Rockset was a real-time analytics database founded by ex-Facebook engineers behind RocksDB. It raised $100M+ from Sequoia, Greylock, and Icon, targeting low-latency vector and full-text search for production apps. OpenAI announced the acquisition in June 2024 to power retrieval inside its products. Rockset wound down customer service on September 30, 2024 and migrated technology and team into OpenAI's infrastructure org.

MosaicML built tools for training large language and diffusion models efficiently on commodity GPUs, releasing the MPT-7B and MPT-30B open-source models in 2023. Databricks acquired the company in July 2023 for roughly $1.3B, folding MosaicML's stack into the Databricks platform as the basis for what later became DBRX and the Mosaic AI training service. The standalone MosaicML brand was retired; the team and tech continue inside Databricks.
