)

model_id = "meta-llama/Llama-3.3-70B-Instruct"

tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    quantization_config=bnb_config,
    device_map="auto"
)

# Generate
messages = [
    {"role": "system", "content": "You are a helpful coding assistant."},
    {"role": "user", "content": "Write a Python web scraper using BeautifulSoup"}
]

input_ids = tokenizer.apply_chat_template(
    messages,
    return_tensors="pt"
).to("cuda")

outputs = model.generate(
    input_ids,
    max_new_tokens=512,
    temperature=0.7,
    do_sample=True
)

print(tokenizer.decode(outputs[0], skip_special_tokens=True))

Method 4: llama.cpp (CPU+GPU hybrid)

Troubleshooting

Out of Memory

# Use AWQ quantization (most memory efficient)
--model casperhansen/llama-3.3-70b-instruct-awq --quantization awq

# Reduce context length
--max-model-len 8192

# Use tensor parallelism
--tensor-parallel-size 2

Slow First Response

• First request loads model to GPU - wait 30-60 seconds

• Use --enable-prefix-caching for faster subsequent requests

• Pre-warm with dummy request
