OpenAI GPT-5 Startup HackathonWe’ve harnessed the power of GPT-5 to build smarter, more intuitive chat and tool interactions for our Nutrition Tracking app—giving users personalized guidance that feels like talking to their own dedicated dietitian. Our work leverages GPT-5’s strengths in: • Creativity & Coding – enabling flexible, custom solutions for diverse user needs • Steering & Alignment – ensuring responses stay on-topic and goal-oriented • Health Improvements – providing actionable, evidence-based nutrition advice • Trustworthy Tool Use – delivering reliable and transparent recommendations We pushed the model to its limits—exploring even Generative UI as a stretch goal. The result? A working prototype where users can instantly create custom widgets tailored to whatever they need in the moment, from meal planners to progress trackers.
