This is GenomeOcean-bgcFM, a model finetuned on biosynthetic gene clusters (BGC) sequences.  It is built on 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](https://github.com/jgi-genomeocean/genomeocean).

Quick start.

```
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

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