Opus crushes the nacre fan task and extracts signal from DeepSeek's attempts, comparison shows

A comparison of Claude Opus, Astra, and DeepSeek on the nacre fan rendering task finds Opus vastly superior; Astra can compete, DeepSeek cannot.

The more interesting observation: Opus is good at extracting signal from DeepSeek's work — after seeing DeepSeek's few-turn attempts, Opus's output beats its own zero-shot result. Three videos illustrate: Opus after seeing DeepSeek, DeepSeek (few turns), and Opus zero-shot.
