OpenAI accused Elon Musk of orchestrating a legal ambush by abruptly changing his lawsuit objectives weeks before the trial. The company filed court documents labeling the recent amendments as legally improper and factually unsupported.

Musk originally sued OpenAI for allegedly abandoning its non-profit mission to pursue profits through a partnership with Microsoft. OpenAI claims the new amendments shift the legal focus to disrupt the proceedings.

The defense argues these changes require different evidence and witnesses than those prepared for the original case. OpenAI maintains the move aims to complicate the upcoming trial.
