MosaicML

MosaicML is an end-to-end generative AI platform that enables organizations to pretrain, fine-tune, and deploy large language models and other AI models securely within their own cloud or on-premises environments. The platform handles infrastructure orchestration, efficiency optimizations, and node failures, allowing data scientists and developers to focus on model development rather than backend complexity. It offers specialized components including MosaicML Training (for pretraining and fine-tuning), MosaicML Inference (a fully-managed deployment service), and open-source foundation models like MPT-7B and MPT-30B. Acquired by Databricks in 2023 for approximately $1.3 billion, MosaicML emphasizes full model ownership, data privacy, and cost-effective AI training at scale.
