Basic Usage

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model_id = "microsoft/Phi-4"

tokenizer = AutoTokenizer.from_pretrained(model_id, trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype=torch.bfloat16,
    device_map="auto",
    trust_remote_code=True
)

messages = [
    {"role": "system", "content": "You are a helpful AI assistant."},
    {"role": "user", "content": "Explain the difference between TCP and UDP."}
]

inputs = tokenizer.apply_chat_template(
    messages,
    return_tensors="pt",
    add_generation_prompt=True
).to("cuda")

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

response = tokenizer.decode(outputs[0][inputs.shape[1]:], skip_special_tokens=True)
print(response)

Phi-3.5-Vision

For image understanding:

from transformers import AutoModelForCausalLM, AutoProcessor
from PIL import Image
import torch

model_id = "microsoft/Phi-3.5-vision-instruct"

processor = AutoProcessor.from_pretrained(model_id, trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype=torch.bfloat16,
    device_map="auto",
    trust_remote_code=True
)

image = Image.open("diagram.png")

messages = [
    {"role": "user", "content": "<|image_1|>\nDescribe this diagram in detail."}
]

prompt = processor.tokenizer.apply_chat_template(
    messages, tokenize=False, add_generation_prompt=True
)

inputs = processor(prompt, [image], return_tensors="pt").to("cuda")

outputs = model.generate(
    **inputs,
    max_new_tokens=512,
    temperature=0.7
)

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

Math and Reasoning

messages = [
    {"role": "user", "content": """
Solve step by step:
A farmer has chickens and rabbits.
Total heads: 35
Total legs: 94
How many of each animal?
"""}
]

# Phi-4 excels at step-by-step reasoning

Code Generation

messages = [
    {"role": "user", "content": """
Write a Python implementation of binary search tree with:
- Insert
- Search
- Delete
- In-order traversal
Include type hints and docstrings.
"""}
]

Quantized Inference

from transformers import AutoModelForCausalLM, BitsAndBytesConfig
import torch

quantization_config = BitsAndBytesConfig(
    load_in_4bit=True,
    bnb_4bit_compute_dtype=torch.bfloat16
)

model = AutoModelForCausalLM.from_pretrained(
    "microsoft/Phi-4",
    quantization_config=quantization_config,
    device_map="auto",
    trust_remote_code=True
)

Gradio Interface

import gradio as gr
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model_id = "microsoft/Phi-4"
tokenizer = AutoTokenizer.from_pretrained(model_id, trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(
    model_id, torch_dtype=torch.bfloat16, device_map="auto", trust_remote_code=True
)

def chat(message, history, system_prompt, temperature):
    messages = [{"role": "system", "content": system_prompt}]
    for h in history:
        messages.append({"role": "user", "content": h[0]})
        messages.append({"role": "assistant", "content": h[1]})
    messages.append({"role": "user", "content": message})

    inputs = tokenizer.apply_chat_template(messages, return_tensors="pt").to("cuda")
    outputs = model.generate(inputs, max_new_tokens=512, temperature=temperature, do_sample=True)

    return tokenizer.decode(outputs[0][inputs.shape[1]:], skip_special_tokens=True)

demo = gr.ChatInterface(
    fn=chat,
    additional_inputs=[
        gr.Textbox(value="You are a helpful assistant.", label="System"),
        gr.Slider(0.1, 1.5, value=0.7, label="Temperature")
    ],
    title="Phi-4 Chat"
)

demo.launch(server_name="0.0.0.0", server_port=7860)

Phi-4 matches or beats much larger models

Troubleshooting

"trust_remote_code" error

• Add trust_remote_code=True to from_pretrained()

• This is required for Phi models

Repetitive outputs

• Lower temperature (0.3-0.6)

• Add repetition_penalty=1.1

• Use proper chat template

Memory issues

• Phi-4 is efficient but still needs ~8GB for 14B

• Use 4-bit quantization if needed

• Reduce context length

Wrong output format

• Use apply_chat_template() for proper formatting

• Check you're using instruct version, not base
