Developer proposes invariant scoring for LLMs to catch silent code errors

By PulseAugur Editorial · [1 sources] ·

A developer has proposed a new method for evaluating Large Language Models (LLMs) that focuses on scoring "invariants" rather than just code completions. This approach aims to identify subtle errors where code compiles and appears functional but fails to meet critical properties, such as maintaining a correct balance in financial transactions or preserving order while removing duplicates. The developer created a harness that treats LLMs as untrusted interns, running their code against a small set of adversarial test cases to ensure functional correctness and prevent silent bugs from being merged into production code. AI

IMPACT This approach could lead to more robust LLM code generation by focusing on functional correctness over superficial compilation.

    I Stopped Scoring Completions. I Started Scoring Invariants.

    <p>The cheapest completion I got this week compiled on the first try and still stole money from a fake ledger. That is not a vibe check. That is a failure class, and most "did the model write code?" scoreboards never look for it.</p> <p>If your eval rewards a fenced Python block,…
