Abstract

Generative pre-trained models have achieved remarkable success in various domains such as natural language processing and computer vision. Specifically, the combination of large-scale diverse datasets and pre-trained transformers has emerged as a promising approach for developing foundation models. Drawing parallels between linguistic constructs and cellular biology — where texts comprise words, similarly, cells are defined by genes — our study probes the applicability of foundation models to advance cellular biology and genetics research. Utilizing the burgeoning single-cell sequencing data, we have pioneered the construction of a foundation model for single-cell biology, scGPT, which is based on generative pre-trained transformer across a repository of over 33 million cells. Our findings illustrate that scGPT, a generative pre-trained transformer, effectively distills critical biological insights concerning genes and cells. Through the further adaptation of transfer learning, scGPT can be optimized to achieve superior performance across diverse downstream applications. This includes tasks such as cell-type annotation, multi-batch integration, multi-omic integration, genetic perturbation prediction, and gene network inference. The scGPT codebase is publicly available at https://github.com/bowang-lab/scGPT .

  • Empirical benchmarking studies have documented substantial performance degradation for biological foundation models under cross-platform transfer, preprocessing variability, and rare-population evaluation.

    “Empirical benchmarking studies have documented substantial performance degradation for biological foundation models under cross-platform transfer, preprocessing variability, and rare-population evaluation [20–24].”

    From The next paradigm in bioinformatics: a review of multi-agent systems and foundational models for end-to-end scientific discovery (2026) · cites this paper as [20]

    Section 2.2 reports lower annotation precision for rare cell types with extremely few cells in the reference set, supporting the rare-population part of the claim. The Methods discuss batch effects and preprocessing, but the passages found do not document substantial performance degradation caused by cross-platform transfer or preprocessing variability. Page metadata was not available for the decisive section. (LLM, conf=0.86)

  • Perturbation prediction offers experimentally generated model input/output with well-defined objectives, making it a more robust benchmark for assessing foundation models than tasks such as cell annotation and batch correction.

    “Compared to tasks such as cell annotation and batch correction, perturbation prediction offers experimentally generated model input/output with well-defined objectives, making it a more robust benchmark for assessing foundation models (15, 20, 21).”

    From A systematic comparison of single-cell perturbation response prediction models (2026) · cites this paper as [15]

    Methods §4.5 describes control cells as inputs and experimentally perturbed cells as targets; §4.7 specifies metrics for evaluating predictions against measured expression. These passages support the claim that perturbation prediction has defined inputs, outputs and objectives, but the paper does not say it is a more robust foundation-model benchmark than cell annotation or batch correction. Page numbers were not supplied for these passages. (LLM, conf=0.83)

    Experimental — accuracy not yet measured
  • Geneformer and scGPT offer pretrained weights and have been trained using unsupervised objectives on extensive datasets (ca. 30M single-cell transcriptomes).

    “We chose these models because they offer pretrained weights and have been trained using unsupervised objectives on extensive datasets (ca. 30M single-cell transcriptomes).”

    From Zero-shot evaluation reveals limitations of single-cell foundation models (2025) · cites this paper as [7]

    The Results (section 2.1, p. 3) state that scGPT was trained in a self-supervised manner on 33 million single-cell RNA-seq profiles, consistent with the approximate figure. The Supplementary Notes describe Geneformer as a pretrained transformer, but do not establish its training objective, dataset size, or availability of weights. The paper says scGPT's codebase is public, but the cited passages do not explicitly say its pretrained weights are offered. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • scGPT directly learns a cell embedding, which is integrated into its pretraining loss of predicting masked genes: scGPT first predicts a masked gene expression bin and a cell embedding from unmasked genes; then, in a second step, it further iteratively refines masked gene expression using the cell embedding predicted in the first step.

    “However, scGPT directly learns a cell embedding, which is integrated into its pretraining loss of predicting masked genes: scGPT first predicts a masked gene expression bin and a cell embedding from unmasked genes; then, in a second step, it further iteratively refines masked gene expression using the cell embedding predicted in the first step.”

  • Recent advances incorporating graph-based methods and foundational models have improved generalizability.

    “Recent advances have incorporated graph-based methods and foundational models that take advantage of prior knowledge of gene expression relationships, resulting in improved generalizability (14–17).”

    From A systematic comparison of single-cell perturbation response prediction models (2026) · cites this paper as [15]

    The Discussion (p. 17) says scGPT is a pretrained foundation model that generalizes, captures gene networks, and improves downstream performance through transfer learning. Results §2.5 (p. 12) says it learns gene–gene relationships from expression data, but does not describe incorporating a graph-based method or supplying those relationships as prior knowledge. This source supports the foundation-model and generalizability parts, not that more specific account of how the improvement was achieved. (LLM, conf=0.83)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
