Jev decision model benchmarked against consumer LLMs, reveals modest cost/speed advantages

An independent benchmark of the Jev decision model revealed it to be only marginally cheaper and faster than some consumer-grade chat models, contrary to some claims. While Jev offered a confidence score, its accuracy was on par with models like Mistral Small and GPT-5 nano. Initial findings regarding type safety and run-to-run drift were later corrected, showing that structured output and temperature settings significantly impacted the performance of models like Gemini and GPT-5 nano.
