What Lightning AI is
Lightning AI is an AI development platform from the PyTorch Lightning team. It provides a browser development environment covering prototyping, model training, scaling and deployment, aimed at machine learning engineers, researchers and AI product teams.
What you can do with it
- Develop AI projects in the browser
- Train and scale models
- Deploy an AI service
- Avoid local environment configuration
Who it is for
- ML engineers and researchers
- AI startup teams
- Students and developers wanting cloud GPUs
What to watch out for
- GPU quotas, collaboration features, deployment methods and cost need checking before committing
- Cloud training cost accumulates quickly with large experiments
- Data and model artefacts live on the platform unless you self-manage
- Local dependencies still need managing inside projects
Pros & cons
✓ What we like
