SymRouterModel selection and routing
Choose the model that fits the job.
A quick summary and a complex review need different models. SymRouter™ guides you to the best model for your specific task, or picks it for you, with full transparency on response time and estimated cost.
Why it matters
Make the model choice visible, not mysterious.
A quick lookup and a contract review need different models. Sending every request to the same model overspends on simple work or falls short on hard work. SymRouter weighs each task against your performance and cost constraints, picks a suitable model from the options in your workspace and shows the model, response time and estimated cost with every answer.

Model bands
Fast, Balanced or Advanced: a model band for every priority.
SymAI Ask™ groups its available model options into three bands. Choose a band or an individual model from the options available in your workspace, or leave it to SymRouter™ to select the best model for you.
Fast
Models that answer quickly, for routine questions and lookups.
Balanced
Models that balance depth and speed, for everyday work.
Advanced
The most capable models in your workspace, for demanding questions and reviews.
Review another response
Change the model. Continue the work.
SymAI Ask can regenerate a response with another available model, so the first model choice is never final. Compare the new result against the task and its sources, then continue the work.
See what answered
Every answer shows its model, time and estimated cost.
The response metadata shows the model used, the response time and an estimated cost. Review that information alongside the answer.
| What to inspect | What it helps you understand |
|---|---|
| Model used | Which available option produced the response |
| Response time | How long that response took |
| Estimated cost | The displayed usage estimate, not your final invoice |
| Answer and citations | Whether the response supports the work you need to do |
Routing in workflows
Route each workflow step to the model that fits it.
SymRouter brings model selection into agentic workflows. Each step can be routed on the task, the quality required, the acceptable wait and the processing constraints, so a workflow is not bound to one provider by default. Routing options are confirmed for each implementation.
- Task fit
- What the step needs to accomplish.
- Quality
- The standard a useful result must meet.
- Latency and cost
- The wait and the spend that suit the work.
- Control
- The providers and processing arrangements you permit.

SymRouter and SymModels
SymModels supplies the models. SymRouter picks the right one.
- SymModelsSymModels™ is the model layer: which options are available and where they fit.
- SymRouterSymRouter is the selection layer: how the model is chosen for the work.
- SymContextSymContext™ supplies the business material the model needs, and it stays in place when you change the model.
FAQs
Questions teams ask about SymRouter.
No. Fast, Balanced and Advanced group model choices. Brief, Standard and Deep Research are separate controls for General responses in SymAI Ask.
No. Automatic selection within a band is not a guarantee of the best result for every task. Validate the output and confirm the routing behaviour available in your workspace.
Discuss the requirement with our team and explore the possibilities.
No. Models can differ in output and tool behaviour. Important use cases need evaluation before a new option becomes the default.
