Models overview
How Ethen surfaces and routes models — the Model Library catalog, local runtimes, and the Gateway model list.
Ethen gives you three ways to discover and use models: the Model Library catalog, local model runtimes, and the Gateway model list. Which one you reach for depends on whether you are browsing, running locally, or integrating via API.
Model Library
The Model Library is the central catalog of models available through Ethen. Use it to browse models by provider, compare context windows, modalities, and pricing signals, and open a model profile for deeper detail.
See the Model Library overview for a full guide.
Local models
Local runtimes let you run open-weight models on your own machine through Ollama or LM Studio. Models loaded locally are available in the Console for chat and in the Code workspace.
See Local versus hosted models for the trade-offs and setup guide.
Gateway model list
The Gateway exposes a /api/gateway/v1/models endpoint that returns the subset of models available for API routing. This is a different surface from the full Model Library — only models with active provider routes appear here.
See the Gateway overview for how routing and model availability work in the API.
Choosing a model
Start from the task, not the model. Match the workload to the smallest model that reliably meets quality and latency needs, then route with fallback for resilience.
See Choosing a model for detailed guidance.
