
- Benennung: MCP-Servernamen dürfen das Zeichen
-nicht enthalten. Verwenden Sie stattdessensnake_case-Servernamen.
| Feld | Typ | Erforderlich | Beschreibung |
|---|---|---|---|
type |
string |
Ja | Muss "mcp_server" lauten. |
name |
string |
Nein | Ein Anzeigename für den MCP-Server. |
url |
string |
Nein | Die vollständige URL für den MCP-Serverendpunkt. |
headers |
object |
Nein | Schlüssel/Wert-Paare, die mit jeder Anfrage an den Server als HTTP-Header gesendet werden (z. B. Authentifizierungstokens). |
allowed_tools |
array |
Nein | Einschränken, welche Tools vom Server der Agent aufrufen darf. |

Toolaufrufe streamen
Wenn Sie Tools mit Streaming verwenden, generiert das Modell Funktionsaufrufe als Folge von step.delta-Ereignissen im Stream. Toolargumente können mit arguments als partielle Argumente gestreamt werden. Sie müssen diese Deltas zusammenfassen, um die vollständigen Tool-Aufrufe zu rekonstruieren, bevor Sie sie ausführen.

Best Practices
- Funktions- und Parameterbeschreibungen:Formulieren Sie klar und präzise.
- Benennung:Verwenden Sie aussagekräftige Namen ohne Leerzeichen oder Sonderzeichen.
- Strikte Typisierung:Verwenden Sie bestimmte Typen (Ganzzahl, String, Enum).
- Toolauswahl:Halten Sie die Anzahl der aktiven Tools auf maximal 10 bis 20.
- Prompt Engineering:Geben Sie Kontext und Anweisungen an.
- Validierung:Funktionsaufrufe vor der Ausführung validieren.
- Fehlerbehandlung:Implementieren Sie eine robuste Fehlerbehandlung.
- Sicherheit:Verwenden Sie eine geeignete Authentifizierung für externe APIs.
Problemumgehungen für Textanforderungen vor der Verwendung des Tools
Problem:Wenn in Ihrem Prompt das Modell aufgefordert wird, strukturierten Text (XML, YAML, JSON usw.) auszugeben. Wenn Sie beispielsweise <UPDATE>...</UPDATE> unmittelbar vor einem Tool-Aufruf verwenden, kann der Tool-Aufruf gelegentlich mit Malformed_Function_Call fehlschlagen.
Lösungen: Die folgenden Behelfslösungen beheben dieses Problem:
- VORZUGSWEISE:Weisen Sie das Modell an, seine Notizen vor dem Tool in einem dedizierten
update()-Funktionsaufruf anstelle von Rohtext zu platzieren (siehe unten). - Weisen Sie das Modell an, Notizen als Markdown-Überschriften (
# UPDATE,## PLAN) anstelle von strukturiertem Text zu schreiben. - Das Modell muss vor Tool-Aufrufen keinen Text ausgeben.
Bevorzugte Problemumgehung: Arbeitsnotizen in einen dedizierten Funktionsaufruf einfügen
Anstelle der ursprünglichen Anleitung:
Before calling a tool, in every response you MUST first output a single `<UPDATE>` part as specified, don't skip this part or any of required sub-tags within `<UPDATE>`.
Verwenden Sie diese aktualisierte Anleitung:
Before calling any other tool, in every response you MUST first call `update` with all required parameters (previous_step, plan, next_step, external).
Aktualisieren Sie alle Verweise auf das alte <UPDATE>-XML-Format in der Kundenanfrage. Fügen Sie dann die entsprechende Funktionsdeklaration für die Update-Funktion hinzu:
{
"name": "update",
"description": "Update working notes (previous step analysis, plan, next step, external note).",
"parameters": {
"type": "OBJECT",
"properties": {
"previous_step": {
"type": "STRING",
"description": "Key findings and outcomes since the previous step."
},
"plan": {
"type": "STRING",
"description": "The current status of the plan."
},
"next_step": {
"type": "STRING",
"description": "Brief explanation of the immediate next action according to the plan."
},
"external": {
"type": "STRING",
"description": "A short, plain-language note shown to the User about what you are ABOUT TO DO next."
}
},
"required": [
"previous_step",
"plan",
"next_step",
"external"
]
}
}
Das Modell führt dann im selben Schritt zwei Aufrufe aus: den update()-Aufruf, der das strukturierte XML ersetzt, und den eigentlichen Funktionsaufruf, den es ausführen möchte.
Hinweise und Einschränkungen
- Es wird nur eine Teilmenge des OpenAPI-Schemas unterstützt.
- Im
any-Modus lehnt die API möglicherweise sehr große oder tief verschachtelte Schemas ab. - Die unterstützten Parametertypen in Python sind begrenzt.
