MolParser-7M

Anonymous Open Source now

This repo provides the training data and evaluation data for MolParser, proposed in paper “MolParser: End-to-end Visual Recognition of Molecule Structures in the Wild“ (ICCV2025 under review)

MolParser-7M contains nearly 8 million paired image-SMILES data. It should be noted that the caption of image is our extended-SMILES format, which suggested in our paper.

MolParser-Pretrain: More than 7.7M synthetic training data in pretrain_synthetic_7M subset;
MolParser-SFT [WIP]: Nearly 400k samples for fine-tuning stage in sft_real subset. (We are organizing an OCSR competition based on MolParser-7M, so we have reserved part of the MolParser-SFT data for the competition. Stay tuned!)
MolParser-Val: A small validation set carefully selected in-the-wild in valid subset. It can be used to quickly valid the model ability during the training process;
WildMol Benchmark: 20k molecule structure images cropped from real patents or paper, test_simple_10k（WildMol-10k）subset and test_markush_10k（WildMol-10k-M）subset;

As the paper is still under review, this data is provided anonymously. More information will be provided after the paper has been accepted.

In the future, we will continue to re-clean this dataset, open-source more data, update model checkpoints, refresh the benchmark results, and release the training code.
