Prometheus 2.0: new DRACO state of the art

Prometheus 2.0 achieved a reported 77.4 score on the 100-task DRACO agentic deep-research benchmark, with a 95% confidence interval of 74.5 to 80.2, exceeding the prior Zeus 1.0 preset score of 73.4 and Prometheus 1.0’s 69.2. The result also surpasses the 69.0 best score reported in the OpenRouter paper introducing DRACO, as well as several single frontier models evaluated under the same protocol, including Fable-5, GPT-5.5, and Claude Opus 4.8. Built entirely from open-weights models, Prometheus 2.0 is described as a lower-cost fused model panel that performs web research, evaluates primary sources, conducts calculations, and produces cited reports graded against hidden rubrics. Its highest reported domain scores were in law, medicine, general knowledge, and academic tasks, and it is now available through TrustedRouter under the Prometheus 2.0 model identifier and rolling Prometheus alias.
