Generative AI For All

MosaicML enables you to easily train and deploy large AI models on your data, in your secure environment.

Build your next model.

Trusted by ML Experts

Finally, a large model stack that just works

Train and serve large AI models at scale with a single command. Point to your S3 bucket and go. We handle the rest — orchestration, efficiency, node failures, infrastructure. Simple and scalable.

Stay on the cutting edge with our latest recipes,  techniques, and foundation models. Developed and rigorously tested by our research team.

“Using the MosaicML platform, we were able to train and deploy our Ghostwriter 2.7B LLM for code generation with our own data within a week and achieve leading results.”
Amjad Masad, CEO, Replit

Deploy securely, run anywhere

With a few simple steps, deploy inside your private cloud. Your data and models never leave your firewalls. Start in one cloud, continue on another — without skipping a beat.

Your model, your weights

Own the model that's trained on your own data. Introspect and better explain the model decisions. Filter the content and data based on your business needs.

“In a highly regulated environment, model and data ownership is critical to building more explainable and better models.”
Grace Z.
Director, Fortune 500 Insurance Company

Plug and play

Seamlessly integrate with your existing data pipelines, experiment trackers, and other tools. We are fully interoperable, cloud agnostic, and enterprise proven.

Iterate faster

Run more experiments in less time with our world-leading efficiency optimizations. We’ve solved the hard engineering, systems, and research problems for you. Train and deploy with confidence that no performance was left behind.

"I thought it would take a long time to compress and upload our data, but with MosaicML we did it in minutes. It was amazing. MosaicML breaks down the barriers so we can focus on what’s important."
John Mullan, CTO, Natural Synthetics

Build your way

Choose just the pieces you need from our modular training stack. Modify our starter code however you want. Our unopinionated tools make it easier, not harder, to implement your ideas.
