Build datasets
Collect, clean, and organize the data your model will learn from.
Build, train and deploy your
own specialized models.
Everything AI teams need to own their AI: guaranteed on-demand GPUs, clusters,
AI coding agents, and enterprise-grade infrastructure.
Trusted by 450,000+ devs and AI teams
Stop renting AI.
Own it instead.
Specialized models outperform general-purpose models. Lightning provides the enterprise-grade tools, expertise, and GPUs to help you own your own AI.
Prototype models
Interactively code, debug, and refine models with on-demand GPUs + ssh.
Optimize models
Run hundreds of experiments in parallel to find the best model.
Compare models
Compare hundreds of training runs to identify the best model.
Pretrain models
Train models from scratch on large IB GPU clusters with large datasets.
Post-train models
Specialize pre-trained models to your data and task with RL, sandboxes.
Evaluate models
Test accuracy, safety, and reliability before inference.
Inference
Run your own AI at scale on our 40,000 GPUs and reduce AI costs.

“We simply wouldn't have had the compute access or the ability to iterate so fast. In these past 4-5 months, we've been able to do 1.5-2 years worth of work.”
“The ability to easily scale from development to testing, to extensive market simulations is a game-changer”
“Suddenly, scaling compute was effortless, live pipelines could be updated in minutes, and shared studios transformed how we collaborate.”
“Speed lets us focus on solving real problems, not getting stuck on re-inventing our own wheels.”
“Instead of spending two weeks just figuring out how to run a script, people are analyzing data on day one.”
“Setting up a consistent working environment was no longer a challenge. Everyone could see experiments, rerun them, debug issues, and contribute without friction.”
“This gives us the ability to easily ingest, classify, and structure multimodal data at scale, lowering cost and widening access.”
