Lambda Calculus Benchmark for AI — New Evaluation Approach Tests LLM Reasoning Depth (55pts HN)
GitHub Pages / Hacker News (55pts)·low signal
A new benchmark evaluates LLM reasoning using lambda calculus reduction — a fundamentally different approach from standard benchmarks. Tests whether models can perform symbolic computation steps correctly rather than pattern-matching from training data. 55 points, 17 comments on HN. Related research (λ-RLM) shows 8B models with lambda calculus scaffolding outperform 405B models on long-context tasks with 3.1x less latency.
