I am trying to use openai-go SDK . i tried running simple example mentioned in docs https://developers.openai.com/api/docs/quickstart?language=golang#install-the-openai-sdk-and-run-an-api-call and it didn't run .

cmd/aicli/main.go:36:59: undefined: openai.ResponseNewParams

• my code

package main

import (
	"context"
	"fmt"

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

func main() {
	client := openai.NewClient(
		option.WithAPIKey("OPENAI_API_KEY"),
	)

	resp, err := client.Responses.New(context.TODO(), openai.ResponseNewParams{
		Model: "gpt-5.2",
		Input: responses.ResponseNewParamsInputUnion{OfString: openai.String("Say this is a test")},
	})
	if err != nil {
		panic(err.Error())
