Usage

from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

# Load model and tokenizer
tokenizer = AutoTokenizer.from_pretrained("your-username/lex-fridman-chatbot")
model = AutoModelForCausalLM.from_pretrained("your-username/lex-fridman-chatbot")

# Generate response
def chat_with_lex(question):
    prompt = f"Human: {question}\n\nLex:"
    inputs = tokenizer.encode(prompt, return_tensors="pt")
    
    with torch.no_grad():
        outputs = model.generate(
            inputs,
            max_length=inputs.shape[1] + 100,
            temperature=0.8,
            do_sample=True,
            top_p=0.9,
            pad_token_id=tokenizer.eos_token_id
        )
    
    response = tokenizer.decode(outputs[0], skip_special_tokens=True)
    return response.split("Lex:")[-1].strip()

# Example usage
response = chat_with_lex("What do you think about artificial intelligence?")
print(response)

Sample Conversations

Human: What do you think about artificial intelligence? Lex: I think it's a big idea that we're seeing in the way computers are becoming self aware.

Human: How do you approach difficult conversations? Lex: You approach them with your hands and you have a conversation with the viewer.

Web Interface

This model comes with a beautiful Streamlit web interface for easy interaction:

Model Architecture

• Architecture: GPT-2 based transformer (DialoGPT)
• Vocabulary Size: 50,257 tokens
• Context Length: 1024 tokens
• Precision: FP16 for efficient inference
• Multi-GPU: Supports distributed inference

Limitations and Biases

• The model is trained on a limited dataset from podcast transcripts
• May reflect biases present in the training data
• Responses are generated based on patterns learned from transcripts
• Not suitable for providing factual information or professional advice
• Best used for casual conversation and entertainment

Ethical Considerations

• This model is for educational and entertainment purposes
• Does not represent the actual views or opinions of Lex Fridman
• Should not be used to impersonate or misrepresent the real person
• Users should be transparent about AI-generated content
