Train the GPT-2 Model Yourself in Just 90 Minutes for Only $20

Exciting news for AI enthusiasts and developers! Andrej Karpathy has successfully showcased how to reproduce the 124 million parameter GPT-2 model in a mere 90 minutes at a cost of approximately $20, utilizing a powerful cloud setup with an 8x A100 80GB GPU.

Originally released by OpenAI in 2019, the GPT-2 model has garnered significant attention, particularly for being the entry-level version in the series. By renting a GPU instance, Karpathy was able to execute an efficient training process, and he generously provided the complete training script along with visualizations for those interested in replicating the feat.

Key Highlights from Karpathy’s Demonstration:
– Rapid Reproduction: The GPT-2 124M model was trained in just 90 minutes.
– Budget-Friendly: The entire process cost around $20, thanks to an 8x A100 80GB GPU rental.
– Performance Efficiency: With up to 60% peak model FLOPS utilization achieved during training.
– Extensive Training Data: The model was trained on an impressive dataset containing 10 billion tokens sourced from the web, known as the FineWeb dataset.
– Superior Benchmarking: Karpathy’s version outperformed the checkpoint released by OpenAI for the same 124M model.
– Expanded Capabilities: He also managed to reproduce a 350M model within 14 hours for about $200, demonstrating the scalability of his methods.
– Future Prospects: If you’re feeling ambitious, the full 1558M model, which was the state-of-the-art in its time, can be trained within a week for an estimated $2,500.

This opportunity brings Machine Learning models closer to individuals and small teams who wish to experiment and innovate without exorbitant costs. For those who wish to dive deeper, you can find all necessary resources and discussions on his LLM.c/discussions/481″>GitHub page.
