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. Snelleman, H. Hoos, and O. E. Gundersen, "The embrace of open science: An analysis of a decade of AI research and 56 800 conference papers," Under Review, 2026..

Reproducibility Variable Result LLM Response
Research Type Experimental We train Prot2Text-V2 on about 250K curated entries from Swiss Prot and evaluate it under low-homology conditions, where test sequences have low similarity with training samples. Our evaluation includes automated metrics, LLM-as-a-judge scoring for semantic fidelity, and expert human assessment, providing a multi-faceted understanding of model quality and robustness.

Pseudocode No The paper includes figures illustrating the model architecture and data flow, and describes the methodology in text and mathematical equations, but does not present any structured pseudocode or algorithm blocks.
Open Source Code Yes The source code for this project is available at https://github.com/Colin FX/Prot2Text-V2/
Open Datasets Yes The dataset used during our experiments was the one proposed by Abdine et al. [2024]. This dataset is a multimodal dataset with 256,690 proteins, filtered originally from Swiss Prot (see Appendix C) [Bairoch and Apweiler, 2000], with their respective corresponding sequence, the predicted structure from Alpha Fold [Jumper et al., 2021], and the textual description. This curated dataset provides aligned sequence, structure, and text modalities, with rigorous filtering and low redundancy across splits, making it better suited for our multimodal learning tasks. Notably, to the best of our knowledge, this is the only publicly available dataset that minimizes protein sequence similarity between training and test sets.
Dataset Splits Yes The resulting split includes 248,312 proteins for training, 4,172 for validation and 4,203 for testing. We use this established split to allow direct comparison with prior work and to asses our model s ability to transfer knowledge beyond close homologs.
Hardware Specification Yes Our model is implemented using Py Torch and trained on a single node with 8 NVIDIA A100 80GB GPUs.
Software Dependencies No The paper mentions 'Py Torch' and 'Adam W optimizer' but does not specify version numbers for these or any other key software components.
Experiment Setup Yes We use the Adam W optimizer [Loshchilov and Hutter, 2017] with ϵ = 1 10 6, β1 = 0.9, and β2 = 0.999. The learning rate starts at 0.0002 and decays to zero following a cosine scheduler, with a warm-up period covering 6% of the total training steps. For the Lo RA adapter, we apply it to the self-attention modules in both the ESM encoder and LLa MA decoder, using a rank of 32 and an α value of 64. Training lasts for 12 epochs in contrastive learning and 24 epochs for supervised fine-tuning. During the contrastive learning stage, the batch size per device is 1024, which is further divided into 8 chunks to accommodate memory constraints. The batch size is set to 4 per GPU, and gradient accumulation is applied every 8 forward passes, resulting in an effective batch size of 256.
