 * **GSoC is about learning first, delivering second.** We prefer that you take your time and ask for help when contributing to our projects, rather than using AI to quickly write code that may work, but you do not understand. Our midterm and final evaluations of your work will consider how you grew as an open source contributor, in addition to what you created.
