OpenAI has raised $6.6 billion in its latest funding round, valuing the company at $157 billion.
The funding will be used to further strengthen OpenAI's leadership in AI research and develop tools for solving complex problems.
Existing investors were joined by SoftBank and Nvidia, while Apple decided not to invest.
OpenAI is considering a transition from a nonprofit to a for-profit model, and the restructuring could result in CEO Sam Altman receiving $150 billion in equity.
