Current LLM gateways like LiteLLM, Portkey, and TensorZero excel at routing requests to various AI providers, managing retries, and tracking costs. However, they lack the crucial capability to verify the semantic correctness or factual accuracy of the LLM's output. This oversight can lead to silent failures where users receive incorrect or hallucinated information, which is more dangerous than a system error. A new approach, termed 'verified failover,' aims to address this by validating LLM responses across multiple dimensions such as schema compliance, semantic equivalence, and factual consistency before they reach the user, triggering automatic remediation if issues are detected.
