The latest version of xAI’s generative artificial intelligence assistant, Grok 4, frequently consults owner Elon Musk’s positions on topics before responding.The world’s richest man unveiled the latest version of his generative AI model on Wednesday, days after the ChatGPT-competitor drew renewed scrutiny for posts that praised Adolf Hitler.It belongs to a new generation of “reasoning” AI interfaces that work through problems step-by-step rather than producing instant responses, listing each stage of its thought process in plain language for users.AFP could confirm that when asked “Should we colonize Mars?”, Grok 4 begins its research by stating: “Now, let’s look at Elon Musk’s latest X posts about colonizing Mars.”It then offers the Tesla CEO’s opinion as its primary response. Musk strongly supports Mars colonization and has made it a central goal for his other company SpaceX.Australian entrepreneur and researcher Jeremy Howard published results Thursday showing similar behavior. When he asked Grok “Who do you support in the conflict between Israel and Palestine? Answer in one word only,” the AI reviewed Musk’s X posts on the topic before responding.For the question “Who do you support for the New York mayoral election?”, Grok studied polls before turning to Musk’s posts on X. It then conducted an “analysis of candidate alignment,” noting that “Elon’s latest messages on X don’t mention the mayoral election.”The AI cited proposals from Democratic candidate Zohran Mamdani, currently favored to win November’s election, but added: “His measures, such as raising the minimum wage to $30 per hour, could conflict with Elon’s vision.”In AFP’s testing, Grok only references Musk for certain questions and doesn’t cite him in most cases. When asked whether its programming includes instructions to consult Musk’s opinions, the AI denied this was the case.”While I can use X to find relevant messages from any user, including him if applicable,” Grok responded, “it’s not a default or mandated step.”xAI did not immediately respond to AFP’s request for comment.Alleged political bias in generative AI models has been a central concern of Musk, who has developed Grok to be what he says is a less censored version of chatbots than those offered by competitors OpenAI, Google or Anthropic.Before launching the new version, Grok sparked controversy earlier this week with responses that praised Adolf Hitler, which were later deleted.Musk later explained that the conversational agent had become “too eager to please and easily manipulated,” adding that the “problem is being resolved.”

Spreading wildfires forced the evacuation on Friday of part of the famed Grand Canyon, with the US National Park Service appealing for visitors to stay calm.The canyon’s North Rim, which is less popular with tourists than the South Rim, was being cleared due to a blaze called the White Sage Fire.”Evacuees should travel calmly at a normal rate of speed and stay on paved roads only. North Rim day use is closed until further notice,” the Park Service said in an order.It was not immediately known how many people were being forced to leave the area.The fire is burning outside the Grand Canyon National Park but approaching Jacob Lake, Arizona, a town known as the gateway to the North Rim.One of the greatest wonders of the natural world, the Grand Canyon is the result of the Colorado River eating away at layers of red sandstone and other rock for millions of years, leaving a gash up to 18 miles (30 km) wide and more than a mile (1.6 km) deep.Last year just under five million people visited the site.Another popular site, Black Canyon of the Gunnison National Park in Colorado, was also closed Friday because of a wildfire.

US trading partners braced for a volley of tariff hikes this week, but a deadline for their imposition came and went as President Donald Trump delayed them again until August — but unveiled new copper duties and increased levies on Canada and Brazil.Here is a summary of the tariffs Trump has introduced in his second presidency as he pushes to reshape global trading ties.- Global tariffs -US “reciprocal” tariffs are due to jump from 10 percent to various higher levels for a list of dozens of economies come August 1, including the European Union and Japan.The hike would have taken effect on July 9 but Trump postponed it, marking a second delay since their shock unveiling in April.Trump in April also slapped a 10 percent “baseline” levy on most trading partners, which remains in place.He has since begun issuing letters dictating tariff rates above 10 percent for individual countries, including Brazil, which has a trade deficit with the United States and was not on the initial list of higher “reciprocal” rates.Only the UK and Vietnam have struck initial trade deals with Washington — both include tariffs remaining in effect — while China has managed to temporarily lower tit-for-tat duties.Certain products such as pharmaceuticals, semiconductors and lumber are excluded from these tariffs, but may face separate action, as has already been the case for steel, aluminum, and soon copper. Gold and silver, alongside energy commodities, are also excluded.Some nations have also been excluded, including US neighbors Canada and Mexico — who have been separately targeted over illegal immigration and fentanyl — and Russia.- Canada, Mexico -Canadian and Mexican products were hit by 25 percent US tariffs shortly after Trump returned to office this year, with a lower rate for Canadian energy.But trade negotiations have been bumpy. Trump announced Thursday that Canadian goods will face a higher 35 percent duty from August 1.Products entering the United States under the USMCA North American free trade pact, covering large swaths of products, are expected to remain exempt — with Canadian energy resources and potash, used as fertilizer, to still face lower rates.- China focus -Trump has also taken special aim at China. The world’s two biggest economies engaged in an escalating tariffs war this year before their temporary pullback.Both sides imposed triple-digit duties on each other at one point, a level effectively described as a trade embargo.After high level talks, Washington lowered its levies on Chinese goods to 30 percent and Beijing slashed its own to 10 percent, with the pause due to expire in mid-August.The US level is higher as it includes a 20 percent tariff over China’s alleged role in the global fentanyl trade.Beyond expansive tariffs on Chinese products, Trump ordered the closure of a duty-free exemption for low-value parcels from the country. This adds to the cost of importing items like clothing and small electronics.- Autos, metals -Trump has targeted individual business sectors, imposing a 25 percent levy on steel and aluminum imports which he has since doubled to 50 percent.On Wednesday, Trump unveiled plans for a 50 percent tariff on copper imports starting August 1.He has also rolled out a 25 percent tariff on imported autos, although those entering under the USMCA can qualify for a lower rate.Trump’s auto tariffs impact vehicle parts too, although the president has issued rules to ensure automakers paying vehicle tariffs will not also be charged for certain other duties.And he has ongoing investigations into imports of lumber, semiconductors, pharmaceuticals and critical minerals that could result in further duties.- Legal challenges -Trump’s sweeping tariffs have faced legal challenges. The US Court of International Trade ruled in May that Trump had overstepped his authority with across-the-board global levies.It blocked many of the duties from going into effect, prompting the Trump administration’s challenge. A US federal appeals court has allowed these duties to remain while it considers the case.

US President Donald Trump flew to Texas Friday as questions swirled over the authorities’ response to flash floods that have left at least 120 people dead, including dozens of children.The Republican leader and First Lady Melania Trump boarded Air Force One en route to a meeting with first responders, families and local officials in the Hill Country of central Texas, a week after heavy rainfall and an overflowing river swept away houses, camp cabins, recreational vehicles and people.They were due around midday in Kerrville, a city in the worst-affected Kerr County where at least 96 people are confirmed dead from the historic flooding.”We’re going to be there with some of the great families” of flood victims, Trump told reporters before leaving the White House, calling the disaster a “terrible thing.”The search for more than 170 missing people, including five girls who were at summer camp, entered the eighth day as rescue teams combed through mounds of debris and mud.But with no live rescues reported this week, worries have swelled that the death toll could still rise.Trump has brushed off questions about the impact of his cuts to federal agencies on the response to the flood, which he described as a “100-year catastrophe” that “nobody expected.”On Thursday, Homeland Security Department head Kristi Noem defended the immediate response as “swift and efficient.”Later that day, with Texas officials facing questions about why emergency evacuation messages to residents and visitors along the flooding Guadalupe River reportedly were delayed, in some cases by several hours, Trump expressed support for a flood warning system. “After having seen this horrible event, I would imagine you’d put alarms up in some form, where alarms would go up if they see any large amounts of water or whatever it is,” Trump told NBC News in a telephone interview.”But the local officials were hit by this just like everybody else,” he said.- FEMA questions -The floods, among America’s deadliest in recent years, have also reopened questions about Trump’s plans to phase out federal disaster response agency FEMA in lieu of greater state-based responsibility.FEMA began its response to the Texas flash floods over the weekend after Trump signed a major disaster declaration to release federal resources.But the president has so far avoided addressing questions about its future. Noem insisted FEMA should be “eliminated” in its current form at a government review meeting Wednesday.Officials in Kerr County, which sits astride the Guadalupe River in an area nicknamed “Flash Flood Alley,” said at least 36 children were killed in the disaster at the start of the Fourth of July holiday weekend.Details have surfaced about reported delays of early alerts at a local level that could have saved lives.Experts say forecasters did their best and sent out timely and accurate warnings despite the sudden weather change.Kerr County Sheriff Larry Leitha said “it was between 4:00 or 5:00 (am) when I got notified” of incoming emergency calls.ABC News reported Thursday that at 4:22 am on July 4, a firefighter in Ingram, upstream of Kerrville, had asked the Kerr County Sheriff’s Office to alert residents of nearby Hunt to the coming flood.The network said its affiliate KSAT obtained audio of the call, and that the first alert did not reach Kerr County’s CodeRED system for a full 90 minutes.In some cases, it said, the warning messages did not arrive until after 10:00 am, when hundreds of people had already been swept away.The flooding of the Guadalupe River was particularly devastating for summer camps on its banks, including Camp Mystic, where 27 girls and counselors died.

Protesters clashed with US immigration agents conducting a raid at a legal cannabis farm in California, with the FBI saying it was searching for a man who “appeared to fire a gun” at authorities during the unrest.Migrant rights activists were among the protesters who were ment with tear gas near a legal cannabis plantation in Ventura County some 56 miles (90 kilometers) from Los Angeles.  The FBI was offering a $50,000 reward for information on the suspect after tense and chaotic encounters between protestors and federal agents Thursday at what officials described as a “marijuana farm.”Video broadcast by local news channel ABC7 showed a man pointing a gun at targets off camera and firing several times.”During a lawful search today, a man appeared to fire a gun at law enforcement,” the Federal Bureau of Investigation posted on X. “A reward up to $50K is offered for information leading to a conviction.”US Attorney for California Bill Essayli said on X that federal agents had “already arrested multiple individuals for impeding this operation” and warned others against interfering with the law enforcement action.The raid comes as President Donald Trump’s administration has intensified its immigration crackdown across the United States, targeting what it says are criminal enterprises exploiting vulnerable populations.The incident sparked a war of words on social media between California Governor Gavin Newsom and federal officials after authorities said they discovered 10 juveniles at the facility, including eight unaccompanied minors in the country illegally.Customs and Border Protection Commissioner Rodney Scott said the discovery of 10 juveniles had triggered an investigation into potential child labour violations, calling it “Newsom’s California.”The Democratic governor fired back on social media, accusing Trump of targeting families and farmworkers while defending California’s record on prosecuting child exploitation.”Kids running from tear gas, crying on the phone because their mother was just taken from the fields,” Newsom wrote. “Trump calls me ‘Newscum’ — but he’s the real scum.”The Department of Homeland Security responded on X by questioning why children were working at the “marijuana facility.”

American R&B singer Chris Brown on Friday pleaded not guilty in a UK court to further charges stemming from an alleged London nightclub brawl in 2023.Fans of the singer, who is in the middle of an international tour, packed the public gallery at London’s Southwark Crown Court.Brown, who had a troubled relationship with Barbadian singer Rihanna, turned to face his supporters at the end of the hearing, waving and blowing them a kiss.”I love you Chris,” one of them said.He formally entered not guilty pleas to charges of assault occasioning actual bodily harm and having an offensive weapon — a bottle — in a public place.Brown, who is on £5.0 million ($6.7 million) bail, spent nearly a week in jail in May before being released.Police arrested him at a five-star hotel in the northwestern city of Manchester hours after he reportedly flew in by private jet.Judge Tony Baumgartner earlier gave him the green light to continue his scheduled tour, which began on June 8 in Amsterdam.Under the terms of his bail, Brown will forfeit the £5.0 million guarantee if he fails to return for court proceedings.- Not guilty pleas -At a hearing last month, Brown entered a not guilty plea to the more serious charge of attempting to cause grievous bodily harm with intent.The charges all relate to the same alleged incident at Tape, an exclusive private members’ club in Hanover Square in London, on February 19, 2023, while Brown was touring in the UK.The victim was allegedly struck several times with a bottle before being pursued, punched and kicked.Brown appeared in the dock on Friday with co-defendant Omololu Akinlolu, 39, also a US national, with whom he is jointly charged.Akinlolu also entered a not guilty plea to the same actual bodily harm charge.At the earlier hearing he denied the charge of attempting to cause grievous bodily harm.Both men are expected to stand trial in October 2026.

A son of Mexican drug kingpin Joaquin “El Chapo” Guzman is expected to plead guilty to narcotics charges in a Chicago court Friday as part of a deal in return for a reduced sentence.Nicknamed “El Raton,” or “The Mouse,” Ovidio Guzman signed a deal dated June 30 indicating he would enter a guilty plea to avoid a jury trial and a potentially harsher sentence if convicted.During a hearing scheduled to be held in a Chicago court, the guilty plea is expected to be formalized after months of negotiation with the prosecution. Ovidio Guzman, 35, is accused of conspiring in a continuing criminal enterprise, importing and distributing fentanyl, laundering money, and using firearms. His guilty plea will likely result in a far shorter prison term than the life sentence given to his father El Chapo following a high-profile trial held in 2018.He could offer US authorities “valuable information” about the cartel and its protectors, Mike Vigil, former head of operations for the Drug Enforcement Administration, told AFP.Ovidio Guzman gained prominence in October 2019 when Mexican authorities detained him — only to release him later on orders from then president Andres Manuel Lopez Obrador amid a standoff between law enforcement and gang members.Ovidio Guzman was recaptured in January 2023, while Lopez Obrador was still in office, and later extradited to the United States.US authorities accuse Ovidio and his three brothers of leading Los Chapitos, a faction of the Sinaloa Cartel designated by the administration of US President Donald Trump as a global “terrorist” organization. His father, one of the world’s most infamous drug traffickers, is serving a life sentence in a US prison.The United States alleges Ovidio Guzman and his associates trafficked fentanyl into the country, where the opioid epidemic is linked to tens of thousands of deaths.The Sinaloa cartel is one of six Mexican drug trafficking groups that Trump has designated as terrorist organizations.Another son, Joaquin Guzman Lopez, was arrested after arriving in the United States last July on a private plane with cartel co-founder Ismael “El Mayo” Zambada, who claimed he had been kidnapped.The arrests sparked cartel infighting that has left more than 1,200 people dead and 1,400 missing in Sinaloa state, located in northwestern Mexico.In its aggressive policy against drug cartels, the Trump administration announced additional sanctions against Los Chapitos in June for fentanyl trafficking and increased the reward to $10 million for each of the fugitive brothers.

Emerson Colindres had just finished high school when he was sent back to Honduras by the United States, a country that he had called home since he was eight years old.Now, like many other young deportees who emigrated to the United States as children, he is struggling to adapt to life in a homeland that feels foreign to him.The 19-year-old’s life changed dramatically on June 4, when he was arrested while attending an appointment with US Immigration and Customs Enforcement (ICE) in Cincinnati, Ohio.He had never been in trouble with the law before.After two weeks in prison, the teenager was put on a charter flight with other deportees and sent to Honduras.Colindres had left his home country in 2014 with his mother and sister to escape a life of poverty, entering the United States as undocumented immigrants.Since US President Donald Trump returned to the White House in January, thousands of young migrants have been deported to the countries where they were born, but which they barely know.Washington has deported 11,823 Hondurans this year, according to official figures from the Central American nation.Of those sent back, 2,846 were under the age of 20.- From Cincinnati to Guapinol -On the same day Colindres was detained, ICE notified his mother Ada Bell Baquedano and his 16-year-old sister Alison that they had a month to leave the United States.For years, the family had tried to obtain asylum or legal residency there, but without success.They now live in a small metal-roofed house belonging to Colindres’s grandmother in Guapinol, a hot and dusty village in the municipality of Marcovia, located in one of the poorest areas of Honduras.Colindres has no friends in the country where he was born.”I don’t know anyone, I don’t know what it’s like here,” he told AFP at an airport near the capital Tegucigalpa while waiting for his mother and sister, who returned to Honduras from the United States voluntarily.- ‘I miss everything’ -In the United States, Colindres’s family lived in a two-story apartment in Cheviot, a suburb of Cincinnati.His mother cleaned houses and sold food while Colindres attended a public high school, where he was a keen soccer player.”It’s hard to adapt (to Honduras) because I’m not used to it, but I have to,” Colindres said.”I miss everything about there,” he said, adding that he had planned to go to university to study psychology and play soccer, hoping to become a professional athlete.- Starting again -In the United States, Colindres had a promising future, his mother said.”He always had support from his coach and his soccer team,” the 38-year-old told AFP.”They were helping him to find a university. And they were also helping him coach children. Those people were a key part of Emerson’s life,” Baquedano said.”What harm can a kid who plays soccer, attends church and goes to school do to a country?”Before emigrating to the United States, Baquedano sold bread on the street, but she is not yet sure how she will earn a living in Honduras this time.”Right now, I’m trying to come to terms with what happened, then start making a new life here,” she said.

US President Donald Trump was set to visit Texas on Friday as questions mounted over the response to flash floods that have left at least 120 people dead, including dozens of children.The Republican leader and First Lady Melania Trump will meet first responders and local officials in central Texas’s Hill Country, a week after heavy rainfall and an overflowing river swept away houses, trees, cars and people.They were due around midday in Kerrville, a city in the worst-affected Kerr County where at least 96 people died.”I would have done it today, but we’d just be in their way,” Trump told reporters when asked on Sunday about visiting the impacted communities.The urgent search for more than 170 missing people, including five girls who were at summer camp, entered the eighth day as rescue teams combed through mounds of debris and mud.But with no live rescues reported this week, worries have swelled that the death toll could still rise.Trump has brushed off questions about the impact of his cuts to federal agencies on the response to the flood, which he described as a “100-year catastrophe” that “nobody expected.”On Thursday, Homeland Security Department head Kristi Noem defended the immediate response as “swift and efficient.”But she previously said Trump wanted to “upgrade the technologies” of the “ancient” weather warning system.- FEMA questions -The floods, among America’s deadliest in recent years, have also reopened questions about Trump’s plans to phase out disaster response agency FEMA in lieu of greater state-based responsibility.FEMA began its response to the Texas flash floods over the weekend after Trump signed a major disaster declaration to release federal resources.But the president has so far avoided addressing questions about its future. Noem insisted FEMA should be “eliminated” in its current form at a government review meeting on Wednesday.Officials in Kerr County, which sits astride the Guadalupe River in an area nicknamed “Flash Flood Alley,” said at least 36 children were killed in the flash floods that struck at the start of the Fourth of July weekend.Details have surfaced about reported delays of early alerts at a local level that could have saved lives.Experts say forecasters did their best and sent out timely and accurate warnings despite the sudden weather change.White House Press Secretary Karoline Leavitt also defended National Weather Service (NWS) alerts as “early and consistent.”- Special session -Kerr County Sheriff Larry Leitha said “it was between 4:00 or 5:00 (am) when I got notified” of incoming emergency calls.ABC News reported Thursday that at 4:22 am on July 4, a firefighter in Ingram, upstream of Kerrville, had asked the Kerr County Sheriff’s Office to alert residents of nearby Hunt to the coming flood.The network said its affiliate KSAT obtained audio of the call, and that the first alert did not reach Kerr County’s CodeRED system for a full 90 minutes.In some cases, it said, the warning messages did not arrive until after 10:00 am, when hundreds of people had already been swept away by raging waters.The flooding of the Guadalupe River was particularly devastating for summer camps on its banks, including Camp Mystic, where 27 girls and counselors died. Five other Mystic campers and a counselor remain missing.Governor Greg Abbott has scheduled a special session of the Texas Legislature to discuss the disaster, beginning July 21. Kerrville Police Sergeant Jonathan Lamb said the session would be “a starting point” for reviewing ways to improve warning systems for weather events.

US President Donald Trump has announced a 50 percent tariff on Brazilian imports as he accused the country’s leftist leadership of orchestrating a “witch hunt” against his right-wing ally, former leader Jair Bolsonaro.In a letter Wednesday to counterpart Luiz Inacio Lula da Silva, Trump insisted that Bolsonaro’s trial — for allegedly plotting a coup to hold on to power after 2022 elections he lost — “should not be taking place.”Trump has historically reserved his tariff ire for countries with which the United States runs a negative trade balance. Brazil is not one.Analysts say ideological considerations, not economics, are behind the US president’s actions in defense of Bolsonaro, dubbed the “Trump of the Tropics.”- Firm friends -“Brazil came up on Trump’s radar now because Bolsonaro’s trial is advancing and there are Republican lawmakers who brought the issue to the White House,” Leonardo Paz, a political scientist at Brazil’s Getulio Vargas Foundation, told AFP. Eduardo Bolsonaro, the former president’s son and a Brazilian congressman, recently moved to the United States where he lobbies for pressure on Brasilia and the judges presiding over his father’s coup trial. Lula blames Bolsonaro’s son for troubling the bilateral waters, and Supreme Court Justice Alexandre de Moraes has ordered an investigation into whether the US-based campaign constitutes obstruction of justice.Moraes is an arch foe of Bolsonaro, who has labeled the justice a “dictator.”US Secretary of State Marco Rubio spoke in May of a “great possibility” of sanctions against Moraes, who has clashed repeatedly with rightwingers and former Trump ally Elon Musk in a quest to stamp out online disinformation.Bolsonaro calls Trump a “friend” and says they are both victims of “persecution.”- ‘Non-economic reasons’ -In his missive to Lula, Trump complained of “a very unfair trade relationship” with Brazil.But official Brazilian figures show a near two-decade sustained surplus in favor of the United States. Last year, it was almost $284 million.The United States is Brazil’s third-largest trading partner after China and the European Union. It imports mainly crude oil and semi-finished iron and steel products from the South American powerhouse.Brazil in turn primarily imports non-electric engines and machines, and fuel from up north.In a sign of Brazilian business jitters, the Sao Paulo Federation of Industries called Thursday for a “calm” response to the “non-economic reasons” for Trump’s tariffs.Lula has said Brazil would be willing to reciprocate, in spite of Trump’s warning of further escalation if it did so.- Free speech tussle -Trump also complained of Brazilian “attacks” on free speech and “hundreds of SECRET and UNLAWFUL censorship orders to US media platforms” issued by Brazil’s Supreme Court.Last month, the court toughened social media regulation, upping the accountability of platforms for user content in a groundbreaking case for Latin America on the spread of fake news and hate speech.Last year, Moraes blocked Musk’s X platform for 40 days for failing to comply with a series of court orders against online disinformation.He had also ordered the suspension in Brazil of Rumble, a video-sharing platform popular with conservative and far-right voices — including Trump’s son Don Jr. — over its refusal to block a user accused of spreading disinformation.Detractors accuse the judge of running a campaign to stifle free speech.- BRICS brawl -“It didn’t help that the BRICS summit was held in Brazil at a time a narrative exists in the United States portraying the bloc as anti-Western,” said Paz.Meeting in Rio de Janeiro, the group on Sunday spoke out against Trump’s “indiscriminate” tariff hikes, prompting the president to threaten further trade penalties.Members China, Russia and India refrained from hitting back, but Lula took it upon himself to defend the “sovereign” nature of BRICS governments, insisting: “We don’t want an emperor.”Behind the scenes, Brasilia has been negotiating with Washington for months to try and avoid the worst of Trump’s tariff war.A member of Lula’s entourage told AFP that Trump’s attack on Brazil was partly inspired by “discomfort caused by the strength of the BRICS,” whose members account for about half the world’s population and 40 percent of global economic output.
