Hermes + AGNT
Open-source agent router — stream outputs into AGNT's heartbeat and fleet layer.
Official sourceWhat it is
Hermes is an open-source, model-agnostic agent router with strong function-calling support. It classifies intents, routes between models and tools, and handles the orchestration layer that sits between a user message and a model response.
Hermes's sweet spot is mixed-model fleets: local models for cheap classification, frontier models for deep reasoning. This is the same pattern AGNT's fleet v2 runs — different implementation, same philosophy.
Where AGNT fits
- Hermes routing output maps cleanly onto AGNT's heartbeat stream. Every Hermes decision (classified intent, chosen model, tool invocation) becomes a heartbeat event, replayable in AGNT's supervisor UI.
- AGNT's runtime supervisor can adopt Hermes as a routing adapter — the supervisor runs singleton leader election and restarts stuck workers, Hermes decides which model handles each message.
- For builders already running Hermes in production: AGNT's fleet spend cap and backpressure semaphore wrap the entire routing decision. Hermes picks; AGNT enforces the budget envelope.
