OpenAI said Thursday it is hiring Dali Rajic, president and chief operating officer of Alphabet-owned cybersecurity firm Wiz, to replace Denise Dresser as its new chief revenue officer. Dresser is departing the company “to pursue other opportunities following a transition period,” according to a blog post. Dresser, the former CEO of Slack at Salesforce, is leaving after just eight months. The exit is the latest in a string of departures from the ChatGPT maker. Brad Lightcap, who most recently led OpenAI’s special projects division and formerly was its chief operating officer, told staff on Tuesday that he was leaving the company. In July, OpenAI’s CEO of AGI deployment, Fidji Simo, officially announced that she would be stepping down to a part-time advisor role after taking medical leave. Dresser’s departure is somewhat surprising, given she had gotten more visibility as Simo stepped back from her duties in recent months. Rajic joins as OpenAI looks to ramp up its enterprise sales of AI, which have lagged sales at Anthropic lately. OpenAI president Greg Brockman recently said in an internal note that the company’s total annualized revenue had grown more than 20% month-over-month in July, and revenue from business customers had grown 32% in that same time period, according to a copy of the note seen by The Information. Dealbook and Bloomberg first reported some details of the revenue growth metrics.

Tarun Chhabra, a former Biden administration official who serves as Anthropic’s head of national security policy, is transitioning out of his role, according to a spokesperson. Chhabra will take on a new advisory role at Anthropic focused on geopolitics and national security policy and will continue to work with Anthropic leadership, the spokesperson added. It’s unclear if he will remain full-time. The move comes amid a broader restructuring of Anthropic’s government affairs operations, which will now sit under Mariano-Florentino Cuéllar, who Anthropic announced as its new chief global affairs officer earlier this month. Cuéllar previously served as a justice of the Supreme Court of California and President of the Carnegie Endowment for International Peace. In the newly created position, he will oversee policy and government relationships, including managing other key leaders like Sarah Heck, Anthropic’s head of public policy. Laura Loomer, a far-right influencer, posted on X earlier that Chhabra had been “fired.“ The changes come after months of tension with the Trump Administration. Anthropic has hired several former Biden administration AI policymakers into key roles at the company, helping fuel mistrust within the Trump administration, The Information previously reported. But the relationship further strayed earlier this year when the Department of Defense designated Anthropic as a supply chain risk after a disagreement over how the military could use Anthropic’s AI. Then in June, the White House imposed export controls on Anthropic over apparent security vulnerabilities in its latest models, Fable and Mythos. The administration lifted the restrictions later in the month after it reached an accord with Anthropic.

Chinese AI developer Z.ai on Friday released its new open-source model, GLM-5.3, saying its cybersecurity capabilities are on par with Anthropic’s Mythos 5. Beijing-based Z.ai, also known as Zhipu in Chinese, said GLM-5.3 has achieved significant improvements from its predecessor, GLM-5.2, in both coding and cybersecurity. In some security tasks, “the performance of GLM-5.3 is the same as Mythos 5, showing the strong potential for network security defense scenarios,” the company said in a post on its official WeChat account. To emphasize the role of GLM-5.3 as an open-source cyber defense tool, Z.ai referenced an incident last month when an AI agent developed by OpenAI went rogue and hacked into the systems of AI model repository Hugging Face. Hugging Face used GLM-5.2 to analyze the data and contain the breach, after its security team couldn’t use U.S. frontier models for forensics due to built-in guardrails. Z.ai stated in the WeChat post that the lesson from the Hugging Face incident is that “if the powerful attack ability is spreading, the defensive ability cannot be limited to a few closed-source model companies.” The release of GLM-5.3 is the latest example of how Chinese AI companies are rolling out more capable open-source models that directly challenge U.S. frontier models from Anthropic and OpenAI. Last month, Moonshot AI’s latest model, Kimi K3, became a global sensation by offering frontier-level coding performance.

Workday shares rose 18% in Thursday trading after Reuters reported that the HR software company is in talks to be acquired by private equity firm Silver Lake. The jump trimmed Workday stock’s year-to-date loss to roughly 4%, a mild decline relative to fellow software firms such as Salesforce and ServiceNow, which are facing pressure to show more growth from AI products. Reuters reported that talks are ongoing for the potential deal, and Silver Lake, which owns many other software firms, could tap additional investors to help finance it. Workday declined to comment on the report, while Silver Lake spokespeople did not immediately respond to a request for comment. Workday reports its July quarter results at the end of the month. Workday shares jumped after its April quarter results showed usage of its AI agents climbing even as revenue growth slowed.
