- How an LLM becomes more coherent as we train it
How an LLM becomes more coherent as we train it — gilesthomas.com · 14h ago · 🤖 AI / ML
This article explores the evolution of output coherence in a transformer-based LLM during training, drawing parallels to Andrej Karpathy’s 2015 RNN observations. The author trained a GPT-2-small-style LLM, featuring 163 million parameters, on approximately 3.2 billion tokens (12.8 GiB of text). The goal was to visually demonstrate the progressive improvement in text generation quality as the model learns. The core takeaway is the observable, gradual emergence of linguistic structure and meaning in the generated text throughout the training process. 💡 Why read it: It provides a concrete, empirical demonstration of how LLM coherence develops over training with specific model parameters and data volume. 🏷️ LLM Training, Model Coherence, Deep Learning, RNNs
