Tuning

Gemini API 的微調支援提供一種機制,可在您的輸入/輸出樣本小型資料集時彙整輸出內容。詳情請參閱模型調整指南教學課程

方法:tunedModels.create

建立調整後的模型。透過 google.longrunning.Operations 服務查看中繼調整進度 (如有)。

透過「作業」服務存取狀態和結果。範例:GET /v1/tunedModels/az2mb0bpw6i/operations/000-111-222

端點

post https://generativelanguage.googleapis.com/v1beta/tunedModels

查詢參數

tunedModelId string

選用設定。調整後模型的專屬 ID (如有指定)。這個值的長度上限為 40 個字元,第一個字元必須是英文字母,最後一個字元可以是英文字母或數字。ID 必須與規則運算式相符:[a-z]([a-z0-9-]{0,38}[a-z0-9])?

要求主體

要求主體包含 TunedModel 的例項。

欄位
displayName string

選用設定。在使用者介面中顯示此模型的名稱。顯示名稱的長度上限為 40 個半形字元 (包含空格)。

description string

選用設定。這個模型的簡短說明。

tuningTask object (TuningTask)

必要欄位。建立調整後模型的調整工作。

readerProjectNumbers[] string (int64 format)

選用設定。具備調整後模型讀取權限的專案編號清單。

聯集欄位 source_model。用來調整模型的起點。source_model 只能採用下列其中一種設定:
tunedModelSource object (TunedModelSource)

選用設定。使用 TunedModel 做為訓練新模型的起點。

baseModel string

不可變動。要調整的 Model 名稱。範例:models/gemini-1.5-flash-001

temperature number

選用設定。控管輸出內容的隨機程度。

值的範圍可以超過 [0.0,1.0] (含首尾)。值越接近 1.0,產生的回覆就會越多元;值越接近 0.0,模型產生的回覆就會越少。

這個值會指定基礎模型在建立模型時採用的預設值。

topP number

選用設定。用於 Nucleus 取樣。

Nucleus 取樣會考量機率總和至少為 topP 的最小符記集。

這個值會將預設值指定為基本模型在建立模型時使用的值。

topK integer

選用設定。用於 Top-K 取樣。

前 K 大取樣會考量機率最高的 topK 符記組合。這個值會指定在呼叫模型時,後端會使用的預設值。

這個值會指定基礎模型在建立模型時採用的預設值。

要求範例

base_model = "models/gemini-1.5-flash-001-tuning"
training_data = [
    {"text_input": "1", "output": "2"},

result = model.generate_content("III")
print(result.text)  # IV

回應主體

這個資源表示屬於網路 API 呼叫結果的長時間執行作業。

如果成功,回應主體會含有以下結構的資料:

欄位
name string

伺服器指派的名稱,而且只在當初傳回這個名稱的服務中是唯一的。如果您使用預設的 HTTP 對應,name 應為結尾為 operations/{unique_id} 的資源名稱。

metadata object

服務專屬,且與該作業相關聯的中繼資料,通常包含進度資訊和常用中繼資料 (例如建立時間)。部分服務可能不會提供這類中繼資料。凡是會傳回長時間執行作業的方法,都應記錄中繼資料類型 (如果有的話)。

包含任意類型欄位的物件。額外的 "@type" 欄位則包含能辨識類型的 URI。範例:{ "id": 1234, "@type": "types.example.com/standard/id" }

done boolean

如果值為 false,代表作業仍在執行中。如果值為 true,表示作業已完成,且會顯示 errorresponse

聯集欄位 result。這是作業的執行結果,可能為 error,或是有效的 response。如果 done == false,系統不會將結果設定為 error,也不會設定為 response。如果 done == true,則可設定 errorresponse 其中一個。部分服務可能不會提供結果。result 只能採用下列其中一種設定:
error object (Status)

作業失敗或取消時顯示的錯誤結果。

response object

作業成功時的一般回應。如果原始方法在執行成功時沒有傳回資料 (例如 Delete),則回應為 google.protobuf.Empty。如果原始方法是標準的 Get/Create/Update,回應則應該為資源。如果是其他方法,回應必須包含類型 XxxResponse,其中 Xxx 是原始方法的名稱。舉例來說,如果原始方法的名稱為 TakeSnapshot(),您就能推測出回應類型應該是 TakeSnapshotResponse

包含任意類型欄位的物件。額外的 "@type" 欄位則包含能辨識類型的 URI。範例:{ "id": 1234, "@type": "types.example.com/standard/id" }

JSON 表示法
{
  "name": string,
  "metadata": {
    "@type": string,
    field1: ...,
    ...
  },
  "done": boolean,

  // Union field result can be only one of the following:
  "error": {
    object (Status)
  },
  "response": {
    "@type": string,
    field1: ...,
    ...
  }
  // End of list of possible types for union field result.
}

方法:tunedModels.generateContent

根據輸入的 GenerateContentRequest 產生模型回應。如需詳細使用資訊,請參閱文字產生指南。不同模型的輸入功能不同,包括經過調整的模型。詳情請參閱模型指南調整指南

端點

則貼文 https://generativelanguage.googleapis.com/v1beta/{model=tunedModels/*}:generateContent

路徑參數

model string

必要欄位。用於產生完成項目的 Model 名稱。

格式:name=models/{model}。格式為 tunedModels/{tunedmodel}

要求主體

要求主體的資料會採用以下結構:

欄位
contents[] object (Content)

必要欄位。與模型目前對話的內容。

對於單次查詢,這會是單一例項。對於chat 等多輪查詢,這個欄位是重複欄位,其中包含對話記錄和最新要求。

tools[] object (Tool)

選用設定。Model 可以用來產生下一次回應的 Tools 清單。

Tool 是一段程式碼,可讓系統與外部系統互動,在 Model 知識和範圍外,執行動作或一組動作。支援的 ToolFunctioncodeExecution。詳情請參閱「函式呼叫」和「程式碼執行」指南。

toolConfig object (ToolConfig)

選用設定。要求中指定的任何 Tool 工具設定。如需使用範例,請參閱函式呼叫指南

safetySettings[] object (SafetySetting)

選用設定。用於封鎖不安全內容的不重複 SafetySetting 執行個體清單。

這將在 GenerateContentRequest.contentsGenerateContentResponse.candidates強制執行。每個 SafetyCategory 類型只能有一項設定。API 會封鎖任何不符合這些設定所設門檻的內容和回應。這份清單會覆寫 safetySettings 中指定的每個 SafetyCategory 的預設設定。如果清單中提供的特定 SafetyCategory 沒有 SafetySetting,API 就會使用該類別的預設安全設定。系統支援的危害類別包括 HARM_CATEGORY_HATE_SPEECH、HARM_CATEGORY_SEXUALLY_EXPLICIT、HARM_CATEGORY_DANGEROUS_CONTENT 和 HARM_CATEGORY_HARASSMENT。如要進一步瞭解可用的安全設定,請參閱指南。另請參閱安全指南,瞭解如何在 AI 應用程式中加入安全考量。

systemInstruction object (Content)

選用設定。開發人員設定系統操作說明。目前僅支援文字。

generationConfig object (GenerationConfig)

選用設定。模型產生和輸出的設定選項。

cachedContent string

選用設定。快取的內容名稱,用於做為預測的上下文。格式:cachedContents/{cachedContent}
