Large language models in roleplaying applications often lose character consistency and plot details after a limited number of conversational turns, not due to a lack of memory but because the conversation exceeds the model's context window. Simply increasing the context window size is not a complete solution, as it incurs higher costs and latency, and models tend to perform worse on information buried in the middle of long inputs, a phenomenon known as 'Lost in the Middle'. Effective long-term conversational consistency is achieved through architectural layers like recursive summarization or retrieval-augmented generation, which selectively inject relevant past information into the context window rather than relying on its raw size.
