+    Usage
+    Basic Text Generation
+    from transformers import AutoTokenizer, AutoModelForCausalLM
+    # Load model
+    tokenizer = AutoTokenizer.from_pretrained("bekalebendong/pendo-gpt2-medium-teacher")
+    model = AutoModelForCausalLM.from_pretrained("bekalebendong/pendo-gpt2-medium-teacher")
+    # Generate text
+    prompt = "The history of"
+    inputs = tokenizer(prompt, return_tensors="pt")
+    outputs = model.generate(
+        **inputs,
+        max_new_tokens=50,
+        do_sample=True,
+        top_k=50,
+        top_p=0.95,
+        temperature=0.8
+    )
+    print(tokenizer.decode(outputs[0], skip_special_tokens=True))
+    For Knowledge Distillation
+    # Use as teacher model for distillation
+    teacher = AutoModelForCausalLM.from_pretrained("bekalebendong/pendo-gpt2-medium-teacher")
+    teacher.eval()
+    # Freeze teacher parameters
+    for param in teacher.parameters():
+        param.requires_grad = False
+    # Use teacher logits to train student model
+    # (see full distillation code in repository)
+    Intended Use
+    Primary Use Cases
+    1. Knowledge Distillation: Teacher model for training smaller student models
+    2. Text Prediction: Real-time text suggestions in editors
+    3. Text Generation: General-purpose text completion
+    4. Fine-tuning Base: Starting point for domain-specific fine-tuning
+    Deployment Targets
+    - Local applications (desktop/laptop)
+    - Cloud inference APIs
+    - Edge devices (with quantization)
+    Limitations
+    - Domain: Primarily trained on Wikipedia-style text
+    - Recency: Knowledge cutoff depends on WikiText-103 (2016)
+    - Bias: May reflect biases present in Wikipedia
+    - Size: 355M parameters requires ~1.4GB storage (fp16)
+    - Languages: English only
+    Training Process
+    Complete pipeline:
+    1. ✅ Data preparation: WikiText-103 download and preprocessing
+    2. ✅ Critical fixes: Proper train/val split, no data leakage
+    3. ✅ Optimization: H100-specific hyperparameters (bf16, large batches)
+    4. ✅ Training: 3 epochs with cosine LR schedule
+    5. ✅ Validation: Continuous monitoring, best model selection
+    6. ✅ Testing: Generation quality verification
+    No overfitting detected:
+    - Train loss: 2.822
+    - Validation loss: 2.706 (lower than train!)
+    - Healthy generalization ✓
+    Example Outputs
+    Prompt: "The history of"
+    Output 1: "The history of the United States and the world in general
+            is governed by the international law of nations..."
+    Output 2: "The history of the Royal Navy was recorded in the book
+            of 1802, The History of the Royal Navy..."
+    Output 3: "The history of the city has been marred by conflicts
+            and controversies, including the War of..."
+    Prompt: "Machine learning is"
+    Output: "Machine learning is a method of making inferences about
+            the world from data. Computers have a huge variety of
+            data sources..."
+    Ethical Considerations
+    - Bias Mitigation: Model may perpetuate biases from Wikipedia
+    - Fact Accuracy: Generated text should not be assumed factual
+    - Misuse Prevention: Not intended for generating misleading content
+    - Attribution: Generated text should not be presented as human-written
