Briefings

Research indicates that retained history from earlier problem-solving can either improve or degrade later-turn accuracy in large language models. By using controlled replay to isolate internal state changes, the study found that these changes preserve similar relationships across different problem histories. The proposed STAIR method, which freezes the base model and trains only 12,288 parameters to redirect queries from a fixed bank of earlier responses, improved average later-turn accuracy by up to 11.67 percentage points across three Qwen models and four benchmarks.

Key points

• STAIR improves average later-turn accuracy by up to 11.67 percentage points over the unmodified model with history across three Qwen models and four benchmarks.
• Retained history from earlier problems can raise or lower later-turn accuracy within the same domain, depending on specific problem-history pairings.

Context and limitations

The study relies on controlled replay experiments to isolate internal state changes, and results may vary across different problem histories and model configurations.
