Unified model gateway
Expose one stable API while routing workloads to the best available model for chat, reasoning, coding, summaries, and long-context tasks.
One OpenAI-compatible API to route requests across cost-efficient, high-availability language models — built for teams where cost, uptime, and payment flexibility matter.

SilkRouter abstracts model choice, provider failures, rate limits, and cost differences into a single gateway for developers and enterprises.
Expose one stable API while routing workloads to the best available model for chat, reasoning, coding, summaries, and long-context tasks.
Fail over when a provider is slow, overloaded, over budget, or unavailable. Keep customer applications running through complex network conditions.
Use prepaid credits, hard caps, per-key limits, and usage exports so teams can adopt AI without surprise bills.
Authentication, quota checks, model selection, provider fallback, billing events, request IDs, and abuse controls.
Keep provider details behind the gateway. Customers choose outcomes; SilkRouter handles model selection and availability.
