Add the module with go get github.com/openai/openai-go/v3, then set the base URL and key as client options.

Fig. I, main.go

// go get github.com/openai/openai-go/v3
package main

import (
	"context"
	"fmt"

	"github.com/openai/openai-go/v3"
	"github.com/openai/openai-go/v3/option"
)

func main() {
	client := openai.NewClient(
		option.WithBaseURL("https://api.pollio.ai/v1"),
		option.WithAPIKey("pl-live-..."),
	)
	params := openai.ChatCompletionNewParams{
		Messages: []openai.ChatCompletionMessageParamUnion{
			openai.UserMessage("Hello"),
		},
		Model: "deepseek/deepseek-v4.1-flash",
	}
	completion, err := client.Chat.Completions.New(context.TODO(), params)
	if err != nil {
		panic(err)
	}
	fmt.Println(completion.Choices[0].Message.Content)
}
