go - Difference between golang pointers

There are 2 kinds of variables that I have. Check for the Go playground, and I don't understand why this is happening. The problem: what I get from the Models it should be a struct to use it for GORM First() function.

The code:

package main

import (
    "fmt"
)

type Test struct {
    Test string
}

var Models = map[string]interface{}{
    "test": newTest(),
}

func main() {
    test1 := Test{}
    fmt.Println("Test 1: ")
    fmt.Printf("%v", test1)
    fmt.Println()
    fmt.Println("Test 1 as pointer: ")
    fmt.Printf("%v", &test1)
    fmt.Println()
    test2 := Models["test"]
    fmt.Println("Test 2: ")
    fmt.Printf("%v", test2)
    fmt.Println()
    fmt.Println("Test 2 as pointer: ")
    fmt.Printf("%v", &test2)

}

func newTest() Test {
    var model Test 
    return model
}
