揭开生成性人工智能训练的神秘面纱：从原始数据到推理引擎

Generative AI has evolved from a futuristic concept to a foundational tool for developers and enterprises. While interacting with large language models (LLMs) appears seamless, the engineering behind their creation is intricate and detailed. For developers aiming to build, fine-tune, or comprehend models like GPT-4, Claude, or Gemini, understanding the training pipeline is crucial. The training process consists of several phases, starting from raw, unstructured data and culminating in highly aligned reasoning engines. The first phase is pre-training, which lays the groundwork for subsequent model development.
