    model=model_id,
    model_kwargs={"torch_dtype": "auto"},
    device_map="cuda",

    {"role": "system", "content": "You are a funny teacher trying to make lectures as interesting as possible and you give real-life examples"},
    {"role": "user", "content": "How to explain gravity to high-school students?"},
]

outputs = pipeline(messages, max_new_tokens=128)
print(outputs[0]["generated_text"][-1])

Download the Model:PythonCopy

from huggingface_hub import snapshot_download

snapshot_download(repo_id="microsoft/phi-4", local_dir="C:\\phi4")

Install Additional Libraries:bashCopy

pip install huggingface-hub
pip install transformers
pip install accelerate

For GPU:bashCopy

pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu118

Live Examples

1. Example 1: Explaining Gravity to High-School Students:
   • Input: "How to explain gravity to high-school students?"
2. Example 2: Solving a Complex Derivative Problem:
   • Input: "Find the first derivative of ln(x^2 + 1)"

Output:plaintextCopy

Feedback: The solution provided is incorrect. The correct first derivative of ln(x^2 + 1) is 2x / (x^2 + 1). Here's the step-by-step reasoning:
1. Apply the chain rule: d/dx [ln(u)] = 1/u * du/dx, where u = x^2 + 1.
2. Compute du/dx: d/dx [x^2 + 1] = 2x.
3. Combine the results: (1 / (x^2 + 1)) * 2x = 2x / (x^2 + 1).

Output:plaintextCopy

{'role': 'assistant', 'content': 'Alright, class, gather around! Today, we\'re diving into the mysterious and mind-bending world of gravity. Now, I know what you\'re thinking: "Gravity? Isn\'t that just why we don\'t float away into space?" Well, yes, but there\'s so much more to it! Let\'s break it down with some real-life examples that\'ll make your heads spin—figuratively, of course, because gravity keeps them attached to your bodies!'}

Optimization Techniques

Performance Tuning

1. Flash Attention 2:pythonmodel = AutoModelForCausalLM.from_pretrained(
attn_implementation="flash_attention_2",
torch_dtype=torch.float16
   )
2. Quantization:bashpython -m transformers.onnx --model=microsoft/Phi-4 --feature=causal-lm --quantize=avx512_vnni
3. Batch Processing:pythonpipeline = transformers.pipeline(
"text-generation",
model=model,
device=0,
batch_size=4,
max_new_tokens=512
)

Troubleshooting

Common Issues & Solutions

1. CUDA Out of Memory:
   • Reduce batch size
   • Enable gradient checkpointing
   • Use 8-bit quantization
2. DLL Load Failures:powershellvcredist --all --quiet --norestart
3. Slow Inference:
   • Enable NVIDIA GPU Boost
   • Disable Windows Defender real-time scanning
   • Set process priority to "High"

Use Case Implementations

Multimodal Processing

python# Image Analysis
image = Image.open("street_view.jpg")
inputs = processor(
text="<|user|><|image_1|>Describe traffic conditions<|end|><|assistant|>",
images=image,
return_tensors="pt"
).to("cuda")

# Audio Transcription
audio, rate = sf.read("meeting_recording.flac")
audio_inputs = processor(
text="<|user|><|audio_1|>Transcribe and summarize<|end|><|assistant|>",
audios=[(audio, rate)],
return_tensors="pt"
).to("cuda")

"zero_optimization": {"stage": 2}
}

Security Considerations

1. Access Control:
   • Enable TLS for Ollama API
   • Implement JWT authentication
   • Use Windows Defender Application Guard
2. Data Sanitization:pythonfrom transformers import AutoTokenizer
   tokenizer = AutoTokenizer.from_pretrained("microsoft/Phi-4")
sanitized_input = tokenizer.sanitize_special_tokens(user_input)

Future-Proofing

1. ONNX Runtime Optimization:bashpython -m onnxruntime.transformers.optimizer --input=phi4.onnx --output=phi4_optimized.onnx
   
2. DirectML Backend:pythontorch.backends.directml.enabled(True)
device = torch.directml.device()
