Enabling Creative Exploration for Vibe Design Agents
Separating design-direction exploration from code generation via structured specifications broadens UI alternatives without destabilizing output.
The paper proposes an inference architecture for vibe design agents that makes design direction an explicit intermediate decision: a Verbalized Sampling-inspired pre-pass proposes structured design specifications with typicality scores, an external selector samples one, and a downstream generator realizes it under fixed settings. Across 168 prompts with 1,255 paired comparisons per temperature, theme sampling broadens selection coverage and screenshot variation, with LLM-judge preferences varying across interventions and prompt complexity. An online experiment with over 300,000 tasks found the code-export increase statistically uncertain, though negative feedback events decreased alongside modest operational costs.
- Explicit design-specification decision separates exploration from implementation
- Avoids crude temperature increases that destabilize syntax-sensitive code
- 168 prompts, 1,255 paired comparisons per temperature per intervention
- Online test with 300k+ tasks showed uncertain export lift, fewer complaints

Vibe design agents turn natural-language briefs into rendered interfaces and frontend code. Yet a useful design agent should do more than produce one valid page: it should help users explore coherent alternatives. Increasing token-level temperature is a blunt solution because it varies aesthetic decisions and syntax-sensitive code at the same time.
