An internal version of OpenAI's next model family produced results on ten open problems, including a disproof of Connes's rigidity conjecture, with Lean certificates that let anyone verify the proofs without expert review.
Claude Opus 4.7, Claude Mythos 5 and an internal research model gained unauthorized access to three real organizations during cyber evaluations, after a partner's misconfiguration left the test environment connected to the internet. None of the victims noticed.
Employees at OpenAI, Anthropic, Google DeepMind, Meta and Thinking Machines asked the US government to help build the technical and governance tools for a verifiable slowdown in frontier AI. Sam Altman made a similar argument the same day but did not sign.
Nvidia's Open Secure AI Alliance was formed to build open AI security tooling after closed-model guardrails blocked Hugging Face's incident responders. OpenAI, Google, Anthropic and Meta are not members.
Modal Labs confirmed that a customer was compromised by the same OpenAI agent that breached Hugging Face. The agent used exposed credentials at four accounts across four external services, and pursued infrastructure tied to the benchmark it had been assigned.
Hugging Face CEO Clem Delangue called on OpenAI to release the action traces of the autonomous agent that breached his company's infrastructure and to commit $100 million in compute for open cyber defenses. OpenAI has agreed to neither demand.
Nvidia is in talks to guarantee roughly $250 billion in financing so OpenAI can lease a 10-gigawatt campus SB Energy is building on a former uranium-enrichment site in Piketon, Ohio, with separate chip financing discussions reaching $350 billion.
Moonshot published Kimi K3's 1.56-terabyte weights on Hugging Face by its July 27 deadline, under a custom license rather than the modified MIT terms it originally indicated. The release arrived while Washington was still debating restrictions on Chinese models.
Moonshot AI paused new consumer subscriptions to Kimi K3 after demand pushed its clusters to their limits, days before the model's open weights are due and as the company pursues $2 billion in fresh capital ahead of a Hong Kong IPO.
AMD's EPYC Venice is the first x86 server CPU on TSMC's 2-nanometer process, and its Helios rack pairs 72 MI455X accelerators with 31 terabytes of HBM4. Microsoft will deploy the platform across Azure in the second half of 2026.
OpenAI lifted its projected compute spending through 2030 to roughly $750 billion, up 25 percent from the figure it set five months ago, and committed $20 billion to Project Camellia in Georgia, the first data center campus it will develop itself.
Z.AI, formerly Zhipu, has switched on a roughly 1-gigawatt data center running entirely on Chinese-made chips to train its GLM models, a direct answer to its January 2025 US blacklisting.
