OpenAI’s latest GPT-5.6 Sol model currently trails the HLE leaderboard at roughly 49.5% on Artificial Analysis evaluations and around 58% for earlier GPT-5.4 Pro variants, well behind Anthropic’s Claude Opus 5 and Mythos 5 at 64.7% and 64.5%. Rapid 2026 gains have come from expanded reasoning chains, test-time compute scaling, and multimodal refinements that lifted OpenAI from early-year baselines near 20% to the upper 40s–50s, yet competitors have maintained the edge through superior post-training and architectural advances on this expert-level benchmark of graduate knowledge and multi-step reasoning. Additional GPT-5.x releases or early GPT-6 previews before year-end represent the main near-term catalysts that could close the gap, though sustained leadership by Anthropic and Meta on no-tools leaderboards continues to shape trader expectations for OpenAI’s highest 2026 score.

For resolution, “accuracy” refers solely to the value labeled “HLE Accuracy” or a clear equivalent metric if the data’s presentation or terminology is restructured, regardless of the model’s Calibration Error or any other displayed metric.
The resolution source will be the official Humanity’s Last Exam leaderboard at https://agi.safe.ai/. If the resolution source becomes unavailable during the listed timeframe, this market will remain open to allow the relevant data to become available again. If the source remains unavailable after the end of the listed timeframe or is otherwise confirmed to be permanently unavailable, official Humanity’s Last Exam results published elsewhere may be used. If no official alternative source is available, this market will resolve to "No".
