Usage

Basic Text Generation

from transformers import AutoTokenizer, AutoModelForCausalLM

# Load model
tokenizer = AutoTokenizer.from_pretrained("bekalebendong/pendo-distilgpt2-wikitext")
model = AutoModelForCausalLM.from_pretrained("bekalebendong/pendo-distilgpt2-wikitext")

# 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 Text Prediction (Pendo Editor)

from transformers import pipeline

# Create prediction pipeline
predictor = pipeline('text-generation', model="bekalebendong/pendo-distilgpt2-wikitext")

# Get next word predictions
text = "Machine learning is"
predictions = predictor(
    text,
    max_new_tokens=1,
    num_return_sequences=5,
    return_full_text=False
)

for pred in predictions:
    print(pred['generated_text'])

Intended Use

Primary Use Cases

1. Text Prediction: Real-time text suggestions in editors
2. Text Generation: General-purpose text completion
3. Fine-tuning Base: Starting point for domain-specific models
4. Research: Educational and research purposes

Deployment Targets

• Local applications (desktop/laptop)
• Cloud inference APIs
• Edge devices (with quantization)

Limitations

• Domain: Primarily trained on Wikipedia-style text
• Recency: Knowledge cutoff at 2016 (based on training data: WikiText-103)
• Bias: May reflect biases present in Wikipedia
• Size: 82M parameters requires storage
• Languages: English only

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
