[gotcha] Streaming response stops abruptly mid-generation with no explanation

Handle finish\_reason 'content\_filter' explicitly in your streaming handler. When detected, replace the partial response with a clear, non-judgmental message explaining the response was filtered. Do not display pre-filter partial tokens as the final response.

Journey Context:
Content safety filters can trigger mid-generation after the model has already produced some tokens. The stream ends, finish\_reason returns 'content\_filter', but the partial response before the filter point is already rendered in the UI. Without explicit handling, your UI silently shows an incomplete, potentially confusing response with no explanation. The deeper gotcha: the partial text before the filter may itself be misleading or problematic — it was leading toward filtered content. Showing it without context is worse than showing nothing. Most streaming implementations do not distinguish between normal stream end and filter-triggered end.
