Validate activity before betting a new project on archai. - Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge. ## Common questions ### What is the difference between litgpt and archai? litgpt: High-performance LLMs with recipes for pretraining, finetuning and deployment. archai: Accelerate your Neural Architecture Search (NAS) through fast, reproducible and modular research..
