GenomeOcean-4B

This is the base model of GenomeOcean-4B. It is trained with Causal Language Modeling (CLM) and uses a BPE tokenizer with 4096 tokens. It supports a maximum sequence length of 10240 tokens (~50kbp).

Please see our official implementation on our Github.

Quick start.

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

tokenizer = AutoTokenizer.from_pretrained(
    "pGenomeOcean/GenomeOcean-4B",
    trust_remote_code=True,
    padding_side="left",
)
model = AutoModelForCausalLM.from_pretrained(
    "pGenomeOcean/GenomeOcean-4B",
    trust_remote_code=True,
    torch_dtype=torch.bfloat16, 
    attn_implementation="flash_attention_2",
).to("cuda")
