China is closing in on the US in the AI race after the superpower developed its cybersecurity capabilities to match those of American tech firm Anthropic. 

Beijing-based tech firms 360 Security Technology and Z.ai, also known as Zhipu AI, have narrowed the gap with the US competitor when it comes to finding bugs. 

360 Security Chief Executive Zhou Hongyi told a cybersecurity conference in the Chinese capital that the company's bug-finding tool, called Tulongfeng, is now comparable to Anthropic's Mythos, which serves the same function. 

'This kind of powerful weapon that can alter the landscape of cyberwarfare can't remain solely in American hands,' Zhou told the conference, according to the Wall Street Journal. 

Though Chinese tech is advancing in this field, it still lags behind on other fronts, including OpenAi products which are also part of Anthropic's armory. 

It comes as the AI race between China and the US has reached boiling point. 

Donald Trump's administration has been imposing limits on public access to new models due to security concerns, while China has been closing the gap in the race to develop the world's most advanced AI systems. 

'Our administration is very much focused on Chinese open-source models,' Jacob Helberg, who is undersecretary of state for economic affairs and a former tech adviser and investor, told the WSJ. 

'It's something that we're tracking very closely.' 

While Donald Trump and Chinese President Xi Jinping have maintained what the President terms a 'good relationship,' the rivalry between the two superpowers remains tense.   

ChatGPT maker OpenAI said Friday it is restricting the release of its new artificial intelligence model at the request of the Trump administration, the latest in an unprecedented government vetting of AI products for cybersecurity risks.

Its chief rival, Anthropic, announced hours later that the Trump administration has approved a limited release of its strongest cybersecurity model, two weeks after the Commerce Department effectively banned it.

Both companies said their newest models would be available to small groups of trusted partners. OpenAI said its new AI product, called GPT-5.6 Sol, would be accessible only to customers approved by the Trump administration.

'We don´t believe this kind of government access process should become the long-term default,' OpenAI said in a statement. The company said it viewed the testing period as a temporary step on the 'path to broader availability in the coming weeks.'

OpenAI's staggered release of a powerful new AI system follows actions the government took earlier this month against Anthropic, maker of the Claude chatbot.

Anthropic took offline two new AI models, known as Fable 5 and Mythos 5, just days after unveiling them to comply with a Trump directive blocking their use by foreign nationals. 

The government on Friday lifted restrictions on one of those models, Mythos 5, enabling it to be 'redeployed to a small group of cyber defenders and infrastructure providers,' Anthropic said.

The White House said Friday it continues to collaborate with frontier AI labs on addressing the challenges of scaling the fast-growing technology.

The Daily Mail has reached out to the White House for comment. 

Officials have grown increasingly concerned since Anthropic warned earlier this year that its Mythos model was adept at finding software flaws in a way that could be weaponized by malicious hackers and threaten critical computer networks around the world.

Trump earlier in June signed an executive order on AI oversight that established a framework for the federal government to vet the national security risks of the most advanced AI systems for up to 30 days before their public release. 

The order described participation by AI developers as voluntary but the framework has not yet been fully developed.

Some of Trump´s allies have laid blame on San Francisco-based Anthropic and CEO Dario Amodei for the need for heightened government scrutiny.

'Dario came to Washington a few months ago, back in April, and basically said that he had created a cyber weapon called Mythos,' said investor David Sacks, who co-leads Trump´s council of technology and science advisers, on a recent podcast. 

'And he spiked the cortisol level, got everyone really worried. And there was some truth to it in terms of the sense that this model had advanced cyber capabilities.'

OpenAI, also based in San Francisco, said its new Sol model 'is better at helping people find and fix vulnerabilities' than it is at carrying out cyberattacks and does not cross the company´s own risk threshold. 

But it acknowledged there could be unforeseen risks especially if its model is combined with other tools.

'That uncertainty, along with the model´s broader step change in capabilities, is why we are pairing the model´s increased capabilities with stronger safeguards and a phased release,' the company said Friday.

OpenAI hasn't named any of the roughly 20 customers that have been approved to use the new model so far.

U.S. Rep. Lori Trahan, a Massachusetts Democrat and co-author of a bipartisan bill that would regulate AI, said in a statement that she is concerned 'the Trump administration is deciding company by company who gets access to the newest AI model. No law. No process. No oversight. Just appointees in Washington deciding who´s in and who´s out.'
