Notice: The reproducibility variables underlying each score are classified using an automated LLM-based pipeline, validated against a manually labeled dataset. LLM-based classification introduces uncertainty and potential bias; scores should be interpreted as estimates. Full accuracy metrics and methodology are described in Coakley et alK. L. Coakley, T.

Reproducibility Variable Result LLM Response
Research Type Experimental Extensive evaluations show that Pace LLM achieves 6% improvement on Long Benchโ€™s Multi-document QA and 12.5-17.5% performance gains on ๐œ-Bench tasks, while extending measurable context length to 200K tokens in Needle-In-A-Haystack (NIAH) tests.

Pseudocode Yes Algorithm 1 describes the working memory mechanism of Pace LLM, which dynamically enhances current FFN activations using a memory bank. It consists of three key phases: retrieval, enhancement, and memory update.
Open Source Code No All of the code and data used in this study as well as the necessary documentation to run it will be released upon acceptance.
Open Datasets Yes We evaluate Pace LLM on three established long-context benchmarks: Long Bench [2], ๐œ-Bench [46] and Needle-In-A-Haystack (NIAH) [18]. To evaluate the generalization ability of our method beyond long-context tasks, we also evaluate on MMLU [13], which features shorter context lengths.
Dataset Splits Yes We evaluate Pace LLM on three established long-context benchmarks: Long Bench [2], ๐œ-Bench [46] and Needle-In-A-Haystack (NIAH) [18]. To evaluate the generalization ability of our method beyond long-context tasks, we also evaluate on MMLU [13], which features shorter context lengths. We further evaluate on Needle-In-A-Haystack (NIAH) following the official settings [18]
Hardware Specification Yes All experiments are conducted with 4 A100-40G GPUs.
Software Dependencies No The paper mentions using Qwen-2-7B-Instruct [39] and Llama-2-7B-chat [28] as base models, and discusses compatibility with Flash Attention. However, it does not provide specific version numbers for software libraries or dependencies like Python, PyTorch, or TensorFlow.
Experiment Setup Yes Implementation. We apply Pace LLM to Llama-2-7B-chat [28] and Qwen-2-7B-Instruct [39] in training-free and low-cost fine-tuning settings. For low-cost fine-tuning, we follow the setting of Activation Beacon [45]. All experiments are conducted with 4 A100-40G GPUs. In the base setting, the bank capacity M is set to 100, the fusion threshold ฮธhigh is 0.7 and ฮธlow is 0.3, with AMB applied to the 13th and 27th layers.
