LLMs degrade after 15 turns; new industry tactics emerge
Studies suggest that language models often lose reliability after about 15-20 back-and-forths in a conversation. This may happen because the models must split their attention as the chat gets longer, making it harder to remember or follow earlier instructions. Common problems include forgetting rules, repeating answers, or making up new ones. Researchers and industry teams now use tactics like summarizing conversation history early, breaking tasks into smaller parts, and storing important facts outside the chat to help fight these issues. There is still debate about whether bigger context windows can fix the problem, but most agree that better prompt handling and context management work better than just making context windows larger.
