For teams spending $15K+ / month on LLM APIs

Smarter LLM Routing.
Stop Overpaying.
Guarantee Quality.

Sending every request to GPT-4o is the #1 cost mistake. A FAQ lookup and a legal analysis shouldn't cost the same. With Casca, your simple requests cost 97% less — complex ones stay on the best model.

Cost Optimization

Four systems working together: classify complexity, protect quality, cache answers, and learn automatically.

◈

Complexity-Aware Routing

Every prompt is classified as HIGH, MED, or LOW in real time. Simple queries route to Gemini Flash (97% cheaper). Critical analysis stays on GPT-4o. No manual rules — our 97-rule engine handles 11 languages natively.

SLA Quality Protection

Legal, compliance, and medical prompts are force-routed to GPT-4o / Claude Sonnet — always. If quality drops below your threshold for 3 consecutive days, you get a full refund. Written in the contract, not a promise.

Semantic Caching

"What is an API?" gets asked 200 times a day. Same question, same answer, zero cost. Our global knowledge cache matches semantically — typos, rephrasing, multilingual variants all hit cache at $0.

Auto-Learn Flywheel

Ambiguous prompts ("幫我搞定", "fix it") enter the AMBIG queue for review. Every resolution trains the engine. Your savings compound monthly — clients see 15-25% improvement in routing accuracy over 6 months.
