SemiAnalysis

SemiAnalysis's new GDPx benchmark places Google's Gemini 4 Carbon just behind Anthropic's Claude Opus 5.5, at just over $16 per task against about $51. Removing the cybersecurity, biology and alignment domains reshuffles the leaderboard.

SemiAnalysis has launched GDPx, an agentic benchmark spanning 11 high-value domains including chip design, cybersecurity and recursive self-improvement. The best model scores 12%. SemiAnalysis says safety classifiers depressed the overall scores of Opus 5.5 and GPT-6 Astra.
