Lightning AI is an AI development platform offering on-demand GPU instances from T4 to H200, purpose-built for AI researchers and ML engineers. The platform combines cloud GPU access with managed AI Studios (collaborative notebooks), Lightning Apps (production ML pipelines), and Fabric (distributed training). Competitive on-demand pricing across a range of NVIDIA GPUs makes it a practical choice for teams that want GPU compute tightly integrated with an ML development workflow rather than raw infrastructure.
- Managed AI Studios — collaborative GPU notebooks
- Lightning Fabric for distributed training
- T4 to H200 on-demand with transparent pricing
- ML-first platform — compute + workflow in one product
- Strong open-source community (PyTorch Lightning)
- Platform lock-in vs raw GPU clouds
- Smaller GPU catalog than hyperscalers
- Less suitable for pure infrastructure teams
