Cut Your AI Bill 75%—Automatically.
Change one URL and Sleipner
routes, caches & compresses every LLM request.No quality loss. Zero engineering lift.
Trusted by teams at scaleups, biotech labs & top Gen-AI startups.
AI Model Costs Are Exploding
Enterprise AI costs quadrupled year-over-year.
Premium models driving unsustainable monthly bills.
Most requests overpay for unnecessary capability.
The answer isn't "use cheap models everywhere"—it's cache semantically, compress smartly, and route intelligently. Sleipner handles all three for you.
How Sleipner Saves You Money
One Line Integration
Add two headers—your Sleipner workspace key and your existing OpenAI / Anthropic / Gemini key. That's it.
Your existing code remains unchanged. Sleipner acts as an intelligent proxy between your application and LLM providers.
Smart Request Analysis
Real-time analysis of token count, complexity & semantic caching opportunities.
Multi-dimensional scoring algorithm + prompt compression detection
Cache & Compress
Semantic prompt caching checks for similar requests; compression reduces token count while preserving meaning.
Vector similarity matching + context-aware compression algorithms
Intelligent Model Routing
Dynamically selects from 15+ models—GPT-3.5 to GPT-4o to Claude Sonnet—choosing the cheapest that meets your requirements.
Dynamic load balancing across providers with real-time performance monitoring
Quality Check & Fallback
Independent judge models grade each answer; if it's < 90, Sleipner escalates automatically.
