An indie hacker has developed a cost-effective LLM evaluation system for solo developers, costing approximately £0.20 per run. This system utilizes a small golden dataset of 50-100 input-output pairs from production logs, a judge prompt designed to score responses on accuracy, tone, and format, and a CI gate to block merges if performance degrades significantly. The author suggests using GPT-4o-mini for both the model under test and the judge LLM to minimize costs, estimating that this DIY approach is significantly cheaper than enterprise solutions. AI
IMPACT Enables solo developers to implement robust LLM evaluation, reducing costs and improving product quality.
RANK_REASON The article describes a novel, low-cost method for LLM evaluation, akin to a research paper or technical guide. [lever_c_demoted from research: ic=1 ai=1.0]
