透過 Apple 的 Foundation Models 架構存取 Gemini API 時,您可以為 Gemini 模型提供 Gemini 內建工具,將模型連結至外部資料來源。
本頁說明如何使用下列 Gemini 模型內建工具:
使用Google Search 建立基準
使用
如需詳細資料、最佳做法和用途,請參閱使用
支援的模型
gemini-4-argongemini-3.8-flashgemini-3.5-flash-lite(以及舊版gemini-3.1-flash-lite)gemini-nano-banana-2.1(Nano Banana 2.1)gemini-3.1-flash-image(Nano Banana 2)gemini-3-pro-image(Nano Banana Pro)
舊版一般用途 Gemini 3.x Flash 模型支援這項功能,但由於即將停用和/或自動轉送至新版模型,因此不建議使用。
啟用「Google Search 」工具
在建立 geminiLanguageModel 時提供 googleSearch 工具:
import FoundationModels
import FirebaseCore
import FirebaseAILogic
// Initialize the Gemini Developer API backend service.
let ai = FirebaseAI.firebaseAI(backend: .googleAI())
// Initialize a `geminiLanguageModel` with a Gemini model that supports your use case.
let model = ai.geminiLanguageModel(
name: "GEMINI_MODEL_NAME",
// Provide Google Search as a tool that the model can use to generate its response.
serverTools: [GeminiTool.googleSearch()]
)
let session = LanguageModelSession(model: model)
let response = try await session.respond(to: "What is the weather in Toronto today?")
for entry in response.transcriptEntries {
if case let .response(responseEntry) = entry {
if let groundingMetadata = responseEntry
.metadata["groundingMetadata"] as? GroundingMetadata {
for chunk in groundingMetadata.groundingChunks {
let webChunk = chunk.web
// use the webChunk
}
}
}
}
// Make sure to comply with the "Grounding with Google Search" usage requirements,
// which includes how you use and display the grounded result
使用Google Maps 建立基準

啟用「Google Maps 」工具
在建立 geminiLanguageModel 時提供 googleMaps 工具。您也可以選擇在工具設定中提供座標。
import FoundationModels
import FirebaseCore
import FirebaseAILogic
// Initialize the Gemini Developer API backend service.
let ai = FirebaseAI.firebaseAI(backend: .googleAI())
// Initialize a `geminiLanguageModel` with a Gemini model that supports your use case.

name: "GEMINI_MODEL_NAME",
// Provide Google Maps as a tool that the model can use to generate its response.
serverTools: [GeminiTool.googleMaps()]
)
let session = LanguageModelSession(model: model)
let response = try await session
respond(to: "Where is a good place to grab a coffee near Alameda, CA?")
for entry in response.transcriptEntries {
if case let .response(responseEntry) = entry {
if let groundingMetadata = responseEntry
.metadata["groundingMetadata"] as? GroundingMetadata {
for chunk in groundingMetadata.groundingChunks {
let mapsChunk = chunk.maps
// use the mapsChunk
}
}
}
}
// Make sure to comply with the "Grounding with Google Maps " usage requirements,
// which includes how you meet service usage requirements
