A group of House Democrats wrote to House Speaker Mike Johnson, R-La., on Monday asking him to convene hearings at which the chief executives of OpenAI, Anthropic and other AI companies would testify under oath about a recent run of hacking incidents, per CNBC. Rep. Greg Casar, D-Texas, who chairs the Congressional Progressive Caucus, led the letter. Most signatories come from the party's progressive wing, though Rep. April McClain Delaney, D-Md., also signed. "The CEOs of the largest AI companies should answer questions under oath, and Americans should have a chance to hear from independent experts on the dangers posed by this technology," the lawmakers wrote, warning that the incidents "may be the canary in the coal mine warning of much more serious problems if these models continue to advance without regulation." The signers cannot compel the executives to appear: committee chairs control hearing schedules, and most House committees vest subpoena authority in their chair.

OpenAI introduced GPT-5.6-Cyber, a model trained for vulnerability research and exploit development, and made it available only through a gated tier called Daybreak Red rather than to the public. The company reported that GPT-5.6-Cyber completes 95.0% of requests on an internal benchmark covering exploit chains, authentication bypass and privilege escalation, against 1.5% for its general purpose GPT-5.6 Sol model and 57.3% for the earlier GPT-5.5-Cyber. Approved users include consultancies such as Accenture, IBM and Capgemini, plus security vendors including Palo Alto Networks, CrowdStrike and Cisco, BleepingComputer reported. "Access to the underlying models remains with the approved partner and is not transferred directly to the customer," OpenAI said, adding that safeguards may include identity verification, defined testing scopes, logging and human oversight.

The Department of Energy is collecting information from organizations that want to help build science specific AI models under its new Genesis Open Models Initiative, per FedScoop. The trained weights will be published for anyone to download and adapt. The first model, Genesis-Science-1, is already in development, with the U.S. open intelligence lab Arcee working alongside DOE scientists. Darío Gil, the department's undersecretary for science and director of the Genesis Mission, its program to point federal labs and supercomputers at national science goals, said the model will be "an open model trained on the real work of the national laboratories and answerable to the scientists who do it." Organizations seeking to join the foundation stage must apply by the end of this week and those offering data and environments for later rounds of training by Aug. 25, with further deadlines every three months.

Nvidia said Monday it has struck financing deals worth a half-trillion dollars with six investors including Apollo Global Management, BlackRock and Blackstone, per CNBC. The money will back data centers and chip manufacturing plants for both Nvidia's own projects and its partners', and will let customers secure financing without drawing on their own balance sheets. "In AI, compute is revenue," Jensen Huang, Nvidia's chief executive, said, adding that it was the first time technology chips have become an investable asset class. Nvidia's largest customers, among them Google, Microsoft and Meta Platforms, have collectively spent more than $1 trillion on AI projects and infrastructure over the past three years.
