OrcaRouter Debuts Programmable Routing to Cut AI Inference Costs
San Francisco-based OrcaRouter has unveiled Routing DSL, a framework allowing developers to replace static model selection with programmable logic. By defining routing rules through YAML and CEL expressions, engineering teams can now dynamically distribute AI workloads across more than 200 models to balance cost, latency, and performance requirements.

The platform integrates directly into OrcaRouter’s AI Gateway, treating model orchestration as a core component of application infrastructure rather than a secondary configuration. Developers can implement complex strategies, such as routing routine queries to efficient open-source models while reserving expensive frontier-class compute only for prompts that demand higher reasoning capabilities.
Internal testing suggests this approach allows teams to replicate the performance of top-tier models like Claude Fable 5 while significantly lowering overall inference spending. By executing parallel model requests and applying automated guardrails, the system shifts the focus from relying on a single large model to building a specialized, governed intelligence stack. Routing DSL is available immediately for all users via an OpenAI-compatible endpoint.
