Anthropic’s recent Claude releases, particularly Opus 5.5 in September 2026 and Fable 5.1 variants, have driven current trader sentiment by posting leading HLE scores of 61–67.7% on tool-augmented and verified leaderboards from Artificial Analysis, BenchLM, and related trackers. These results reflect iterative gains in reasoning depth, tool integration, and performance on the 2,500-question expert-level benchmark spanning math, sciences, and multimodal items. Claude models currently outpace OpenAI’s GPT-6 Astra (~54–55%) and Google’s Gemini variants (~57%), though protocol differences (with/without tools, HLE-Diamond subset) create some variance. With three months left in 2026, further Anthropic model updates or reasoning enhancements could push the highest Claude score toward or beyond 65%, while benchmark saturation risks or evaluation shifts remain key uncertainties for higher thresholds.
