Hermes 4 Technical Report
We present Hermes 4, a family of hybrid reasoning models that combine
structured, multi-turn reasoning with broad instruction-following ability. We
describe the challenges encountered during data curation, synthesis, training,
and evaluation, and outline the solutions employed to address these challenges
at scale. We comprehensively evaluate across mathematical reasoning, coding,
knowledge, comprehension, and alignment benchmarks, and we report both
quantitative performance and qualitative behavioral analysis. To support open
research, all model weights are published publicly at
