I gave Opus 5.5 one prompt and six hours to visualize Invisible Cities (quesma.com)

In a remarkable exploration of AI-powered design capabilities, the author tested two language models, GPT-6 Astra and Claude Opus 5.5, to visualize the imaginative cities described in Italo Calvino's "Invisible Cities." By providing a prompt for a three.js visualization, the author noted significant leaps in the quality of the visuals produced compared to earlier models. Specifically, Claude Opus 5.5 not only completed the task in just 1 hour and 25 minutes (instead of the allocated six hours) but also demonstrated a consistent quality that surpassed expectations, indicating a substantial advancement in AI-assisted design. This experiment highlights the growing potential of AI in creative domains, particularly in generating intricate visualizations and interactive media. The author observed that while early models struggled with coherence and minimalism, newer iterations like Opus 5.5 exhibit remarkable creativity and efficiency. This development opens up new avenues for designers and storytellers, reinforcing the notion that AI could become an invaluable tool in creative processes, prompting users to rethink their roles in interactive media creation as AI technologies continue to evolve.
