π¬ Tasks
Molecule description generation
Please give me some details about this molecule: [C][C][C][C][C][C][C][C][C][C][C][C][C][C][C][C][C][C][=Branch1][C][=O][O][C@H1][Branch2][Ring1][=Branch1][C][O][C][=Branch1][C][=O][C][C][C][C][C][C][C][C][C][C][C][C][C][C][C][C][O][P][=Branch1][C][=O][Branch1][C][O][O][C][C@@H1][Branch1][=Branch1][C][=Branch1][C][=O][O][N]
The molecule is a 3-sn-phosphatidyl-L-serine in which the phosphatidyl acyl groups at positions 1 and 2 are specified as stearoyl and arachidonoyl respectively. It is functionally related to an arachidonic acid and an octadecanoic acid.
Description-guided molecule design
Create a molecule with the structure as the one described: The molecule is a primary arylamine in which an amino functional group is substituted for one of the benzene hydrogens. It is a primary arylamine and a member of anilines.

π Demo
As illustrated in our repository, we provide an example to perform generation.
>> python generate.py \
--CLI True \
--protein False\
--load_8bit \
--base_model $BASE_MODEL_PATH \
--lora_weights $FINETUNED_MODEL_PATH \
Please download Llama-2-7b-chat to obtain the pre-training weights of LlamA-2-7b-chat, refine the --base_model
to point towards the location where the model weights are saved.
For model fine-tuned on molecule-oriented instructions, set $FINETUNED_MODEL_PATH
to 'zjunlp/llama2-molinst-molecule-7b'
.
π¨ Limitations
The current state of the model, obtained via instruction tuning, is a preliminary demonstration. Its capacity to handle real-world, production-grade tasks remains limited.
