UnverifiedAn output parser filling in default values when it encounters a malformed response leaves downstream code unable to distinguish whether a field was produced by the model or fabricated by the parser, which is a silent failure mode.74% similarUnverifiedWhen role tokens become misaligned due to abnormal session states, context truncation, or internal cache errors, the model may misread its own generated text as user input74% similarUnverifiedAn exception being stringified and stuffed into the model context is a silent failure mode: the error becomes a line of text, the model reads and reasons about it as data, the run keeps going, and monitoring reads it as healthy.73% similarUnverifiedSmall models are often unstable in tool-call format, producing missing parameters, wrong field names, or mixed natural-language output, which causes parsing failures and task interruption.73% similarUnverifiedA schema without an 'escape hatch' will cause the model to fabricate content in order to satisfy the schema when the input cannot fit it.73% similar
