Anthropic’s recent launch of Claude Fable 5.2 on November 9, 2026, drives current trader focus on the highest Claude score achievable on Humanity’s Last Exam (HLE) this year. The new model tops multiple HLE variants, including an 80.2% result on the refined 1,000-question HLE-Diamond subset (Artificial Analysis) and 74.2% on the full 2,500-question exam with tools, outpacing prior Claude Opus 5.5 and Fable 5.1 releases as well as leading Gemini 4 and GPT-6 configurations. These gains reflect Anthropic’s accelerated 1.9× benchmark progress since late 2025, aided by AI-assisted research and larger context windows. Key remaining catalysts include any additional 2026 model drops, HLE-Rolling updates, or independent year-end evaluations that could push Claude scores higher before December 31.
