■ AI-SUMMARIZED FROM 3 SOURCES ▸ TIMELINE

OpenAI filed a court response alleging that Elon Musk improperly amended his lawsuit against the company with claims that are legally improper and factually unsupported.

In a court filing, OpenAI challenged recent amendments Musk made to his legal case against the startup, characterizing the moves as a sudden tactical shift without proper justification. OpenAI characterized the amendments as a "legal ambush," suggesting Musk changed direction on what remedies he's seeking in the dispute. The company argued the new claims lack legal merit and factual basis. Musk filed his original lawsuit against OpenAI in 2024, claiming the organization had abandoned its nonprofit mission by prioritizing profit under its partnership with Microsoft. The case has centered on OpenAI's corporate structure and governance. The filing marks the latest escalation in the dispute between Musk and OpenAI, which he co-founded in 2015 but left the board in 2018. Both parties have made competing legal arguments about the company's direction and obligations. Courts will need to rule on whether Musk's amendments meet procedural requirements for modification of existing complaints.
