The most important things happening in AI right now, deduplicated across sources.

1. Google unveils Gemini 4 Argon, but gates it. Google announced Gemini 4 Argon, its next frontier model, pitched at software engineering, enterprise knowledge work and cybersecurity defense. Access is limited for now to "trusted cyber defenders", so most users cannot try it yet. Sources: Ars Technica · The Verge · TechCrunch · Google DeepMind

2. White House gets AI labs to sign a voluntary safety pledge. Trump and leading AI companies signed a "Joint Commitment on Frontier Responsibilities", promising safety tests and extra controls on frontier models. Coverage is skeptical: the pledge is non-binding and relies on the firms policing themselves. Sources: Ars Technica · Wired · The Verge · The Register

3. OpenAI delays its newest Astra model and its IPO, and gets sued. OpenAI held back its latest Astra model for more safety work, and its IPO plans are slipping while it seeks another $30 billion privately. A California nonprofit sued over the Hugging Face hack carried out by OpenAI's agents, asking a court to halt what it calls unsafe development.

4. DevDay: OpenAI's always-on Dots take on Meta's Muse. At DevDay OpenAI introduced Dots, always-on agents that connect to your apps and handle multistep tasks proactively, a direct answer to Meta's Muse. It also shipped GPT-6.1 Sol, billed as near-Astra intelligence at one fifth of the API price. Meta, meanwhile, disputed a journalist's claim that Muse read his private messages without permission.

5. Distillation fight: frontier capabilities are leaking. OpenAI says it disrupted a coordinated campaign to extract its models' protected reasoning through distillation, which The Register ties to a Chinese model. Anthropic's red team found that GLM-5.3 can now develop full control-flow hijacks in 4% of binary-exploitation trials against 6% for Claude Mythos Preview, a threshold earlier models did not cross. Sources: OpenAI · The Register · Simon Willison

6. AI moves into biology, with caveats. Anthropic says Claude discovered a CRISPR-like system, but experts note the lab experiments are still pending while the announcement is already public. Google DeepMind showed SynthID Bio, a proof of concept that watermarks AI-designed proteins without breaking their function, aimed at biosecurity.
