  "account": "This submission tackles the challenge of providing governance and auditing for model substitutions in dynamic LLM gateways. The platform was built for an AI engineer managing multi-agent systems and dynamic routing in production. The key pain point addressed is the lack of visibility into silent model replacements that occur when high-capacity models are downgraded to smaller or cheaper alternatives. This can lead to issues like context window truncation, hallucinations, and compliance violations.\n\nThe solution consists of three main components. First, a zero-latency Python Interceptor SDK called governance-interceptor. This SDK acts as in-memory middleware that hooks into gateway routing decisions, comparing requested models to actual models without adding latency. Second, a high-throughput FastAPI cloud tracker that handles ingestion of events and computes capability downgrade percentages. Third, a capability risk assessor engine that assigns risk ratings to situations involving model downgrades. Additionally, the system verifies agent provider whitelists and generates compliance audit reports.\n\nThe platform includes a live web dashboard that can be accessed at model-substitution-governance-event.vercel.app. This dashboard features a try demo modal that allows users to simulate gateway substitutions and view real-time risk scoring, context delta computations, and whitelist policy alerts. The entire backend, frontend, and interceptor SDK code is open source on GitHub at Rithika-Gurusamy/Model-Substitutions-Governance-Platform.",
