Bot repeats itself in long conversations

After 10+ messages, bot starts repeating phrases or giving generic responses like "As I said earlier..." even if the context has changed. In long conversations, the AI Vibe Chat Personality Bot starts repeating the same words and phrases. After several messages, the responses from each personality become predictable and sound almost identical.

Main Goals Ensure the bot generates more diverse responses even during long chats.

Avoid exact or near-identical repetitions of earlier phrases.

Make each vibe (friendly, sarcastic, zen, formal, etc.) feel consistent yet flexible.
