When we started using DeepSeek AI models in Go, we predicted a simple, dedicated client to simplify our lives. Despite exploring, testing, and customizing several solutions, we found nothing easy, comprehensive, and optimized for Go developers. That's why we created Go-Deepseek, a lightweight but powerful DeepSeek API client for Go.

Go-Deepseek is easy to use, trustworthy, fast, and supports full APIs. You can now easily integrate DeepSeek models into your Go projects with this package, and the great thing is you don't need any programming expertise. And now the question is, how to start, why we built it, and what makes it special?

 

Why Yet Another Go Client?

No dedicated Go client matched our demands. Workarounds were difficult, incomplete, or did not seem right. We decided to design a better Go client that follows idiomatic Go concepts, is easy to install and use, and is optimized for AI-powered apps.

What's Special About Go-Deepseek?

Four things make Go-Deepseek stand out.

The first one is, it's simple. The package structure is clear, with requests under request and replies under response. Everything is as expected.

Second, it's complete. Go-Deepseek supports all DeepSeek API capabilities, so you may utilize the platform without restrictions.

Third, it's reliable. We use several Go tests to discover bugs early and ensure seamless operation.

Finally, it works. Working with AI models requires speed; thus, we have optimized Go-Deepseek to minimize reaction times and retain accuracy.

Installing Go-Deepseek

Now comes the installation phase, to start, all you have to do is run one command:

go get github.com/go-deepseek/deepseek

Get the requirements and install Go-Deepseek in your project. You may now add DeepSeek's AI models to Go apps.

How to Use Go-Deepseek?

Let's see how it works. One way to send a "Hello Deepseek!" message is using DeepSeek-V3 (deepseek-chat) with stream=false.

Basic Usage Example

package main

import (
             "context"
             "fmt"

             "github.com/go-deepseek/deepseek"
             "github.com/go-deepseek/deepseek/request"
)

func main() {
              client, _ := deepseek.NewClient("your_deepseek_api_token")

              chatReq := &request.ChatCompletionsRequest{
                            Model: deepseek.DEEPSEEK_CHAT_MODEL,
                            Stream: false,
                            Messages: []*request.Message{
                                           {
                                                         Role:    "user",
                                                         Content: "Hello Deepseek!", // set your input message
                                           },
                            },
              }

             chatResp, err := client.CallChatCompletionsChat(context.Background(), chatReq)
              if err != nil {
                            fmt.Println("Error =>", err)
                            return
              }
             fmt.Printf("output => %s\n", chatResp.Choices[0].Message.Content)
}

Running the Example Locally

Add the above code piece into your main.go file. Change "your_deepseek_api_token" to a real API token. 

After that, install dependencies and initialize a Go module:

go mod init your_project_name
go get github.com/go-deepseek/deepseek

At last, run the script:

go run main.go

The output will be like this:

output => Hello! How can I assist you today?

Fine-Tuning Go-Deepseek for Your Needs

You can change Go-Deepseek so that AI can engage in more complicated ways.

If you want a more active experience, set Stream: true to turn on streaming mode. An alternative DeepSeek model? Just change the Model parameter. Better error handling comes from keeping track of API problems and dealing with odd cases correctly.

Batch requests speed up the process of handling many messages at once. If you make fewer API calls, your app will run faster and better.

Conclusion

Go-Deepseek started as a necessity but has become powerful, efficient, and Go-friendly. Building chatbots, AI-powered apps, or integrating DeepSeek into processes is easy with this client.
