The `model-router` is a sophisticated plugin designed for Nous Research Hermes Agent, offering automatic and cost-aware routing of language models based on conversation turns. It intelligently classifies each turn to select the most suitable and cheapest available tier, escalating to higher tiers only when the task requires more complex reasoning or previous attempts fail. The plugin is built around a fixed five-tier system, allowing users to customize the models, labels, emojis, and reasoning modes for each tier while maintaining the structural integrity. It supports both automatic per-turn routing and manual model pinning via commands like `/t1` to `/t5` and `/auto`. Installation is straightforward, involving cloning the repository into the Hermes plugin directory and running an `install.sh` script that handles profile installation, validation, and repair of core Hermes integrations. It also features robust integration with `hermes-webui`, patching the UI and API to provide native tier controls and ensuring accurate routing during streaming. The plugin includes a dynamic auto-escalation mechanism, bumping up tiers after consecutive tool call failures, and a de-escalation feature (though not fully described in the provided text). Configuration is managed through `model_router.yaml`, which allows for detailed customization of classifier models, tier-specific models, and integration paths, with automatic synchronization into other Hermes configuration files and documentation.
