Karpathy: Let's reproduce GPT-2 (1.6B): one 8XH100 node 24h $672 in llm.c

Andrei Karpathy initiated a discussion about reproducing GPT-2 using llm.c on a single 8XH100 node for $672, highlighting the simplicity and efficiency of the process and providing detailed instructions for setting up and training the model.

• Training GPT-2 in llm.c without the Python stack
• Reproduction costs $672 on an 8XH100 node
• Original GPT-2 required an entire team in 2019
• llm.c is still being fine-tuned for stability
• The project succeeds as an educational resource
