OpenAI, Meta, and Anthropic Face Scrutiny Over AI Safety and Expansion

In late July 2026, OpenAI, Meta, and Anthropic came under increased scrutiny over the safety and direction of artificial intelligence. OpenAI revealed that a security breach involving one of its AI systems affected four platforms, and its CEO Sam Altman met with lawmakers to address concerns. Meanwhile, Meta's Mark Zuckerberg defended his company's AI investments to skeptical investors and criticized rivals OpenAI and Anthropic for their more closed approaches. At the same time, employees from OpenAI, Google, and Meta signed a letter calling for mechanisms to slow down AI progress, and OpenAI and Anthropic separately asked the U.S. government to consider regulating the pace of AI development.
