Microsoft today announced that it’s extending its partnership with OpenAI, the startup behind art- and text-generating AI systems like ChatGPT, DALL-E 2 and GPT-3, with a “multi-year, multi-billion-dollar” investment. OpenAI says that the infusion of new capital — the exact amount of which wasn’t disclosed — will be used to continue its independent research and develop AI that’s “safe, useful and powerful.”

OpenAI will remain a capped-profit company as a part of the deal. Under the model, backers’ returns are limited to 100 times their investment — or possibly less in the future.
