Phi-4-o1

Phi-4 o1 [ Chain of Thought Reasoning ]

[Phi-4 O1 finetuned] from Microsoft's Phi-4 is a state-of-the-art open model built upon a blend of synthetic datasets, data from filtered public domain websites, and acquired academic books and Q&A datasets. The goal of this approach is to ensure that small, capable models are trained with high-quality data focused on advanced reasoning.

phi-4 has adopted a robust safety post-training approach. This approach leverages a variety of both open-source and in-house generated synthetic datasets. The overall technique employed to do the safety alignment is a combination of SFT (Supervised Fine-Tuning) and iterative DPO (Direct Preference Optimization), including publicly available datasets focusing on helpfulness and harmlessness as well as various questions and answers targeted at multiple safety categories.

Dataset Info

Phi-4 o1 ft is fine-tuned on a synthetic dataset curated through a pipeline explicitly built for this purpose. The data is primarily based on the Chain of Thought (CoT) or Chain of Continuous Thought (COCONUT) methodologies. This approach ensures that the dataset is rich in reasoning, problem-solving, and step-by-step breakdowns of complex tasks. The model is specifically designed to excel in reasoning, mathematics, and breaking down problems into logical, manageable steps.

Run with Transformers

# pip install accelerate
from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

tokenizer = AutoTokenizer.from_pretrained("prithivMLmods/Phi-4-o1")
model = AutoModelForCausalLM.from_pretrained(
    "prithivMLmods/Phi-4-o1",
    device_map="auto",
    torch_dtype=torch.bfloat16,
)

input_text = "Write me a poem about Machine Learning."
input_ids = tokenizer(input_text, return_tensors="pt").to("cuda")

outputs = model.generate(**input_ids, max_new_tokens=32)
print(tokenizer.decode(outputs[0]))

You can ensure the correct chat template is applied by using tokenizer.apply_chat_template as follows:

messages = [
    {"role": "user", "content": "Write me a poem about Machine Learning."},
]
input_ids = tokenizer.apply_chat_template(messages, return_tensors="pt", return_dict=True).to("cuda")

outputs = model.generate(**input_ids, max_new_tokens=256)
print(tokenizer.decode(outputs[0]))

Limitations

While phi-4 o1 ft is a powerful and versatile model, it has certain limitations that users should be aware of:

1. Bias and Fairness:

   • Despite rigorous training and safety alignment, the model may still exhibit biases present in the training data. Users should critically evaluate outputs, especially in sensitive contexts.

2. Contextual Understanding:

   • The model may occasionally misinterpret complex or ambiguous prompts, leading to inaccurate or irrelevant responses.

3. Real-Time Knowledge:

   • The model's knowledge is limited to the data it was trained on and does not include real-time or post-training updates. It may not be aware of recent events or developments.

4. Safety and Harmlessness:

   • While extensive efforts have been made to align the model with safety guidelines, it may still generate outputs that are inappropriate or harmful in certain contexts. Continuous monitoring and human oversight are recommended.

5. Resource Requirements:

   • Running the model efficiently may require significant computational resources, especially for large-scale or real-time applications.

6. Ethical Considerations:

   • The model should not be used for malicious purposes, such as generating harmful content, misinformation, or spam. Users are responsible for ensuring ethical use.

7. Domain-Specific Limitations:

   • While the model performs well on general-purpose tasks, it may lack depth in highly specialized domains (e.g., medical, legal, or financial fields) without additional fine-tuning.
