Episode notes
Build Design Blocks First
- Design core building blocks (layouts, diagrams, themes) before applying AI to them.
- Invest in taste and templates so AI can generate consistently great visual outputs.
Data-Driven Model Choice
- Gamma runs heavy A/B testing across models and UX because creative quality lacks universal benchmarks.
- They measure user ratings, edits, sharing, and conversion to pick the best model for a task.
Prioritize Prompt Engineering
- Favor prompt engineering and orchestration over fine-tuning for creative visual outputs.
- Test prompts and reuse cross-model strategies for portability and consistent UX.
