Understand how model routing fits into Ethen.
Gateway docs explain model lanes, routing policies, request visibility, usage awareness, and fallback behavior where configured across apps and workflows. The page explains how to think about route policy, model lanes, usage awareness, and visibility without reducing Gateway to a list of providers. The point is to understand the routing shape before relying on precise implementation detail.
The routing guide for the model workspace.
Gateway docs help builders understand how Ethen routes model work without reducing the product to a provider list. The important concepts are model lanes, route policies, request history, usage awareness, fallback behavior where configured, and the way Gateway connects product and workflow surfaces to model access. Gateway documentation is strongest when it teaches a builder how route decisions should work: why one lane fits a task, how request history stays visible, and where configured fallback belongs in the picture.
- Explain flagship, open, and local model lanes as routing concepts. Lane concepts matter because model choice is a product decision, not only an ops detail.
- Describe routing policies without fixed provider or model counts. Policy concepts help teams route requests more intentionally.
- Show request visibility, usage awareness, and route records. Usage awareness matters because routing often has cost and quality consequences.
- Explain fallback behavior where configured without uptime promises. Fallback should be framed as configured behavior, not as an absolute promise.
- Connect Gateway concepts to API, Status, Evidence, and product workflows. Request visibility matters because routing needs a readable record.
Gateway documentation capabilities
The Gateway docs provide a conceptual map for routing decisions and operational visibility. The goal is a routing mental model that helps teams build cleaner products and calmer operations.
Model lane guide
Explain when a workflow might use flagship, open, or local lanes based on task needs and supported configuration. Route policy concepts help teams align product behavior with workflow needs.
Routing policy concepts
Describe how a product or workflow can select a route by task type, context, review need, or privacy posture. Lane concepts help builders explain quality, speed, and privacy posture choices.
Fallback behavior where configured
Explain how fallback planning can be represented when a route changes because of availability, suitability, or policy. Visibility concepts matter because routing should be reviewable after the call.
Request visibility
Show how request history, status, and route decisions help builders inspect model behavior. Usage awareness matters because cost and volume shape real product decisions.
Usage awareness
Explain usage signals as operational context for model work, not as pricing or billing commitments. Fallback concepts help teams design routes that are resilient without overpromising.
Workflow integration
Show how workflows can use Gateway routing for each step instead of hardcoding model paths. Evidence concepts keep the routing story connected to the surrounding workflow.
How Gateway routing fits together
Gateway docs should make route decisions easy to understand before a product depends on them. Gateway docs should make route reasoning feel practical instead of abstract.
Define the workload
Identify the task category, context sensitivity, workflow step, and expected output. Start with the kind of work the product is trying to route.
Choose the lane
Map the workload to a flagship, open, or local lane based on need and supported configuration. Choose lane and policy concepts that match that work.
Apply the route
The gateway direction describes a shared surface for routing the request. Understand how request and route visibility should appear after the call.
Record the decision
Route, status, usage signal, and fallback notes can become part of the request history. Design configured fallback and review expectations deliberately.
Review and adjust
Teams use status, evidence, and workflow outcomes to improve routing policies over time. Keep implementation certainty separate from conceptual guidance.
Visibility and control
Gateway routing is easier to trust when route decisions are visible and reviewable. Teams trust routing more when they can read the decision path afterward.
Selected lane
Show which lane handled a request where available. Visible route policy helps explain why the system behaved the way it did.
Route reason
Explain routing by task, policy, privacy posture, or workflow need where configured. Lane visibility helps connect a result to the path that produced it.
Fallback note
Record when fallback behavior changes the request path. Usage visibility helps teams adjust policy more responsibly.
Usage signal
Surface usage awareness by route or workflow where data is available. Evidence visibility helps route changes remain reviewable over time.
What this page represents
This page explains Gateway concepts inside Ethen. It covers routing, lanes, request visibility, usage awareness, and configured fallback behavior while exact provider availability and implementation details live in current documentation. The page deliberately avoids claiming exact provider availability or behavior unless another verified source in the repo supports it.
