Key differences
- Trainium is rentable as EC2 Trn1/Trn2 instances and Trn3 UltraServers (GA Dec 2, 2025, up to 144 Trainium3 chips), and through SageMaker HyperPod. You program it with the Neuron SDK (native PyTorch).
- Maia 200 (announced Jan 26, 2026) is in Azure US Central (US West 3 next), serves models such as OpenAI GPT on Foundry, and offers a Maia SDK preview. There are no Maia VM SKUs.
- On Azure, the practical alternative for training is ND-series NVIDIA or AMD MI300X VMs.
