In LLM applications, observability is more critical than in traditional backends, because failures often are not thrown exceptions but the model quietly doing the wrong thing; a complete trace needs at least to record the full input and output tokens of each model call, the parameters and returns of each tool call, the time and token consumption of each step, and the control-flow jump paths.

UnverifiedIf LLM judges that are blind to omissions are widely used for scoring, benchmarking, or guiding model training (e.g., RLHF, RLAIF), the entire optimization loop may be misled, causing models to learn to generate content that appears complete but is actually incomplete.77% similarUnverifiedLLM输出具有非确定性，同一输入在不同时间可能产生不同输出，因此评估流水线常用LLM-as-Judge方法用另一个强大模型评判目标模型输出质量75% similarUnverifiedWhen a node simultaneously performs LLM calls and routing decisions, it leads to repeated evaluation of the same data or multiple LLM calls per step, dragging down token consumption.73% similarUnverifiedModel drift can cause downstream parsing logic in production systems that rely on LLMs to fail silently—no errors are reported but the output deviates from expectations.73% similarUnverifiedLLM inference is stochastic (controlled by the Temperature parameter) and external tool call return values change over time; therefore, perfect deterministic replay requires simultaneously recording all LLM responses and tool return values.73% similar
