Still proves nothing either way, anon. Trying the same string on other model and getting a positive result just means that they can "decode" THAT ONE STRING. It doesn't necessarily mean that it can decode b64.
To show that they can, you need to try other b64 strings. Ideally, something that wouldn't be easy to train on (b64 of some sha512 of some random file in your drive) and without access to tools. If it decodes them all, then I'm willing to believe that it can decode b64. I'm even willing to say that it can decode b64 if it only works on some but sometimes fails. But if it can only decode THAT ONE STRING, it cannot decode b64. It just knows what that string means.
