Validate activity before betting a new project on myvision. - Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge. - Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate. ## Common questions ### What is the difference between pytorch-lightning and myvision? pytorch-lightning: Pretrain, finetune ANY AI model of ANY size on 1 or 10,000+ GPUs with zero code changes.. myvision: Computer vision based ML training data generation tool :rocket:. See the comparison table for live GitHub stats and shared categories. ### When should I choose pytorch-lightning over myvision? Choose pytorch-lightning over myvision when pytorch-lightning is primarily Python; myvision is JavaScript; License: pytorch-lightning is Apache-2.0, myvision is GPL-3.0; Tags unique to pytorch-lightning: data-science, deep-learning, artificial-intelligence, machine-learning. ### When should I choose myvision over pytorch-lightning?
