Insider Tips for Prompting with AI

Summary

Prompt specificity is the difference between unusable and production-ready AI outputs. Google's vibe coding expert reveals that adding bullet-point details, referencing specific libraries like Three.js, and iterating with visual references can transform generic outputs into exactly what you envisioned—turning 'make a racing game' into a fully functional, polished product.

Key Takeaways

1. Replace open-ended prompts with bullet-point specificity: instead of 'make a racing game,' specify 'small blue car, round track, finish line, pickupable boost.' This dramatically narrows the output space toward your intended result.
2. Use framework-specific keywords to trigger optimal model behavior—e.g., mention 'Three.js' when building 3D games because models are trained extensively on this popular library, producing better code quality.
3. Upload visual reference images alongside prompts to guide the model visually. Point out specific details you like and explicitly request the model incorporate them—this bridges the gap between your mental vision and AI output.
4. Iterate rapidly post-generation by testing the output, identifying friction points, then returning to the prompt with micro-refinements ('boost faster or last longer'). This back-and-forth loop converges on your exact vision faster than initial perfectionism.
5. Ask the model itself for keyword suggestions before prompting—e.g., 'what are the best web technologies for 3D games?'—to discover framework names and terms that will trigger better outputs without scouring documentation.

Transcript Excerpt

A great prompt is the difference between this and this. Let's go to ai.studio/build. This is our vibe coding product, and it's a great place to build your first app by just describing it. I think some things people miss when they're prompting for the first time is how much you can actually guide the model. If I was to type an open ended prompt like, make me a racing game, here's what I would get. Now let's actually add that specificity. I'm not just saying, hey, make me a racing game. I'm actual...
