Summary

DAREBench placed 233 tasks into six workload groups and compared 35 commercial and open models over 7,587 runs.

DAREBench adapts tasks from 22 source benchmarks into a two-by-three matrix defined by input modality and execution form. All tasks run in a shared environment with contract-based scoring and evidence audits. Across 23 commercial API models and 12 locally deployed open-weight models, no system dominated all groups. Text and multimodal workloads produced different accuracy-cost trade-offs, while local models were competitive in several groups but trailed frontier commercial systems overall. The benchmark argues that deployment choices should follow workload profiles rather than a single aggregate score; its conclusions remain tied to the selected tasks, environment and reference cost assumptions.
