[gotcha] Retrying or regenerating an AI response produces worse results because the failed attempt pollutes conversation context

When implementing retry/regenerate, remove the previous failed assistant response from the conversation history before re-sending the request. Do not append the retry as a new turn after the failed response. If using a framework, use a sliding window or summary memory that excludes the failed turn.

Journey Context:
The intuitive UX pattern is a 'Regenerate' or 'Try again' button. But under the hood, if the previous bad assistant response remains in the messages array sent to the API, the model sees it as context. It may try to correct it, apologize for it, or be influenced by its content — especially if the previous response was a refusal, where the model may double down on refusing. This is counter-intuitive because in traditional software, retry is stateless. In LLM APIs, every message in the array shapes the next response. The fix is to either remove the failed response from the messages array before the retry call, or maintain a separate display history \(what the user sees\) and API history \(what gets sent\). Many teams learn this only after users report that retrying makes things worse, not better.
