AI benchmarking platform Artificial Analysis has launched version 5 of its Intelligence Index, introducing majority private datasets to evaluate leading frontier and open-weight models. The updated benchmark minimizes test set contamination and provides updated performance evaluations across reasoning, coding, and problem-solving metrics. In the latest rankings, OpenAI models registered gains, while other models like Muse Wonder and Kimi saw drops under the refreshed testing methodology. The index continues to serve as a key independent evaluation standard for enterprise buyers and AI researchers tracking model performance shifts across iterations.
