🚀 Usage

Using Transformers

from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

# Load model and tokenizer
tokenizer = AutoTokenizer.from_pretrained("nguyennm1024/llamarine")
model = AutoModelForCausalLM.from_pretrained(
    "nguyennm1024/llamarine",
    torch_dtype=torch.bfloat16,
    device_map="auto"
)

# Generate response
prompt = "What is dead reckoning navigation?"
inputs = tokenizer(prompt, return_tensors="pt")
outputs = model.generate(
    **inputs,
    max_new_tokens=200,
    temperature=0.7,
    top_p=0.9,
    do_sample=True
)
response = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(response)

Using vLLM (Recommended for Production)

from vllm import LLM, SamplingParams

# Initialize model
llm = LLM(
    model="nguyennm1024/llamarine",
    tensor_parallel_size=2,  # Adjust based on your GPU setup
    dtype="bfloat16"
)

# Configure sampling
sampling_params = SamplingParams(
    temperature=0.7,
    top_p=0.9,
    max_tokens=200
)

# Generate response
prompt = "How do you anchor a ship in rough weather?"
outputs = llm.generate([prompt], sampling_params)
print(outputs[0].outputs[0].text)

📊 Performance

Response Speed: 15-20 tokens/second (vLLM on 2x A100)
Context Awareness: Maintains conversation history
Maritime Accuracy: Specialized knowledge in nautical operations
Safety Focus: Emphasizes safe maritime practices
