Usage

Using vLLM

python

from vllm import LLM, SamplingParams

# Load the model
llm = LLM(model="ThomasYn/GenomeOcean-4B-GGUF")

# Generate sequences
prompts = ["ATG", "GCA"]
sampling_params = SamplingParams(temperature=0.7, top_p=0.95, max_tokens=100)
outputs = llm.generate(prompts, sampling_params)

for output in outputs:
    print(f"Generated: {output.outputs[0].text}")

Using go-infer (GenomeOcean CLI)

bash

# Scoring sequences
python -m genomeocean.cli score --model_dir ThomasYn/GenomeOcean-4B-GGUF --sequence_file data.txt

# Generating sequences
python -m genomeocean.cli generate --model_dir ThomasYn/GenomeOcean-4B-GGUF --num 10 --max_seq_len 512
