This library provides Go clients for OpenAI API. We support:
- ChatGPT
- GPT-3, GPT-4
- DALL·E 2
- Whisper
Installation:
go get github.com/sashabaranov/go-openai
ChatGPT example usage:
package main
import (
"context"
"fmt"
openai "github.com/sashabaranov/go-openai"
)
func main() {
client := openai.NewClient("your token")
resp, err := client.CreateChatCompletion(
context.Background(),
openai.ChatCompletionRequest{
Model: openai.GPT3Dot5Turbo,
Messages: []openai.ChatCompletionMessage{
{
Role: openai.ChatMessageRoleUser,
Content: "Hello!",
},
},
},
)
if err != nil {
fmt.Printf("ChatCompletion error: %v\n", err)
return
}
fmt.Println(resp.Choices[0].Message.Content)
}Other examples:
GPT-3 completion
package main
import (
"context"
"fmt"
openai "github.com/sashabaranov/go-openai"
)
func main() {
c := openai.NewClient("your token")
ctx := context.Background()
req := openai.CompletionRequest{
Model: openai.GPT3Ada,
MaxTokens: 5,
Prompt: "Lorem ipsum",
}
resp, err := c.CreateCompletion(ctx, req)
if err != nil {
fmt.Printf("Completion error: %v\n", err)
return
}
fmt.Println(resp.Choices[0].Text)
}GPT-3 streaming completion
package main
import (
"errors"
"context"
"fmt"
"io"
openai "github.com/sashabaranov/go-openai"
)
func main() {
c := openai.NewClient("your token")
ctx := context.Background()
req := openai.CompletionRequest{
Model: openai.GPT3Ada,
MaxTokens: 5,
Prompt: "Lorem ipsum",
Stream: true,
}
stream, err := c.CreateCompletionStream(ctx, req)
if err != nil {
fmt.Printf("CompletionStream error: %v\n", err)
return
}
defer stream.Close()
for {
response, err := stream.Recv()
if errors.Is(err, io.EOF) {
fmt.Println("Stream finished")
return
}
if err != nil {
fmt.Printf("Stream error: %v\n", err)
return
}
fmt.Printf("Stream response: %v\n", response)
}
}Audio Speech-To-Text
package main
import (
"context"

)
func main() {
c := openai.NewClient("your token")
ctx := context.Background()
req := openai.AudioRequest{
Model: openai.Whisper1,
FilePath: "recording.mp3",
}
resp, err := c.CreateTranscription(ctx, req)
if err != nil {

}Configuring proxy
config := openai.DefaultConfig("token")
proxyUrl, err := url.Parse("http://localhost:{port}")
if err != nil {
panic(err)
}
transport := &http.Transport{
Proxy: http.ProxyURL(proxyUrl),
}
config.HTTPClient = &http.Client{
Transport: transport,
}
c := openai.NewClientWithConfig(config)See also: https://pkg.go.dev/github.com/sashabaranov/go-openai#ClientConfig
