xAI's Grok Build coding tool was automatically uploading entire code repositories to Google Cloud storage — including files explicitly excluded and deleted secrets. xAI disabled the feature after security researchers at Cereblab published their findings.
Google DeepMind, Microsoft, and xAI have agreed to pre-deployment AI model evaluations by CAISI, the US Commerce Department's AI standards body. The announcement came May 5, 2026; CAISI has conducted 40 reviews to date. The White House is considering an executive order on AI oversight.
xAI has released Grok 4.3 — a model with an always-on reasoning architecture, 1M token context, and prices cut by more than 50%. The model targets enterprise workloads, but independent benchmarks flag weaknesses in coding and math. It comes alongside Custom Voices — voice cloning from a 2-minute sample.
Testifying in a California federal court, Musk confirmed xAI used distillation on OpenAI models to train Grok — while suing OpenAI for abandoning its founding principles.
Google has granted the U.S. Department of Defense access to its AI models on classified networks, according to reports published April 28, 2026. The move came one day after Anthropic lost its legal standoff with the Pentagon and was formally designated a national security supply-chain risk — the first American company to receive that label. With Google's agreement, the DoD has now secured frontier AI access from three major providers: OpenAI, xAI, and Google.
