Model Router
Set routing policies for quality, cost, or balanced performance. Siesta AI evaluates each task and routes it to the most suitable model, while keeping governance, deployment, and regional controls aligned with your Azure environment.
Model availability follows Microsoft Foundry Model Router support. Routing mode and selected model subset determine which models are eligible for each request.
Quality mode
Prioritize stronger reasoning models for complex analysis, coding, and high-stakes work.
Cost mode
Route routine prompts to faster, more efficient models to keep spend under control.
Balanced mode
Use a default policy that balances quality, latency, and cost for everyday work.
