Ray, a Unified Distributed Framework for the Modern AI Stack
summary
Ray presents a unified distributed framework that runs data ingestion, preprocessing, training, tuning and serving within one system, exposing only six core API calls and a shared in‑memory object store to avoid double data transfers. Ray AIR, Ray Tune and Ray Serve integrate with TensorFlow, Hugging Face, Optuna and MLflow and scale from laptop to cluster. Real deployments include OpenAI training large models and a cited example where a Google PaLM‑style model needs over 6,000 TPUs, so distribution is mandatory.
