When does this happen?

IF Prompt median latency in Langfuse metrics tab is reported as an abnormally high value (e.g., hours instead of seconds) due to the aggregation incorrectly summing observations instead of computing a true median.

How others solved it

THEN Upgrade Langfuse to version 3.86.2 or later, which corrects the median latency calculation. If self-hosted, update the container to the fixed release.
