Databricks (MosaicML)

MosaicML, now part of Databricks, is an AI training platform that enables enterprises to build and train custom large language models efficiently and cost-effectively. The company developed techniques and tools that dramatically reduce the cost and complexity of training foundation models, making custom LLM development accessible to organizations beyond the largest tech companies.

MosaicML's key innovations include the MPT (MosaicML Pretrained Transformer) series of open-source models and the Composer training library, which implements state-of-the-art training efficiency methods. The platform handles distributed training across hundreds of GPUs, allowing enterprises to train models on their own proprietary data.

Acquired by Databricks for $1.3 billion in 2023, MosaicML's technology is now integrated into the Databricks platform as Mosaic AI, enabling Databricks customers to train, fine-tune, and deploy custom AI models within the lakehouse architecture. This acquisition positioned Databricks as a comprehensive AI platform for enterprises.
