"And that way, they also don't have to give away their data to someone else."ĭatabricks' move comes at a time when startups are raising millions of dollars of venture capital investment to train their AI models and as big tech firms such as Alphabet's Google (GOOGL.O) and Meta Platforms (META.O) rush to shrink the size and cost of AI models while improving their accuracy. "The future will be that everyone has their own model, and they can actually train it, and they can make it better," Ghodsi said. Ghodsi said the company's researchers had taken a two-year-old model that was freely available and trained it with a small amount of data for three hours on single computer that anyone with a credit card could rent. Ghodsi told Reuters that, while the open-source chatbot displayed impressive capabilities at such tasks as drafting blog posts, the company had not released formal benchmark tests to show that the bot matched ChatGPT's performance.ĭatabricks sells cloud-based data mining and analytics software to businesses and said last year it had surpassed $1 billion in annualized revenue.ĭatabricks wants enterprises to train their own AI models using its software.

The computing costs are "eye-watering", OpenAI CEO Sam Altman has said. OpenAI, valued at $29 billion, trains its AI models with huge troves of data on a supercomputer from investor Microsoft Corp (MSFT.O).
