Together AI raised $800 million led by Saudi Aramco's Prosperity7, bringing the company's valuation to $8.3 billion. The funding round brings the open-source AI infrastructure platform's total capital raised to $1.3 billion.

The investment highlights a push by sovereign wealth funds to back the companies building the backend of the artificial intelligence industry. Together AI, founded four years ago, provides cloud-based access to open-weight models for developers and enterprises. The capital provides funds to expand infrastructure and support growing demand for accessible open-source models as frontier labs increasingly restrict distribution of their most advanced systems.
