AI要約ペイロードでテキストが不可解に反転する

バグ
1

私の要約のほとんどが失敗しています。LLMに送信されるテキストの一部が逆になっているためです（！）投稿が単に次のようになっている場合：

This post is to test whether sections of text get reversed in the payload sent to the AI endpoint.

実際にLLMに送信されるテキストは次のとおりです。

This post is to test whether sections of text get .tniopdne IA eht ot tnes daolyap eht ni desrever

この単純なテストでは、文字列のちょうど真ん中で折り返されるか、反転します。

これが狂っているように聞こえることは承知していますが、スクリーンショットと、ai_api_audit_logsからの対応する raw_request_payload を示します。

興味深いことに、Sonnet は、逆さまのテキストが難読化またはルール回避の試みであると見なすため、多くのトピックの要約を拒否します。

私は 3.6.0.beta3-latest で最新の状態です。
