Lightning AI ⚡️

The hardest part of open source isn't building features, it's keeping contributors engaged. PyTorch Lightning just crossed 300 million downloads and William Falcon is going to share how to build and scale open-source AI at dAGI Summit 2025 for Open Source AI Week by The Linux…

Pretty cool community-built RL environment on @LightningAI's environments hub for quantum RL... The qrl-qai Playground is a no-code environment where anyone can experiment with quantum RL and visualize how agents learn in quantum space. Pick an environment, run an episode, and…

⚡️ We’re hiring a Data Scientist at Lightning AI! This is a foundational data role that will shape the course of our product road map. You’ll partner with Product and Sales leadership, uncover patterns that drive decisions, and build the data foundations that make those…

Our new @Meta Llama 3.3 70b endpoint is live on Lightning AI ⚡ The team that helped define how the world trains models with PyTorch Lightning is now bringing that same precision to inference. @ArtificialAnlys benchmarked our model and the results landed right where we wanted:…

We launched our first inference endpoint! The same team that redefined training with PyTorch Lightning is now doing the same with inference! Our first benchmarks on Llama 3 (70B) speak for themselves: - 1-2nd fastest time to first token - best cost vs round trip performance -…

You need full environments, not just code, to train Reinforcement learning and agent systems safely. The challenge has been making those setups portable and reproducible. The new Lightning Environment Hub fixes that: portable sandboxes with code, drivers, datasets, and hardware…

I hear everyone's discovering the gap in GPU prices between AWS and the neo clouds 😬? This is one reason we created the @LightningAI GPU marketplace.... to provide pricing much needed pricing transparency and let you choose where you run your work from a single place 😊.

Lighting just saved my experiments. had a deadline and needed to do abalations studies. Scheduling jobs made it easy. Thanks! Also would appreciate a bit more clear documentations on how to schedule and access artifacts. @lightningai lightning.ai

Finally excited to launch the Lightning Environments hub. RL and agents need environments (or sandboxes) to operate in safely. Reproducing, sharing and cloning environments is basically impossible today. Lightning environments hub fixes that by packaging code, drivers,…

⚡ Distribute and Optimize Your PyTorch Models With Zero Code Changes Join Luca Antiga and Thomas Viehmann at PyTorch Conference 2025 for a look at Thunder, a new PyTorch compiler that makes scaling and optimizing models simple and fast. 📅 10/22 | 4:25–4:50 PM | Room 2001–2003…

Stop rebuilding the same workflows. In Lightning AI, you can share a Studio as a template, with your team, or just specific users. Set permissions, copy a link, done. Those with permission can clone it: dependencies, environment, and files included. Browse publicly published…

⚡ PyTorch Conference 2025 is almost here – less than 3 weeks out! Join us for: Accelerating Experimentation + Unlocking Real-Time Inference on Microcontrollers with Lightning Luca Antiga, our CTO & Niall Lyons, Infineon Technologies 10/22 | 11:35–11:45 AM | Room 2018–2020…

It finally happened. ⚡ PyTorch Lightning is now downloaded ~40% more than Keras. Still on Keras? Time to see what Lightning can do → lightning.ai/pytorch-lightn…

It finally happened! I guess PyTorch Lightning is now more downloaded than Keras by ~40% more! If you're still using Keras, you need to try PyTorch Lightning ⚡️⚡️⚡️ lightning.ai/pytorch-lightn…

300M downloads of PyTorch Lightning. That's +300M times builders chose Lightning to train, deploy, and scale their models. Huge thanks to the community, this is your milestone as much as ours. Find out why we're so popular → go.lightning.ai/3WgZoZo

Claude Sonnet 4.5 is now live on Lightning ⚡ Anthropic’s newest coding model ranks at the top of SWE-bench and OSWorld, + a huge leap in reasoning and math (they’re calling it their best yet). Try it out on Lightning and get ~5 million free tokens → lightning.ai/models/anthrop…

Claude sonnet 4.5 is now available via Lightning ⚡️⚡️⚡️ I have not personally verified it, however it looks like a great coding model (they claim it's "their best one yet"). Anyhow, try it out! Through lightning you get ~5 million free tokens lightning.ai/models/anthrop…

Thanks to everyone who came out to our September NYC meetup. With a focus on AI-powered commerce and sales, attendees were treated to presentations from Ethan Henley & Gianni Crivello(Sylow Technologies), Jyoti Shah (ADP) and Lightning AI fellow @JonKrohnLearns. Appreciate all…

Deploying GenAI models doesn’t need to take days. With LitServe, it happens in minutes. Fast setup, flexible configs, and proven performance at scale. You can deploy to cloud, edge, or anywhere in between. Founders and engineers are already using it for: 🧠 Physical AI…

Last Thursday we packed the Lightning HQ penthouse for Retro AI Arcade Night. In just one hour, participants built their own Pac-Man-style games and trained an AI agent to play them. Big thanks to @VoltagePark for teaming up with us, and to everyone who joined and made it such a…
