ProteinGLM-3B-CLM

Model Introduction

ProteinGLM-3B-CLM is the open-source version of the latest generative protein language models designed to generate faithful and diverse protein sequences. The ProteinGLM family models are developed by Tsinghua University. Along with this, we have released the int4 quantization ProteinGLM weights and other small models, which include: 1B, 3B, and 10B models trained with masked language modeling for protein understanding, and 1B, 3B, and 7B causal language models aimed at protein design.

Out-of-Distribution Perplexity Evaluation

We evaluated the ProteinGLM-CLM (PGLM) and ProteinGLM-INT4(100B) models on two OOD test sets, one with sequence identity lower than 0.9 with the training set (<0.9 ID) and the other with sequence identity lower than 0.5 with the training set (<0.5 ID). Each OOD dataset comprises approximately 10,000 protein sequences. The perplexity results, compared against ProGen2-xlarge (6.4B), are as follows (lower is better):

Model	ProGen2-xlarge (6.4B)	PGLM (1B)	PGLM (3B)	PGLM (7B)	PGLM-INT4 (100B)
< 0.9 ID	9.7	9.8	9.3	8.9	8.7
< 0.5 ID	14.3	14.0	13.7	13.5	13.3

How to use

python

from transformers import AutoModelForCausalLM, AutoTokenizer, AutoConfig
import torch

tokenizer  = AutoTokenizer.from_pretrained("proteinglm/proteinglm-3b-clm", trust_remote_code=True, use_fast=True)
model = AutoModelForCausalLM.from_pretrained("proteinglm/proteinglm-3b-clm", trust_remote_code=True, torch_dtype=torch.bfloat16)
if torch.cuda.is_available():
    model = model.cuda()
model.eval()

gen_kwargs = {'max_length': 256, 'top_p': 0.8, 'temperature':0.9, "num_beams": 1}
prompt=['', 'MLFVVL', 'LDL', 'VTQA']

for idx, each in enumerate(prompt):
    print(f"Begin generating idx: {idx} with prompt {each}")
    output = model.chat(tokenizer, each, **gen_kwargs)
    print(f"\nEnd generation with length: {len(output.split())} - seqs: {output}\n")
