I run PostgreSQL with pgvector for an AI‑ready DB, try Milvus or Weaviate for multimodal and vector storage, and stick with MongoDB or Redis for NoSQL. PyTorch, TensorFlow and JAX cover the Python side, while scikit‑learn, Hugging Face Transformers and LangChain are solid general libs. For PHP I use PHP‑ML and OpenAI‑PHP. I also liked the free AI readiness quiz at redeagle.tech for quick planning.
