Huffington Post founder Arianna Huffington and OpenAI CEO Sam Altman are throwing their weight behind a new venture, Thrive AI Health, that aims to build AI-powered assistant tech to promote healthier lifestyles.

Backed by Huffington’s mental wellness firm Thrive Global and the OpenAI Startup Fund, the early-stage venture fund closely associated with OpenAI, Thrive AI Health will seek to build an “AI health coach” to give personalized advice on sleep, food, fitness, stress management and “connection,” according to a press release issued Monday.
