The article discusses the problem of "silent model swaps" where LLM providers may change the underlying model without notifying users, leading to unexpected changes in response characteristics. Standard monitoring tools, which only check for HTTP status codes and latency, fail to detect this drift. The proposed solution is to use a "contract validation" approach, such as CorrectoverEngine, which includes an "Identity" dimension to verify that the returned model matches the requested one and uses behavioral fingerprinting to flag inconsistencies. This multi-dimensional validation can also detect other issues like provider outages, system role incompatibilities, and semantic drift. AI
