Modern Adaptation Handbook: Fine-Tuning Foundation Models 2025
from Steven AI Talk · host Steven
The provided text outlines the 2025 landscape of fine-tuning foundation models, emphasizing a transition from training models from scratch to efficiently adapting pre-existing architectures. It details technical breakthroughs in Parameter-Efficient Fine-Tuning (PEFT), specifically highlighting how methods like LoRA, QLoRA, and DoRA minimize hardware requirements while maintaining high performance. Beyond text, the handbook explores the integration of vision and audio modalities, describing specialized data engineering and architectural connectors for multimodal and speech-to-speech systems. The text also contrasts various alignment strategies, such as DPO and KTO, which refine model behavior through human preference data without the complexity of traditional reinforcement learning. Finally, it serves as a comprehensive guide for practitioners, covering essential software ecosystems, hardware optimization, and the lifecycle of modern model deployment.
