Description

Helios is a user interface application built as part of a head-to-head benchmarking experiment to compare the coding and design capabilities of OpenAI's GPT-5.6 Sol and Anthropic's Claude 3.7 Fable 5. It serves as a capability demonstration for building functional, modern UIs using one-shot or minimal-step AI prompting.
