Perplexity launches Computer for Counsel, a multi-model legal layer. On June 24, Perplexity introduced Computer for Counsel, a set of agentic AI tools for legal teams working across litigation, employment, and intellectual property. The system draws on more than 20 frontier models and routes each task—research, contract review, or drafting—to the model it judges best suited, and it runs inside Microsoft 365 to draft in Word and pull files from SharePoint and Outlook. Perplexity said the product is available to its Enterprise and Max subscribers. (Law.com) (Perplexity)

Anthropic's Mythos found vulnerabilities in classified U.S. systems, an official says. A U.S. official told the Associated Press, in a report dated June 23, that Anthropic's Mythos model identified vulnerabilities in highly sensitive government computer systems within hours during a joint testing exercise with U.S. intelligence agencies. The official cautioned that finding the weaknesses does not mean the model exploited them. The tests ran through Anthropic's Project Glasswing initiative; more than 100 security experts who reviewed the models said they are "quite good" at finding software flaws but "not uniquely" so. The disclosure follows a government directive requiring Anthropic to bar foreign nationals from its latest Fable 5 and Mythos 5 models. (CNBC/AP) (SecurityWeek)

OpenAI leans toward delaying its IPO to 2027, jolting SoftBank. OpenAI is leaning toward postponing its initial public offering until 2027, according to reporting cited on June 26, as CEO Sam Altman holds out for a roughly $1 trillion valuation. Word of the possible delay sent SoftBank shares down as much as 12–13% in a single session, cutting about $38 billion from the company's market value; SoftBank's stake in OpenAI is on track to total around $65 billion later this year. Advisers reportedly framed the choice as waiting for the higher valuation or listing sooner at a lower one, with Altman said to call any reduction a "non-starter." (Bloomberg) (Quartz)

A24 gains access to DeepMind's research and infrastructure, and DeepMind researchers will help build new production workflows.

Palantir and Zeta Global strike a seven-year marketing-AI partnership.

The companies described a joint go-to-market effort aimed at Palantir's enterprise customers and projected the arrangement could generate more than $100 million in annual sales within about a year.
