Justin Herbert threw for 318 yards and three touchdowns in outdueling Patrick Mahomes, and the Los Angeles Chargers beat Kansas City 27-21 on Friday night in Sao Paulo, snapping a seven-game skid to the Kansas City Chiefs.

“It’s monumental,” Chargers coach Jim Harbaugh said. “September 5th will go down in some Charger lore, in my opinion. It was a big win.”

The NFL’s second game played in South America was streamed on YouTube, with Brazilian soccer superstar Neymar in attendance. Newly engaged pop superstar Taylor Swift wasn’t there to watch fiancé Travis Kelce and see Colombian singer Karol G perform at halftime.

Herbert became just the third quarterback in Chargers history with 300 yards and three TDs in a season opener. His 19-yard run on third-and-14 dashed any comeback hopes the Chiefs had with 2:21 to play. He finished 25 of 34 and was sacked three times.

“We knew it was going to be a dogfight, so we showed up today with our best effort,” Herbert said. “It was fun to see.”

Mahomes was 24 of 39 for 258 yards, one touchdown and two sacks.

Herbert’s 23-yard TD pass to Quentin Johnston extended the lead to 26-18 with 5:02 remaining in the fourth. They hooked up for a 5-yard TD on the Chargers’ opening drive of the game.

Chased by Khalil Mack, Mahomes threw incomplete to Marquise Brown on first-and-goal at the LA 9. Two more incomplete passes brought on Harrison Butker, whose 27-yard field goal cut the deficit to 27-21 with 2:34 remaining.

The Chiefs closed to 20-18 on Mahomes’ 37-yard TD pass to Kelce early in the fourth. The 2-point conversion failed as Mahomes’ pass was incomplete to Noah Gray.

The Chiefs were coming off their first TD drive in the third when they gave one right back to their AFC rivals. Herbert’s short left pass to Keenan Allen for 11 yards extended the Chargers’ lead to 19-12. Herbert and Allen had over 300 receptions together before Allen left for Chicago last season. He returned to Los Angeles last month.

The Chargers beat the Chiefs for the first time since Sept. 26, 2021, in Kansas City.

The Chiefs were already down two receivers to start the game, with Rashee Rice suspended to start the season and rookie Jalen Royals out with a knee injury.

They lost another one three snaps into the game.

Xavier Worthy and teammate Kelce collided on a third-down pass. Worthy had to be helped off the field and was later ruled out with a right shoulder injury.

Chargers linebacker Denzel Perryman didn’t return after leaving with an ankle injury in the third.

The Chiefs host Philadelphia on Sept. 14 in a Super Bowl rematch.

The Chargers visit Las Vegas on Sept. 15 in the second of three straight against division rivals.

NEW YORK (AP) — Artificial intelligence company Anthropic has agreed to pay $1.5 billion to settle a class-action lawsuit by book authors who say the company took pirated copies of their works to train its chatbot.

The landmark settlement, if approved by a judge as soon as Monday, could mark a turning point in legal battles between AI companies and the writers, visual artists and other creative professionals who accuse them of copyright infringement.

The company has agreed to pay authors or publishers about $3,000 for each of an estimated 500,000 books covered by the settlement.

“As best as we can tell, it’s the largest copyright recovery ever,” said Justin Nelson, a lawyer for the authors. “It is the first of its kind in the AI era.”

A trio of authors — thriller novelist Andrea Bartz and nonfiction writers Charles Graeber and Kirk Wallace Johnson — sued last year and now represent a broader group of writers and publishers whose books Anthropic downloaded to train its chatbot Claude.

A federal judge dealt the case a mixed ruling in June, finding that training AI chatbots on copyrighted books wasn’t illegal but that Anthropic wrongfully acquired millions of books through pirate websites.

If Anthropic had not settled, experts say losing the case after a scheduled December trial could have cost the San Francisco-based company even more money.

“We were looking at a strong possibility of multiple billions of dollars, enough to potentially cripple or even put Anthropic out of business,” said William Long, a legal analyst for Wolters Kluwer.

U.S. District Judge William Alsup of San Francisco has scheduled a Monday hearing to review the settlement terms.

Anthropic said in a statement Friday that the settlement, if approved, “will resolve the plaintiffs’ remaining legacy claims.”

“We remain committed to developing safe AI systems that help people and organizations extend their capabilities, advance scientific discovery, and solve complex problems,” said Aparna Sridhar, the company’s deputy general counsel.

As part of the settlement, the company has also agreed to destroy the original book files it downloaded.

Books are known to be important sources of data — in essence, billions of words carefully strung together — that are needed to build the AI large language models behind chatbots like Anthropic’s Claude and its chief rival, OpenAI’s ChatGPT.

Alsup’s June ruling found that Anthropic had downloaded more than 7 million digitized books that it “knew had been pirated.” It started with nearly 200,000 from an online library called Books3, assembled by AI researchers outside of OpenAI to match the vast collections on which ChatGPT was trained.

Debut thriller novel “The Lost Night” by Bartz, a lead plaintiff in the case, was among those found in the dataset.

The settlement could influence other disputes, including an ongoing lawsuit by authors and newspapers against OpenAI and its business partner Microsoft, and cases against Metaand Midjourney. And just as the Anthropic settlement terms were filed, another group of authors sued Apple on Friday in the same San Francisco federal court.

“This indicates that maybe for other cases, it’s possible for creators and AI companies to reach settlements without having to essentially go for broke in court,” said Long, the legal analyst.

The industry, including Anthropic, had largely praised Alsup’s June ruling because he found that training AI systems on copyrighted works so chatbots can produce their own passages of text qualified as “fair use” under U.S. copyright law because it was “quintessentially transformative.”

Comparing the AI model to “any reader aspiring to be a writer,” Alsup wrote that Anthropic “trained upon works not to race ahead and replicate or supplant them — but to turn a hard corner and create something different.”

But documents disclosed in court showed Anthropic employees’ internal concerns about the legality of their use of pirate sites. The company later shifted its approach and hired Tom Turvey, the former Google executive in charge of Google Books, a searchable library of digitized books that successfully weathered years of copyright battles.

With his help, Anthropic began buying books in bulk, tearing off the bindings and scanning each page before feeding the digitized versions into its AI model, according to court documents. That was legal but didn’t undo the earlier piracy, according to the judge.

NEW YORK (AP) — Carlos Alcaraz used his youth, athleticism and creativity to assert himself against the much more accomplished, but also much older, Novak Djokovic and beat the 24-time major champion 6-4, 7-6 (4), 6-2 at the U.S. Open on Friday for a berth in his third consecutive Grand Slam final.

By the end, Djokovic was “gassed out,” as he described it afterward, and seemed resigned to the result. The 38-year-old from Serbia reached the semifinals at all four Slams this season but exited in that round each time, three via losses to No. 2 Alcaraz, 22, or No. 1 Jannik Sinner, 24.

“It’s frustrating on the court when you are not able to keep up with that level physically, but at the same time, it’s something also expected, I guess,” Djokovic said. “It comes with time and with age.”

Alcaraz will face either defending champion Sinner or No. 25 Felix Auger-Aliassime for the championship on Sunday, when President Donald Trump plans to attend. Sinner is trying to become the first repeat men’s champion in New York since Roger Federer won the hard-court tournament five years in a row from 2004 through 2008.

Alcaraz hasn’t dropped a set as he pursues his sixth major title and second at Flushing Meadows. He defeated Sinner at the French Open in June and lost to his rival at Wimbledon in July.

Go back to April, and Alcaraz is 44-2, making it to the finals at each of his last eight tour-level events.

“It’s something that I’m working on, just the consistency on the matches, on the tournaments, on the year, in general. Just not having up-and-downs in (a) match,” Alcaraz said. “Probably, I’m just getting mature, just getting to know myself much better, what I need on, off the court.”

Alcaraz had lost his two most recent matches against Djokovic — in the gold-medal final at the Paris Olympics last year, and in the Australian Open quarterfinals this January.

“It’s not easy playing against him, to be honest,” Alcaraz said. “I’m thinking about the legend; what he has achieved in his career. It’s difficult not to think about it.”

Djokovic’s bid to become the first player in the sport’s history to get Slam No. 25 was blocked again, and he thinks part of the issue is trying to overcome much younger men in best-of-five set matches.

“I still want to play … (a) full Grand Slam season next year,” Djokovic said. “Let’s see whether that’s going to happen or not, but … Slams are Slams. They are just different from any other tournament. They are the pillars of our sport, the most important tournaments we have. But I do fancy my chances a bit more in best-of-three.”

Alcaraz and Sinner have combined to collect the past seven major championships and nine of the last 12. Djokovic won the other three in that span, most recently at the 2023 U.S. Open.

Djokovic’s shots were not quite on-target early and, but for a brief interlude in the second set, his usual verve was not present. He rolled his eyes after one miss, grimaced after another. At changeovers, he flexed or stretched his neck, which bothered him earlier in the tournament, and also was looked at by a trainer.

There also was the occasional bit of brilliance, including a two-handed backhand passing shot that drew raucous roars from the crowd, which often cried out his nickname, “No-le!” and seemed to want to will him to at least make things more competitive, if not win.

Djokovic celebrated by strutting to his towel box while shaking his right hand over and over, as though to say, “Hoo-boy! How nice was that?”

Djokovic even managed to steal one of Alcaraz’s service games while taking a 3-0 lead in the second set. Might this portend a long, tight match?

Nope. Alcaraz immediately snapped to, taking the next three games, including one scooped cross-court forehand passing winner that was so superb even Djokovic felt compelled to applaud with his racket.

Alcaraz never faced another break point.

“Today, I’d say, it wasn’t the best level of the tournament for me,” said Alcaraz, whose 30 unforced errors were the same as Djokovic’s total, “but I just kept a cool level (from) the beginning until the last point.”

He was wearing a pink, sleeveless shirt and sporting nearly a full head of hair less than two weeks after showing up with a buzz cut he said was necessary when his brother tried to play barber but messed up.

Asked whether he’ll stick with the new look if he wins on Sunday, Alcaraz smiled and replied: “Even better. You will see. … Surprise, surprise.”
