Please Note: This was trained for 4 hours and cost $30, Chat-GPT4 was trained for 6 months, and cost $63 million.


This AI generator leverages a transformer architecture inspired by GPT-2 to produce responses. I developed it as a proof of concept, trained on 2MB of text exclusively from Stack Overflow contributions. Without using a pretrained model or fine-tuning, the model completed 9 epochs of training over 4 hours on an Azure VM equipped with an A100 GPU. The training achieved a final loss of 0.0082, reflecting a strong ability to replicate patterns in the limited dataset.
