The Code is designed to help industry comply with the AI Act's rules on general-purpose AI, which will enter into application on 2 August 2025. The rules become enforceable by the AI Office of the Commission one year later as regards new models and two years later as regards existing models.
This "voluntary" tool is only voluntary in that it isnt in effect yet. However, within a year parts of it will be and two years from August 2 it will be. Mind you there are growing calls from EU countries to have the EU pause its AI Act rollout because of what it will do to not just the AI industry but innovation in Europe as well.
