Projects

Every project is getting its own live demo. Some are ready to explore now, with the rest on the way.

PromptRouter Engine

checking

LLM routing gateway dispatching queries across a 5-tier model matrix with pre-execution adversarial guardrails. Evaluated on 700 RouterBench and LMSYS queries, achieving an estimated 84.06% cost reduction vs. flagship, neutralizing 56.78% of prompt injection attempts with zero false alarms.
