OpenAI's journey from a small nonprofit to a major competitor has been fraught with tension with its longtime partner, Microsoft. Emails from the Musk v. Altman trial reveal that in 2018, Microsoft executives were skeptical of pouring more resources into OpenAI, fearing it might end up in Amazon's hands.

The emails paint a picture of a tech giant struggling to decide whether to support or compete with its own AI offspring. In one instance, Nadella was warned not to take a 'complete bath' by shelling out huge sums for cloud services.

Microsoft’s reservations were echoed across the board: some saw no value in supporting OpenAI while others feared PR backlash from not backing it. The eventual $1 billion investment came almost two years later, after OpenAI shifted towards a for-profit model that promised returns of up to $20 billion.

This story is a reminder that even tech giants can be hesitant when it comes to bold AI projects—especially if they might end up competing with their own subsidiaries. As the race for AI supremacy heats up, such internal battles may become more common.
