Model Router & Cost Optimizer
Unified multi-model API gateway with intelligent routing to reduce costs, semantic caching to boost performance, and automatic failover for reliability.
Architecture Overview
Core Features
Unified Multi-Model API
One API endpoint to access 50+ models from OpenAI, Anthropic, Google, and open-source providers. Switch without code changes.
Intelligent Policy Routing
Dynamic routing based on cost, latency, and quality. Support A/B testing, canary releases, and on-demand switching.
Semantic Caching
Smart caching based on vector similarity. Similar requests return cached results, saving 30-60% cost.
Automatic Failover
Automatically switch to backup models on failure, ensuring 99.9% availability. Custom fallback chains supported.
Budgets & Limits
Set budget caps by team, project, or user. Real-time cost monitoring with automatic alerts or throttling.
Evals & A/B Testing
Built-in evaluation framework to compare model output quality. Traffic-based A/B testing support.
Code Example
// SkyAIApp Router SDK - Unified API
import { SkyAI } from '@skyaiapp/sdk';
const client = new SkyAI({ apiKey: process.env.SKYAI_API_KEY });
// Single API for all models
const response = await client.chat.completions.create({
model: "auto", // Let router decide based on policy
messages: [{ role: "user", content: "Explain quantum computing" }],
// Routing policy (optional)
routing: {
strategy: "cost-optimized", // or "latency-optimized", "quality-first"
fallback: ["gpt-4o", "claude-3-sonnet", "gemini-pro"],
maxCost: 0.05, // Max cost per request in USD
maxLatency: 3000, // Max latency in ms
},
// Enable caching
cache: {
enabled: true,
ttl: 3600, // 1 hour
similarityThreshold: 0.95,
},
});
console.log(response.choices[0].message.content);
console.log(response.usage); // Includes cost breakdown
console.log(response._routing); // Which model was used and whySupported Models
...and 40+ more models
Use Cases
Cost Optimization
Automatically select the most cost-effective model based on task complexity. Simple tasks use cheaper models, complex ones use premium.
High Availability
Configure multi-model fallback chains so no single model failure affects business. Achieve true 99.9% SLA.
Compliance & Data Residency
Auto-route to compliant endpoints based on user region. European user data stays in Europe.
Progressive Migration
Safely migrate from one model to another with traffic percentage control. Instant rollback supported.

Free tier is enough for testing and small-scale usage. Enterprise customers get dedicated support.
