This latest release comes months after the firm's warning that its original Mythos model could spot and exploit vulnerabilities in critical software.

Anthropic is also releasing a new version of Mythos called Mythos 5 without some of the safeguards, which will be available to select groups through an initiative called Project Glasswing.

Now to the latest primary votes in the United States.

In Maine, Democrat Graham Plattner has decisively won the party's Senate primary, securing about 74% of the vote.

The win comes despite a series of controversies surrounding his campaign, including revelations about a Nazi symbol tattoo that he has since covered up, and more recently, a New York Times report in which some former girlfriends described his behavior as disturbing, allegations that Plattner has denied.

Speaking to supporters after his victory, Plattner addressed both the election result and the controversies that have dogged his campaign.

Graham Plattner will now face Republican incumbent Susan Collins, who is seeking a sixth term in the US Senate.

In the other key race of the night, South Carolina Republican Lindsey Graham is projected to win his party's Senate primary, putting him on course to seek another term in November.

Experts are predicting upward pressure on SpaceX stock before its IPO has even been priced.

The prospect of billions in demand from index tracking funds risks creating a feedback loop, driving shares even higher, according to some market observers.

Entropic, a provider of index rebalancing forecasts, says about 30% of SpaceX's free float is now set to be owned by passive investors after just 15 days of trading.

Some expect a situation where flows are determined by the company's market value, which could be temporarily inflated by arbitrages preparing for the mechanical bid.

That combined with the existing buzz around founder Elon Musk and AI means the risk is that index funds themselves could help drive up the price that they end up having to pay.
