+# DeepSpeed
+
+[DeepSpeed](https://github.com/deepspeedai/DeepSpeed), powered by Zero Redundancy Optimizer (ZeRO), is an optimization library for training and fitting very large models onto a GPU. It is available in several ZeRO stages, where each stage progressively saves more GPU memory by partitioning the optimizer state, gradients, parameters, and enabling offloading to a CPU or NVMe. DeepSpeed is integrated with the [`Trainer`] class and most of the setup is automatically taken care of for you.
+
+However, if you want to use DeepSpeed without the [`Trainer`], Transformers provides a [`HfDeepSpeedConfig`] class.
+
+<Tip>
+
+Learn more about using DeepSpeed with [`Trainer`] in the [DeepSpeed](../deepspeed) guide.
