Mol-Llama-3.1-8B-Instruct

[Project Page] [Paper] [GitHub]

This repo contains the weights of Mol-LLaMA including the LoRA weights and projectors, based on meta-llama/Llama-3.1-8B-Instruct.

Architecture

1. Molecular encoders: Pretrained 2D encoder (MoleculeSTM) and 3D encoder (Uni-Mol)
2. Blending Module: Combining complementary information from 2D and 3D encoders via cross-attention
3. Q-Former: Embed molecular representations into query tokens based on SciBERT
4. LoRA: Adapters for fine-tuning LLMs

Training Dataset

Mol-LLaMA is trained on Mol-LLaMA-Instruct, to learn the fundamental characteristics of molecules with the reasoning ability and explanbility.

How to Use

Please check out the exemplar code for inference in the Github repo.
