openai go

Golang OpenAI API 用戶端

Golang 原生實現，可輕鬆與 OpenAI API 互動。

https://beta.openai.com/docs/api-reference/

用法

您可以使用環境變數來儲存 API 金鑰

 export OPENAI_KEY=[YOUR_KEY]

若要初始化引擎，請使用下列命令：

 e := openai . New ( os . Getenv ( "OPENAI_KEY" ))

尖端

模型

如果您想使用最強大的模型來產生文字輸出，請確保您使用的是「text-davinci-003」。此模型定義為常數openai.ModelTextDavinci003 。

文字版

您可以使用捆綁包完成+編輯來根據最後的上下文重新產生回應。

 e := openai . New ( os . Getenv ( "OPENAI_KEY" ))
ctx := context . Background ()
completionResp , err := e . Completion ( ctx , & openai. CompletionOptions {
	// Choose model, you can see list of available models in models.go file
	Model : openai . ModelTextDavinci001 ,
	// Number of completion tokens to generate response. By default - 1024
	MaxTokens : 1200 ,
	// Text to completion
	Prompt : [] string { "Write a little bit of Wikipedia. What is that?" },
})

editResp , err := e . Edit ( ctx , & EditOptions {
	Model :       ModelTextDavinci001 ,
	Input :       completionResp . Choices [ 0 ],
	Instruction : "Please rewrite a bit more and add more information about Wikipedia in different aspects. Please build based on that for 4 topics" ,
})

文字補全範例

給出提示後，模型將傳回一個或多個預測完成情況。

注意：預設的完成令牌數量為 1024，如果您想增加或減少此限制，您應該更改MaxTokens參數。

 e := openai . New ( os . Getenv ( "OPENAI_KEY" ))
r , err := e . Completion ( context . Background (), & openai. CompletionOptions {
	// Choose model, you can see list of available models in models.go file
	Model : openai . ModelTextDavinci001 ,
	// Number of completion tokens to generate response. By default - 1024
	MaxTokens : 1200 ,
	// Text to completion
	Prompt : [] string { "Write a little bit of Wikipedia. What is that?" },
})

您將獲得下一個輸出：

{
  "id" : " cmpl-6SrcYDLCVT7xyHKVNuSLNuhRvwOJ1 " ,
  "object" : " text_completion " ,
  "created" : 1672337322 ,
  "model" : " text-davinci-001 " ,
  "choices" : [
    {
      "text" : " nn Wikipedia is a free online encyclopedia, created and edited by volunteers. " ,
      "index" : 0 ,
      "finish_reason" : " stop "
    }
  ],
  "usage" : {
    "prompt_tokens" : 11 ,
    "completion_tokens" : 15 ,
    "total_tokens" : 26
  }
}

要僅獲取文本，您應該使用以下程式碼：

 fmt . Println ( r . Choices [ 0 ]. Text )

所以，完整的程式碼將是：

 package main 


import (
	"context"
	"encoding/json"
	"log"
	"os"
	"testing"
  "github.com/0x9ef/openai-go"
)

func main () {
	e := openai . New ( os . Getenv ( "OPENAI_KEY" ))
	r , err := e . Completion ( context . Background (), & openai. CompletionOptions {
		// Choose model, you can see list of available models in models.go file
		Model : openai . ModelTextDavinci001 ,
		// Text to completion
		Prompt : [] string { "Write a little bit of Wikipedia. What is that?" },
	})

	if b , err := json . MarshalIndent ( r , "" , "  " ); err != nil {
		panic ( err )
	} else {
		fmt . Println ( string ( b ))
	}

	// Wikipedia is a free online encyclopedia, created and edited by volunteers.
	fmt . Println ( "What is the Wikipedia?" , r . Choices [ 0 ]. Text )
}

型號列表/檢索

列出目前可用的型號，並提供每個型號的基本信息，例如所有者和可用性。

 e := openai . New ( os . Getenv ( "OPENAI_KEY" ))
r , err := e . ListModels ( context . Background ())
if err != nil {
	log . Fatal ( err )
}

您將獲得下一個輸出：

{
  "data" : [
    {
      "id" : " babbage " ,
      "object" : " model " ,
      "owned_by" : " openai "
    },
    {
      "id" : " ada " ,
      "object" : " model " ,
      "owned_by" : " openai "
    },
    {
      "id" : " text-davinci-002 " ,
      "object" : " model " ,
      "owned_by" : " openai "
    },
    {
      "id" : " davinci " ,
      "object" : " model " ,
      "owned_by" : " openai "
    },
    ...
  ]
}

要檢索指定模型而不是所有模型的信息，您可以執行以下操作：

 e := openai . New ( os . Getenv ( "OPENAI_KEY" ))
r , err := e . RetrieveModel ( context . Background (), & openai. RetrieveModelOptions {
	ID : openai . ModelDavinci ,
})
if err != nil {
	log . Fatal ( err )
}
