According to Ethan Mollick on Twitter, Anthropic’s Claude Opus 4.7 now generates the strongest TikZ-based “Sparks unicorn” to date, outperforming prior attempts even without deliberate chain-of-thought, and performing exceptionally when it does reason (source: Ethan Mollick, Twitter, Apr 16, 2026). As reported by Mollick, the unicorn is rendered in TikZ—a LaTeX diagram language not intended for free-form artwork—mirroring the original Sparks of AGI evaluation where a model’s ability to draw a primitive unicorn signaled emergent capabilities (source: Ethan Mollick, Twitter; Microsoft Research, “Sparks of Artificial General Intelligence,” 2023). According to Microsoft Research, the unicorn task probes compositional reasoning and programmatic graphics generation, which are relevant for enterprise automation of technical documentation, scientific figures, and reproducible visualization workflows in LaTeX (source: Microsoft Research, 2023). For businesses, improved TikZ code synthesis suggests near-term productivity gains in scientific publishing, data-heavy reports, and developer tooling where LLMs convert natural language into maintainable vector-graphic code, reducing designer handoff time and enabling version-controlled diagrams at scale (source: Ethan Mollick, Twitter; Microsoft Research, 2023).
