Multi-Turn Reasoning When Context Arrives in Pieces: Scalable Sharding and Memory-Augmented RL
arXiv:2606.12941v1 Announce Type: new Abstract: When a user reveals task-critical information across several conversation turns, LLM accuracy drops by up to 65% despite full context availability. We show that this Lost in Conversation degradation can be substantially mitigated by training models to maintain a compact rolling memory instead of attending to a growing history. To make such training scalable, we introduce a low-cost sharding pipeline that converts single-turn QA datasets into multi-turn fragmented-information episodes, eliminating the need for hours of manual annotation.

The proliferation of complex AI interactions and multi-turn conversations makes memory management a critical, emergent challenge for LLM reliability and practical application.
This research addresses a fundamental limitation in large language models (LLMs) which currently hinders their effective deployment in dynamic, real-world, multi-turn applications.
Current LLM architectures struggling with long contexts and multi-turn reasoning may evolve to incorporate more efficient rolling memory mechanisms, improving accuracy and reducing computational overhead.

- · Conversational AI platforms
- · Customer service automation
- · LLM-powered enterprise tools
- · LLMs reliant solely on increasing context windows
- · Applications requiring extensive manual annotation for multi-turn training
LLMs will become significantly more reliable and accurate in multi-turn interactions, reducing errors and improving user experience.
The ability to train models for complex, fragmented information tasks more cheaply will accelerate the development and deployment of sophisticated AI agents.
Improved multi-turn reasoning could enable AI to handle more nuanced and complex real-world workflows, potentially collapsing more specialized white-collar tasks.
