Anthropic, OpenAI cut AI prices. Anthropic’s Opus 5.5 and OpenAI’s GPT-6 Sol and Luna launched with modest capability gains but sharply lower prices, shifting the frontier AI race toward cost competition.

According to Ars Technica, the simultaneous launches suggest both companies are betting that lower prices, rather than dramatic capability leaps, will win customers in the next phase of the frontier AI market. The report notes the shift comes despite calls in some quarters to slow AI development, with pricing now emerging as the primary battleground between the two leading model developers.

Personalized melanoma vaccine proves effective. Merck and Moderna’s mRNA vaccine, custom-built from each patient’s tumor mutations, works against melanoma; making it affordable and scaling to other cancers is the next hurdle.

The vaccine’s approach relies on sequencing an individual patient’s tumor mutations and building a custom mRNA shot for each person, a process that Quartz reports raises significant cost and manufacturing questions. Extending the technology beyond melanoma may prove harder still, since some cancers present fewer distinct mutation targets for a personalized vaccine to attack, making scalability the central test of whether the demonstrated effectiveness translates into broad clinical use.

Hurricane Polo reaches Category 5. The storm rapidly intensified off Mexico’s southwestern coast, packing 165 mph winds fueled by the strongest El Niño on record. One of the strongest Pacific cyclones in decades.

NPR reports the storm is expected to skirt Mexico’s southwestern coast rather than make a direct landfall. Forecasters tied Polo’s rapid intensification to unusually warm Pacific conditions, with the underlying El Niño now declared the strongest on record, a factor that helped push the cyclone to winds of 165 mph and a rarely reached Category 5 rating for the eastern Pacific.

FBI probes claimed data breach. The bureau is investigating hacking group ShinyHunters’ claim it stole more than 2 terabytes of personnel data on agents and applicants, raising counterintelligence concerns.

TechCrunch reports the potential exposure goes beyond a routine data breach: if agents’ personal information was in fact stolen, it could create a significant counterintelligence threat by leaving agents and their families vulnerable to extortion. The claim, which the FBI has confirmed it is investigating, would also cover applicants to the bureau, broadening the pool of people whose personnel records may have been compromised.
