## Content Summary

Hermes "Mixture of Agents" (MoA) feature:

- **Merge any two (or more) AI models into one virtual model**
- One model runs as **reference**, one as **aggregator**
- Both run **in parallel** per task; aggregator synthesizes final output and handles tool calls
- Virtual model appears as a **single selectable model** in the model picker
- **Results:** 8% above Opus 4.8 solo, 11% above GPT-5.5 solo on hard agentic tasks
- Full Hermes features work **untouched**: Memory, tool use, skills, long sessions, cross-channel messaging
- **Any provider mix works:** OpenAI, Anthropic, OpenRouter, local models

### Community Clarifications

- **@Teknium** clarified: any number of models, not just two — even multiples of the same model
- **Criticism:** increased token costs; @lambdua called it "toy stage"

## Key Points

1. **Architectural approach:** Reference model generates draft responses; aggregator model synthesizes final output from reference + its own reasoning. Tool calls handled by aggregator.
2. **Performance gains:** Double-digit improvements on hard agentic tasks over solo frontier models (Opus 4.8, GPT-5.5)
3. **Transparency:** Virtual model is selectable in picker like any single model — no workflow change needed
4. **Composability:** Any provider combination (OpenAI + Anthropic, OpenRouter + local, etc.)
5. **Scalability:** Not limited to 2 models — N models supported, including same-model multiples (self-fusion pattern)
