China’s DeepSeek trained AI model on Nvidia’s best chip despite US ban, official says

  • DeepSeek could remove technical indicators showing use of US chips, official says
  • US export ‌controls bar Blackwell shipments to China

WASHINGTON: Chinese AI startup DeepSeek’s latest AI model, ​set to be released as soon as next week, was trained on Nvidia’s most advanced AI chip, the Blackwell, a senior Trump administration official said on Monday, in what could represent a violation of US export controls.
The US believes DeepSeek will remove the technical indicators that might reveal its use of American AI chips, the official said, adding that the Blackwells are likely clustered at its data center in Inner Mongolia, an autonomous region of China.
The person declined to say how the US government received the information or how DeepSeek obtained the chips, but emphasized that US policy ‌is :“we’re not shipping ‌Blackwells to China.”
Nvidia declined to comment, while the Commerce Department and ​DeepSeek ‌did ⁠not respond ​to ⁠requests for comment.
The Chinese embassy in Washington said Beijing opposes “drawing ideological lines, overstretching the concept of national security, expansive use of export controls and politicizing economic, trade, and technological issues.”
The news, not previously reported, could further divide Washington policymakers as they struggle to determine where to draw the line on Chinese access to the crown jewels of American AI semiconductor chips.
China hawks fear chips could easily be diverted from commercial uses to help supercharge China’s military and threaten US dominance in AI.
But White House AI ⁠Czar David Sacks and Nvidia CEO Jensen Huang argue that shipping advanced ‌AI chips to China discourages Chinese competitors like Huawei ‌from redoubling efforts to catch up with Nvidia’s and AMD’s technology.
US ​export controls, overseen by the Commerce Department, currently ‌bar Blackwell shipments to China.
In August, US President Donald Trump opened the door to Nvidia ‌selling a scaled-down version of the Blackwell in China. But he later reversed course, suggesting the firm’s most advanced chips should be reserved for US companies and kept out of China.
Trump’s decision in December to allow Chinese firms to buy Nvidia’s second most advanced chips, known as the H200, drew sharp criticism from China ‌hawks, but shipments of the chips remain stalled over guardrails built into the approvals.
“Chinese AI companies’ reliance on smuggled Blackwells underscores their massive ⁠shortfall of domestically produced ⁠AI chips and why approvals of H200 chips would represent a lifeline,” said Saif Khan, who served as director of technology and national security at the White House’s National Security Council under former President Joe Biden.
The official declined to comment on how the latest news would impact the Trump administration’s decision on whether to allow DeepSeek to buy H200s.
The model they helped train likely relied on the “distillation” of models made by leading-edge US AI companies, including Anthropic, Google, OpenAI, and xAI, echoing allegations made by OpenAI and Anthropic, the official added.
The technique known as distillation involves having an older, more established and powerful AI model evaluate the quality of the answers coming out of a newer model, effectively transferring the older model’s learnings.
Hangzhou-based DeepSeek shook markets early last ​year with a set of AI models that ​rivaled some of the best offerings from the US, fueling concerns in Washington that China could catch up in the AI race despite restrictions.


Afghanistan says it thwarted Pakistani airstrike on Bagram Air Base as fighting enters fourth day

Afghanistan says it thwarted Pakistani airstrike on Bagram Air Base as fighting enters fourth day

  • The fighting has been the most severe between the neighbors for years
  • Pakistan accuses Taliban government of harboring militant groups that stage attacks against it

KABUL: Afghanistan thwarted attempted airstrikes on Bagram Air Base, the former US military base north of Kabul, authorities said Sunday, while cross-border fighting between Pakistan and Afghanistan stretched into a fourth day.
The fighting has been the most severe between the neighbors for years, with Pakistan declaring that it’s in “open war” with Afghanistan.
The conflict has alarmed the international community, particularly as the area is one where other militant organizations, including Al-Qaeda and the Daesh group, still have a presence and have been trying to resurface.
Pakistan accuses Afghanistan’s Taliban government of harboring militant groups that stage attacks against it and also of allying with its archrival India.
Border clashes in October killed dozens of soldiers, civilians and suspected militants until a Qatari-mediated ceasefire ended the intense fighting. But several rounds of peace talks in Turkiye in November failed to produce a lasting agreement, and the two sides have occasionally traded fire since then.
On Sunday, the police headquarters of Parwan province, where Bagram is located, said in a statement that several Pakistani military jets had entered Afghan airspace “and attempted to bomb Bagram Air Base” at around 5 a.m.
The statement said Afghan forces responded with “anti-aircraft and missile defense systems” and had managed to thwart the attack.
There was no immediate response from Pakistan’s military or government regarding Kabul’s claim of attempted airstrikes on Bagram or the ongoing fighting.
Bagram was the United States’ largest military base in Afghanistan. It was taken over by the Taliban as they swept across the country and took control in the wake of the chaotic US withdrawal from the country in 2021. Last year, US President Donald Trump suggested he wanted to reestablish a US presence at the base.
The current fighting began when Afghanistan launched a broad cross-border attack on Thursday night, saying it was in retaliation for Pakistani airstrikes the previous Sunday.
Pakistan had said its airstrike had targeted the outlawed Pakistani Taliban, also known as Tehreek-e-Taliban Pakistan, or TTP. Afghanistan had said only civilians were killed.
The TTP militant group, which is separate but closely allied with Afghanistan’s ruling Taliban, operates inside Pakistan, where it has been blamed for hundreds of deaths in bombings and other attacks over the years.
Pakistan accuses Afghanistan’s Taliban government of providing a safe haven within Afghanistan for the TTP, an accusation that Afghanistan denies.
After Thursday’s Afghan attack, Pakistani Defense Minister Khawaja Mohammad Asif declared that “our patience has now run out. Now it is open war between us.”
In the ongoing fighting, each side claims to have killed hundreds of the other side’s forces — and both governments put their own casualties at drastically lower numbers.
Two Pakistani security officials said that Pakistani ground forces were still in control on Sunday of a key Afghan post and a 32-square-kilometer area in the southern Zhob sector near Kandahar province, after having seized it during fighting Friday. The captured post and surrounding area remain under Pakistani control, they added. The officials spoke on condition of anonymity, because they weren’t authorized to speak publicly.
In Kabul, the Afghan government rejected Pakistan’s claims. Deputy government spokesman Hamdullah Fitrat called the reports “baseless.”
Afghan officials said that fighting had continued overnight and into Sunday in the border areas.
The police command spokesman for Nangarhar province, Said Tayyeb Hammad, said that anti-aircraft missiles were used from the provincial capital, Jalalabad, and surrounding areas on Pakistani fighter jets flying overhead Sunday morning.
Defense Ministry spokesman Enayatulah Khowarazmi said that Afghan forces had launched counterattacks with snipers across the border from Nangarhar, Paktia, Khost and Kandahar provinces overnight. He said that two Pakistani drones had been shot down and dozens of Pakistani soldiers had been killed.
Fitrat said that Pakistani drone attacks hit civilian homes in Nangarhar province late Saturday, killing a woman and a child, while mortar fire killed another civilian when it hit a home in Paktia province.
There was no immediate response to the claims from Pakistani officials.
