This article proposes a standardized method for evaluating free AI coding assistant tiers, emphasizing the need for a fixed test set and repeatable metrics over marketing screenshots. It suggests using a dataset of 20 tasks derived from real commit history, categorized into bug fixes, features, and test writing, to ensure models haven't seen the prompts during training. The proposed metrics focus on median performance (pass@k, tokens per passing task, wall time) rather than the best-case scenario, with a particular emphasis on token burn rate for failed attempts to accurately assess cost-effectiveness.
