We route intelligently using YOUR keys
Real Test: 96.8% Cost Reduction
Every request analyzed. Every dollar optimized. Here's the proof.
Query: "Explain what an API is"
96.8% Saved
Three Strategies. One Result.
42 requests analyzed with the same prompt. Three different optimization strategies tested. All saved massively vs GPT-4o baseline.
Routed to open-mistral-nemo • $0.000005/request
Routed to mistral-large • $0.000206/request
Routed to llama-3.3-70b (groq) • $0.000059/request
Similar queries return instantly at near-zero cost
Baseline: $0.041 (GPT-4o) • Best result: $0.0013 • You save: $0.0397 per request

Four Routing Strategies Working Together
Right model. Right cost. Every time.
Complexity
Scores prompts 0.0-1.0 using length, keywords & patterns. Simple queries → budget models, complex reasoning → flagship models
Task Detection
Identifies task type—coding, creative, analysis, math, translation—and routes to models with matching capabilities
Cost Optimization
Selects the cheapest model that meets complexity & task requirements. No overpaying for simple queries
Performance
Real-time health tracking with circuit breakers, P95 latency monitoring, and automatic failover
Cost intelligence, not cost cutting
Drop-in replacement for OpenAI SDK. Just change the base URL and let intelligence take over.
Intelligent Routing
Three routing strategies (cost, semantic, performance) analyze every request and pick the optimal model automatically.
Learn moreSemantic Caching
AI-powered caching understands query intent. "What is ML?" and "Explain machine learning" return cached results.
Learn moreCost Tracking
Track and attribute LLM costs to customers, users, projects, or teams. Perfect for SaaS billing.
Learn moreAutomatic Failover
Seamless fallback between providers. Never miss a request due to rate limits or outages.
Learn moreBudget Controls
Set limits per API key. Get alerts before overages. Prove ROI to finance with predictive forecasting.

Watch Savings Grow
Intelligence kicks in immediately. Track savings in real-time.
import OpenAI from 'openai';
// Just change the baseURL - intelligence takes over
const client = new OpenAI({
apiKey: 'YOUR_COSTBASE_API_KEY',
baseURL: 'https://api.costbase.ai/v1',
});
// Set model: "auto" for intelligent routing
const response = await client.chat.completions.create({
model: 'auto', // We pick the optimal model
messages: [{ role: 'user', content: 'Explain quantum computing' }],
optimize: 'cost', // Cost, quality, or speed
});
// Response includes cost transparency
console.log(response.costbase);

Stop Overpaying for LLM APIs
Most teams overpay because they use expensive models for every query, can't cache effectively, and have no visibility into spend.
Costbase fixes all of this. Choose your deployment.
