Is Sputnik 1 still active?

Hello there, I'm curious about a particular aspect of space history. Could you please clarify for me - is Sputnik 1, the first artificial satellite to be launched into Earth's orbit, still active and functioning to this day? It's a fascinating piece of technological history, and I'm eager to know if it's still up there, transmitting or performing any tasks, decades after its launch. Thanks in advance for your insights!
