The Consistency Quadrant: A Visual Guide to LLM Reliability

AI tools are transforming software and data science, but their non-deterministic nature raises critical questions about their reliability for tasks requiring a single correct answer. Measuring this reliability is difficult because we often lack a "ground truth" to verify the AI's output. A new method called the "Consistency Quadrant" estimates reliability by running a prompt multiple times and comparing the structural variance of the code against the consistency of its execution results. By observing if different code solutions consistently produce the same outcome, we can build confidence in an answer's correctness even without knowing the right solution in advance.
