MT-OSC: Path for LLMs that Get Lost in Multi-Turn Conversation

arXiv:2604.08782v3 Announce Type: replace Abstract: Large language models (LLMs) suffer significant performance degradation when user instructions and context are distributed over multiple conversational turns, yet multi-turn (MT) interactions dominate chat interfaces. The routine approach of appending full chat history to prompts rapidly exhausts context windows, leading to increased latency, higher computational costs, and diminishing returns as conversations extend. We introduce MT-OSC, a One-off Sequential Condensation framework that efficiently and automatically condenses chat history in

Why this matters
Why now

The proliferation of LLMs in chat interfaces has made the limitations of context windows and multi-turn conversations a pressing and widely experienced problem.

Why it’s important

Efficiently handling multi-turn conversations is critical for the practical deployment and user experience of large language models, impacting their utility across various applications.

What changes

This framework offers a concrete technical solution to a major bottleneck in sustained, natural language interactions with LLMs, potentially improving performance and reducing operational costs.

Winners
