Real-world insights from FineWeb, DCLM, The Stack v2, and modern LLM training

When people talk about training language models, the conversation often jumps straight to architecture choices or training techniques. But here’s the reality: you can have the most elegant transformer architecture and perfectly tuned hyperparameters, but if your training data is messy, biased, or poorly sourced, you’re building on quicksand.
