LLM Routing: Multi-Provider Without Lock-In
Route every AI query to the right model based on cost, capability, and content — with an OpenAI-compatible gateway, intelligent routing rules, fallbacks, and per-org provider management.
💡 Output token costs range from $0.14 to $30.00 per million tokens — a 214x differential between the cheapest and most expensive models. Most organizations send every query to their most expensive model.
Organizations use 3-7 different LLM providers — OpenAI, Anthropic, Google, Groq, Fireworks, open-source models. But without a routing layer, every application hardcodes its provider, and switching models means rewriting code.
The Problem with Hardcoded LLM Providers
When each application directly calls an LLM provider's API:
- Switching models requires code changes in every application
- No fallback when a provider goes down or rate-limits you
- No cost optimization — every query goes to the same expensive model regardless of complexity
- No governance — queries bypass your security and compliance rules
- Vendor lock-in — your infrastructure is captive to one provider's pricing and roadmap
How Xilos LLM Routing Works
Xilos provides an OpenAI-compatible API gateway. Your applications call Xilos once, and Xilos routes each query to the right model based on your rules.
Intelligent Routing Rules
Define routing rules that match queries to models based on:
- Keywords and content — Route legal queries to a private enterprise model, marketing content to a cost-efficient model
- User role and department — Different teams get different models
- Cost optimization — Simple queries go to cheap models, complex queries go to frontier models
- Organizational policy — Free-tier users get one model, paid users get another
Automatic Fallbacks
When a provider goes down or returns an error, Xilos automatically falls back to your configured secondary model. Your users never see an outage.
Zero-Code Model Switching
Switching from GPT-5 to Claude Opus to Gemini is a configuration change in the Xilos dashboard — not a code deploy. Your applications don't change at all.
Per-Organization Provider Management
Each Xilos organization manages its own provider credentials (API keys) in an encrypted credential store. Different orgs can use different providers, different models, and different routing rules — all through the same Xilos gateway.
OpenAI-Compatible API
Xilos exposes an OpenAI-compatible /chat/completions endpoint. Any tool that supports OpenAI (TypingMind, LangChain, custom apps, WorkBench) works with Xilos without modification. Just point the base URL at your Xilos instance.
Routing vs. Gateway: What's the Difference?
A gateway is the secure entry point — authentication, rate limiting, logging, compliance. A router sits behind the gateway and makes intelligent model selection. Xilos provides both in one platform.
