Key Learnings
Designing trustworthy AI requires transparency
Early internal testing revealed that users were skeptical of AI-generated wine recommendations when they didn’t understand the reasoning behind them. To build trust, I introduced clear explanations for each suggestion, showing how factors like flavor notes and user preferences influenced the choices. This experience reinforced that AI must not only be accurate but also explainable to create user confidence.
How I would approach this differently today: CustomGPT
If I were to redo this project now, I would leverage custom GPT models to fine-tune AI responses, ensuring the tone, complexity, and recommendations align with user expectations. This would accelerate iteration cycles and allow for tailor-made responses based on real-time feedback. Additionally, by collaborating more closely with engineers from the start, I could define clear AI behavior and explainability rules upfront, reducing the risk of AI outputs feeling too generic or opaque. This would create a more seamless and trustworthy user experience.
