What do OpenAI, Uber, and Instacart have in common? They all use Ray, open-source software built by Anyscale that’s used to scale up AI models. The company, which emerged from a research lab at UC Berkeley, enables users to easily scale Python code and create custom apps without becoming experts in distributed computing. It was founded by Cofounder Robert Nishihara, CTO Philipp Moritz, and executive chairman — and Databricks cofounder — Ion Stoica. The company has raised $259 million and has a valuation of $1.1 billion. Recently, the company announced an update to warn users if Ray was configured to be accessible on the open internet after security researchers found that hackers had installed crypto-miners on some users’ AI servers, as Forbes reported.
