Leading AI search agents like GPT-5.4 and Kimi K2.6 don't appear to do much actual research on established benchmarks. They mostly just use the web to confirm what they already learned during training. Researchers at the Harbin Institute of Technology found this using a new time-based benchmark called LiveBrowseComp, which only asks about events from the last 90 days. Once the models can't fall back on memory, performance falls apart and the existing rankings get reshuffled.
