Everyone is talking about AI Engineers, but most beginners still confuse them with ML Engineers. 🤖
ML Engineers train and improve models using datasets, GPUs, neural networks, PyTorch, TensorFlow, Jupyter, and model optimization.
AI Engineers build real AI products using RAG pipelines, vector databases, APIs, agents, guardrails, evals, context windows, LangChain, and LlamaIndex.
ML Engineers build the brain.
AI Engineers build the system around the brain.
