Elon Musk took the stand on April 29, 2026, in his lawsuit against OpenAI CEO Sam Altman and president Greg Brockman, alleging the company abandoned its nonprofit mission to benefit humanity in favor of profit. Musk, who cofounded OpenAI and invested up to $38 million before the relationship fractured, testified that he founded the company to save humanity, though courtroom observers noted he appeared unprepared and focused heavily on his own accomplishments.
- Musk filed the lawsuit in 2024 accusing OpenAI of abandoning its founding mission to develop AI for humanity's benefit and shifting to profit-focused goals
- Jury selection began April 27; Musk testified as first witness on April 29 in federal court in Oakland
- Musk invested up to $38 million in OpenAI early on; disputes centered on company structure and whether it should merge with Tesla

Researchers led by Nick Levine, David Duvenaud, and Alec Radford released Talkie-1930, a 13B open-weight language model trained exclusively on English text from before 1931, designed to study how language models generalize without knowledge of modern events, technology, or post-1930 history.
- 13B parameter open-weight model trained on pre-1931 English text only
- Led by Nick Levine, David Duvenaud, and Alec Radford
- Released April 28, 2026
- Designed for historical reasoning and generalization research
- Model has no knowledge of internet, smartphones, World War II, or post-1930 events
NVIDIA released Nemotron 3 Nano Omni on April 28, 2026, an open multimodal model that unifies vision, audio, and language capabilities into a single system for AI agents. The model achieves up to 9x efficiency gains by eliminating the need for separate models and context-switching overhead.
- Released April 28, 2026 across Amazon SageMaker JumpStart, Hugging Face, and Together AI on day zero
- Single unified model handles video, images, audio, and text — replacing separate vision, speech, and language models
- Delivers up to 9x more efficient AI agents by reducing data passing and context loss between models
- Designed for agentic workloads and enterprise use cases requiring long-context multimodal reasoning
- Open model expanding NVIDIA's software and services offerings beyond hardware
