Cut AI costs
by 70%.
Zero code changes.
Kyrion sits between your app and every AI provider. It routes each prompt to the cheapest capable model, caches repeated queries, and auto-fails over. Change one URL. That's it.

How it works
Three steps.
One line changed.
Your app sends a request
Point your OpenAI SDK at api.kyrion.dev. One URL change. Nothing else in your codebase moves.
Kyrion scores complexity
Semantic analysis scores the prompt 0–1. Simple queries go to Groq. Complex ones to Claude. Identical ones return from cache instantly.
Response delivered cheaper
Your app receives a fully OpenAI-compatible response. Same format. Same streaming. Just 70% less expensive on average.
Features
Built for production.
From day one.
Semantic Routing
Every prompt is scored 0–1 for complexity. "What is 2+2?" costs fractions of a cent via Groq. "Write me a distributed systems design doc" goes to Claude 3.5. You pay exactly what each query is worth.
Circuit Breaker
Auto-failover between providers. OpenAI down? Requests reroute to Anthropic in milliseconds.
Drop-in replacement
Change 2 lines. Your OpenAI SDK works untouched. No migrations, no rewrites.
+ api.kyrion.dev/v1
Redis cache
Identical queries served in under 2ms at $0.00 cost. 52% average hit rate.
Encrypted vault
Provider keys stored AES-256 encrypted. Never exposed to your application layer.
Real-time analytics
Per-request routing, savings breakdown, and cache performance — live in your dashboard.
Power features
What nobody
else has.
Prompt Alchemy
Bad input in, expert output out. Kyrion intercepts every prompt and runs it through a micro-model that transforms it into structured, professional instructions — before it ever touches GPT-4.
47%
better output quality*
Act as a senior copywriter with 10 years of e-commerce experience. Write a high-converting promotional email for a 25–35 year old audience announcing a shoe sale. Use the AIDA framework: • Attention — bold subject line with urgency • Interest — lifestyle angle, not just price • Desire — social proof + limited stock signal • Action — single clear CTA button Tone: energetic, confident, not pushy. Length: 150–200 words.
* Based on blind evaluation across 1,200 prompt pairs. Measured by output relevance score.
Arena Mode
Stop guessing which AI is best for your use case. Send one prompt to all three models simultaneously, compare results side by side, and let your team pick the winner. Kyrion remembers and routes accordingly.
