Hi! I had the same question while going through the lessons. From what I understand, the AI Automation CTO custom GPT may have been renamed, made private, or replaced since the video was recorded. You could try searching the GPT Store for ‘AI Automation’ or ‘CTO’ to see if a newer version appears. If you still can’t find it, it might be worth asking Liam directly in the community or checking the course updates and pinned posts for an updated link. Hope that helps, and please share if you find the answer!
