We benchmarked frontier AI models on realistic security operations (SecOps) tasks using Cotool’s agent harness and the Splunk BOTSv3 dataset. GPT-5 achieved the highest accuracy (63%), while Claude Haiku-4.5 completed tasks the fastest with strong accuracy. GPT-5 variants dominated the performance-cost frontier. These results provide practical guidance for model selection in enterprise SecOps automation.
