LLM-WikiRace Benchmark Reveals Frontier AI Models Still Struggle with Planning Over Knowledge Graphs

Researchers introduced LLM-WikiRace, a benchmark to evaluate large language models on planning, reasoning, and world knowledge using Wikipedia hyperlinks. Top models like Gemini-3, GPT-5, and Claude Opus 4.5 achieve superhuman performance on easy tasks but drop sharply on hard difficulty, with Gemini-3 succeeding in only 23% of hard games. The study reveals that world knowledge helps only up to a point; beyond that, planning and long-horizon reasoning are the limiting factors.
