New LALA benchmark: 236 humanities questions suggest more post-training can make LLMs dumber

JasonBotterill · x · 2026-10-28

The Literature and Linguistics Analysis Benchmark (LALA) poses 236 open-ended questions on linguistics, logic and literature written by professors at top universities to gauge how close LLMs get to human-like linguistic competence. Its headline finding: linguistic competence is not cumulative—sometimes more post-training makes a model less intelligent, which the authors argue rules out general (let alone super-) intelligence from LLMs. The accompanying Sol Assessment chart shows Claude Fable 5 leading at 62.0%, followed by GPT-5.6 Sol (56.0%) and Gemini 3.1 Pro Preview (52.9%), with Gemma 4 31B at 41.6% and base models as low as 7-8%.
