Mixture of Agents

Route a hard problem through multiple frontier models in one turn with Mixture of Agents.

MoA is a virtual model provider. Each named preset appears as a selectable model under the moa provider. Reference models run first (no tool schemas, cheap). The aggregator writes the response and makes tool calls. Use /model <preset> --provider moa in the CLI or TUI. The Dashboard and Desktop app show a Mixture of Agents provider row with your preset names. /moa is a one-shot shortcut: it runs one prompt through the default preset, then restores your previous model. Configure presets with hermes moa configure. The default preset uses gpt-5.5 as a reference and claude-opus-4.8 as the aggregator. On HermesBench, a two-model MoA preset scores 0.8202, beating opus-4.8 alone (0.7607) by ~6 points.
