Spend one or three weeks in Barcelona learning how AI is changing real business decisions. GBSB Global offers two English-taught tracks: AI for Your Future for participants new to AI, and AI in Business for students or professionals already using AI tools. Sessions combine ChatGPT, Claude and Gemini with prompt design, no-code automation, AI agents, responsible AI and the EU AI Act. Small international cohorts work on practical team projects and visit a Barcelona technology company. Mornings are classroom-focused, while afternoons and weekends leave room to experience the city and connect with classmates. Tuition includes teaching, materials, company visits, cultural activities and a certificate; accommodation and travel are separate. The 2027 schedule and fees will be confirmed before enrollment opens.
