Somebody give Andrej some H100s already
**OpenAI**'s GPT-2 sparked controversy five years ago for being "too dangerous to release." Now, with **FineWeb** and **llm.c**, a tiny GPT-2 model can be trained in **90 minutes** for **$20** using **8xA100** GPUs, with the full 1.6B model estimated to take **1 week** and **$2.5k**. The project is notable for its heavy use of **CUDA** (75.8%) aiming to simplify the training stack. Meanwhile, a Twitter debate between **Yann LeCun** and **Elon Musk** highlighted the importance of **convolutional neural networks (CNNs)** in real-time image processing for autonomous driving, with LeCun emphasizing scientific research's role in technological progress. LeCun also criticized AI doomsday scenarios, arguing for cautious optimism about AI safety and regulation.
