Review notes

Context from the listing review and editorial research.

Lightning AI evolved from open-source PyTorch Lightning into a full AI cloud platform. Free tier is genuinely generous (~80 GPU hours). Pro at $20/mo annual is competitive for individual researchers. Teams tier targets research labs. Enterprise BYOC is the key differentiator for companies with existing cloud commits. 350K+ users cited on site. Phone verification required to prevent abuse on free tier.
