Do Gnostics believe Jesus is God?

I'm curious to understand the stance of Gnostics on the divinity of Jesus. Do they believe that Jesus is God, or do they hold a different view? I'm interested in hearing more about their theological perspective and how it differs from other Christian denominations that affirm the deity of Christ. Could you elaborate on this aspect of Gnostic belief, and perhaps provide some insights into the historical and philosophical roots of their convictions?
