Shortly after Hunter Lightman joined OpenAI as a researcher in 2022, he watched his colleagues launch ChatGPT, one of the fastest-growing products ever. Meanwhile, Lightman quietly worked on a team teaching OpenAI’s models to solve high school math competitions.  Today that team, known as MathGen, is considered instrumental to OpenAI’s industry-leading effort to create AI reasoning models: the core technology behind AI agents that can do tasks on a computer like a human would. “We were trying to make the models better at mathematical reasoning, which at the time they weren’t very good at,” Lightman told TechCrunch, describing MathGen’s early…

Facebook Tweet Email Link A far-right Israeli minister sparked outrage on Sunday after leading a group of worshippers in prayer at the most sensitive holy site in Jerusalem, despite a decades-old agreement that bars Jews from worshipping there. National Security Minister Itamar Ben Gvir, who has previously been convicted for supporting terrorism and inciting anti-Arab racism in Israel, commemorated Tisha B’Av, a Jewish day of mourning, in the Al Aqsa Mosque compound, known to Jews as Temple Mount. On Tisha B’Av, Jews mark the destruction of two ancient temples that once stood on the land. While there, he called for…

There’s an airline booking strategy that savvy travelers use to access better seats, onboard amenities, and in-flight perks: they look for fifth-freedom flights.A fifth-freedom flight is the official term for a route operated by an international carrier between two countries where the carrier is not based. Usually, airlines can only operate routes that start or end in their home countries to keep competition fair. Fifth-freedom flights, however, are a bit of a workaround. Carriers are allowed to operate flights between two foreign countries, as long as the itinerary eventually ends in their home nation.  With fifth-freedom flights, the first destination…

Sarah Murray recalls the first time she saw an artificial model in fashion: It was 2023, and a beautiful young woman of color donned a Levi’s denim overall dress. Murray, a commercial model herself, said it made her feel sad and exhausted.  The iconic denim company had teamed up with the AI studio Lalaland.ai to create “diverse” digital fashion models for more inclusive ads. For an industry that has failed for years to employ diverse human models, the backlash was swift, with New York Magazine calling the decision “artificial diversity.”  “Modeling as a profession is already challenging enough without having…

Facebook Tweet Email Link Rome  —  European countries hoping to mirror Italy’s controversial practice of sending some asylum seekers rescued at sea to overseas deportation centers have been dealt a setback by Europe’s top court. On Friday, the European Court of Justice (ECJ) ruled that while Italy could still utilize the centers it runs in the Albanian cities of Shengiin and Gjader, who can be sent there must be more closely examined to ensure that asylum seekers aren’t being sent back to dangerous situations in their home countries. The court said that a country of origin can only be considered…

Facebook Tweet Email Link Rome just wrapped the equivalent of a Catholic Woodstock. Its headline act: The new American Pope.

This past spring, when I pointed my car out of Inverness to begin a loop around Scotland’s craggy northern shoreline, I was expecting trouble ahead. A decade ago, when the North Highland Initiative — a development charity set up under then-Prince Charles — renamed the circuit the North Coast 500 and started promoting the drive to tourists, I had been unconvinced it would work. I approved of any initiative aimed…
