The biggest AI trial ever kicks off

Summary

Elon Musk's $130 billion lawsuit against OpenAI commenced on Tuesday, April 28, 2026, with Musk testifying and accusing CEO Sam Altman of "stealing a charity." OpenAI's legal team countered, labeling the suit as "sour grapes" due to the company's success post-Musk's departure. Concurrently, Google finalized a classified AI deal with the Pentagon, allowing its models for "any lawful government purpose," despite an open letter from over 600 employees protesting military AI use. This follows similar deals by OpenAI and xAI with the Pentagon. Additionally, researchers demonstrated Talkie, a 13B AI model trained exclusively on pre-1931 text, to explore AI reasoning with a historical worldview, notably showing its ability to generalize by writing functional Python code despite the language not existing in its training data.

Key takeaway

For CTOs and AI/ML Directors navigating the complex landscape of AI development and deployment, be aware of the escalating legal and ethical scrutiny facing major AI players. Your teams should carefully review contractual obligations and internal ethical guidelines, especially when engaging with government or defense sectors. The ongoing OpenAI trial and Google's Pentagon deal highlight the critical need for transparency and robust governance frameworks around AI's purpose and use to mitigate significant financial and reputational risks.
