Your own sovereign AI lab.
Build frontier models and agents that learn from experience. Use reinforcement learning to improve how they reason, use tools, and complete tasks. Train and serve through one API, on UrbanXI Cloud or your GPUs.
01Develop & Train
The next era of AI. Intelligence you own. Build models and agents around your domain expertise. Reinforcement learning turns experience into better capabilities: agents attempt tasks, you score the outcomes, and the model learns from that feedback.
Supervised Fine-Tuning
Teach your domain using your data, expert examples, and demonstration trajectories. UrbanXI curates the pipeline that gets one approved input onto the review screen.
Reinforcement Learning
Train agents to reason, use tools, and complete multi-step tasks with your own environments and reward functions. LoRA adapters, custom losses, and sampling updates included.
Production Inference
Put the intelligence you build to use. Turn a trained checkpoint into a model deployment. Stream responses through UrbanXI's Python client or an OpenAI-compatible endpoint.
02Own the Stack
Your models are a strategic asset. Build and run them where you choose — with control over your data, your weights, and your compute.
UrbanXI Cloud
The complete AI lab, ready to use. Focus on your models while UrbanXI operates the infrastructure. Managed training, sampling, and inference. Usage-based, per-token pricing.
On-Prem · Your Infrastructure
Turn the GPUs you already own into a frontier AI lab. Deploy the same UrbanXI product in your environment. Your data and model weights stay in your environment.
One API, Everywhere
The same API, workflows, and Console — whether you run on UrbanXI Cloud or your own cluster. From experiment to deployment with a single client.
03Control the Learning
From experiment to deployment. Create a training run, explore your next algorithm, and turn a checkpoint into a deployed model.
01 Train
Distributed training from Python. Choose an open model, configure its adapters, and start learning from your data. UrbanXI handles the compute behind each training step.
02 Improve
Reinforcement learning for better agents. Score rollouts, feed rewards back, and watch reasoning and tool use improve across iterations.
03 Deploy
Save inference weights and publish them under a model name your applications can use. Named deployments, streaming responses, and a familiar API.

04Start Building
Everything you need to get started. Explore the models, inspect the code, and choose your starting point.
