Every frontier AI lab is building RL environments.
Now you can start with one instead of building from scratch.
Clone our Othello RL environment template and adapt it to your own RL tasks. Evaluate any OpenAI-compatible model, train with verifiable rewards, and iterate from a
25,000 H100s now available for on-demand!

25,000+ owned H100s. Guaranteed on-demand.
Yesterday, we launched Lightning Cloud: infrastructure we own end-to-end, from GPUs and network fabric to the scheduler and development environment.
That means faster provisioning, topology-aware multi-node training, and infrastructure
Lightning Cloud is here.
Guaranteed on-demand H100s for teams training and experimenting with AI at scale.
Most platforms lease GPU capacity. We own the GPUs, the datacenter fabric, the scheduler, and the developer platform, so you get instant H100 access, bare-metal
Today, @LightningAI launched the Lightning Cloud: instant on demand H100s guaranteed for AI teams that are doing serious training and experimentation.
Our platform and infrastructure teams were absolutely cooking on this one.
- Instant H100 availability
- All the tools you
Hermes Agent crossed 140,000 GitHub stars in under three months and is now the most-used agent on OpenRouter.
Built by Nous Research, Hermes focuses on two things agents have historically struggled with: reliability and self-improvement.
It's provider- and model-agnostic, built
Add experiment tracking to your training runs in just two lines of code.
LitLogger automatically captures your metrics, artifacts, commands, and environment so every run is reproducible.
Compare runs side by side, reproduce results, and quickly identify which configuration
Most AI teams don't need another tool.
They need fewer tools.
Here's what building, training, evaluating, and scaling AI looks like when it's all in one platform.
