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.

01

Build datasets

Collect, clean, and organize the data your model will learn from.

02

Prototype models

Interactively code, debug, and refine models with on-demand GPUs + ssh.

03

Optimize models

Run hundreds of experiments in parallel to find the best model.

04

Compare models

Compare hundreds of training runs to identify the best model.

05

Pretrain models

Train models from scratch on large IB GPU clusters with large datasets.

06

Post-train models

Specialize pre-trained models to your data and task with RL, sandboxes.

07

Evaluate models

Test accuracy, safety, and reliability before inference.

08

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.”
Niall LyonsNiall LyonsSTAFF DEEP LEARNING RESEARCHER AT INFINEON
“The ability to easily scale from development to testing, to extensive market simulations is a game-changer”
Jonathan MasciJonathan MasciCO-FOUNDER AND CHIEF SCIENTIST AT NNAISENSE
“Suddenly, scaling compute was effortless, live pipelines could be updated in minutes, and shared studios transformed how we collaborate.”
Eric NielsonEric NielsonDIRECTOR OF EXECUTIVE DATA TEAM AT SLALOM
“Speed let's us focus on solving real problems, not getting stuck on re-inventing our own wheels.”
Igor PoletaevIgor PoletaevCHIEF SCIENCE OFFICER AT INWORLD
“Instead of spending two weeks just figuring out how to run a script, people are analyzing data on day one.”
Dr. Matt WhitewayDr. Matt WhitewayRESEARCH SCIENTIST AT COLUMBIA UNIVERSITY
“Setting up a consistent working environment was no longer a challenge. Everyone could see experiments, rerun them, debug issues, and contribute without friction.”
Nithin ParsonNithin ParsonCO-FOUNDER OF RETICULAR AI
“This gives us the ability to easily ingest, classify, and structure multimodal data at scale, lowering cost and widening access.”
