Model training built for production inference
Bring your training scripts. We'll provide the infrastructure.
Own Your Intelligence
Training infra that empowers engineers and researchers to build models that outperform closed-source alternatives.
Train at scale
Run multi-node training jobs with one command. Our infra handles 1T+ models, 10+TB datasets, and 256k sequence lengths.
Fire and forget
Run jobs on-demand; only pay for the compute you use. Don't worry about starting or stopping your environment.
Built for developers
Bring your own custom training scripts or get started instantly with our ready-to-use training recipes.
Everything you need to fine-tune
From data prep to deployment, our infrastructure empowers you to focus on results, not operations.
Train on the latest hardware
Access the latest-generation hardware for ultra-fast training jobs, including H100s, H200s, and B200s.
Ship checkpoints to prod
Deploy your checkpoints to inference with one click and start testing real-world performance.
No limits for large models
Forget single-node training limitations. Train 1T+ models on datasets of any size with the hardware and networking taken care of.
Integrates with everyone
We bring the infra, you bring the integrations: Weights & Biases, Hugging Face, Amazon S3, all plug-and-play via OneInfer Secrets.
Your data on-demand
Cache models, store datasets, and stop wasting time with lengthy downloads or lost progress between training jobs.
Metrics that actually matter
Quickly debug problems like GPU memory or code inefficiencies via SSH or hardware metrics and logs in the UI or CLI.
