UnverifiedMost of what goes wrong in LLM features is not in the model itself but in the surrounding code, such as building the messages list, selecting the model ID, parsing JSON, handling an empty choices list, retrying on 429s, and counting tokens.74% similarUnverifiedLLM application failures can be divided into two categories: knowledge access problems (the model cannot retrieve the correct information) and behavioral problems (the model has the information but fails to process it as required).72% similarUnverifiedThree bottom lines for error handling: if the LLM times out, the workflow must fail rather than silently publish an empty summary; retry counts must be capped and after final failure an alert must be sent with the execution link; each run must record the prompt version and model name.71% similarUnverifiedLLMs have a strong tendency toward error tolerance and completion, and when faced with misaligned table data they typically do not report errors but instead produce seemingly reasonable inferences based on the erroneous data.70% similarUnverifiedAt the model stream level, v0.0.94 retries Provider errors received for a model stream that has already started up to 3 times, and final failures are recorded in logs and Langfuse traces.70% similar
