Open-Weight LLMs Have Caught Up on Accuracy
Open-weight LLMs have now reached accuracy parity with closed models in regulatory and clinical tasks, at significantly lower costs. The ClinReg benchmark showed models like GLM 5.2 and Kimi K3 performing within one standard deviation of top proprietary models like GPT 5.6 Sol, at one-third of the cost. Different models displayed distinct error profiles, highlighting the importance of choosing models based on task-specific requirements rather than just ranking.
