The owner of Facebook has announced plans to make its version of the artificial intelligence technology behind ChatGPT free for researchers and companies to use.
The latest version of Meta’slarge language model, called LLaMa 2, will rival OpenAI’s GPT-4, which powers the chatbot app.
The technology came to the fore last November after the release of ChatGPTbuilt a user base of 100 million in just two months.

Meta said in a news release that it decided to open up access to LLaMa 2 so businesses and researchers could access more AI tools and use them to experiment.
LLaMa 2 is the second generation of Meta’s large language model, which was first announced in February.
The second version of the model is trained on 40% more data compared with LLaMa 1, according to Meta.
Artificial intelligence has been around for decades and is used in satellite navigation systems and virtual assistants like Siri, but large language models have ushered in a new era of generative AI.

AI now fluent in human language
The development of regulation to ensure companies are transparent about how their AI is trained and guard against misinformation and bias is still in the early stages across the world.

After the launch of ChatGPT last year, Google responded with Bard, a search engine powered by artificial intelligence, and Microsoft launched its own version called BingChat.
Unlike the models developed by OpenAI and Google, Meta is making LLaMa 2 open source, which means the code is freely available to download and modify.

Meta said in a statement on Tuesday night: “We believe an open approach is the right one for the development of today’s AI models, especially those in the generative space where the technology is rapidly advancing.
“Opening access to today’s AI models means a generation of developers and researchers can stress test them, identifying and solving problems fast, as a community.”
The model will be available through Microsoft’s cloud computing platform, Azure, as well as Hugging Face and Amazon Web Services.
Mark Zuckerberg, chief executive of Meta, said in a post on Facebook: “Open-source drives innovation because it enables many more developers to build with new technology … I believe it would unlock more progress if the ecosystem were more open, which is why we’re open-sourcing LLaMa 2.”
Oli Buckley, a professor of cybersecurity at the University of East Anglia, said it is important to improve our understanding of AI before making source code publicly available.
“Every significant technological innovation in the last 100 years has had some capacity for misuse, with no shortage of people ready and willing to actually misuse it,” he explained.
“The difference between a nuclear weapon and a [large language model] is that we are at least able to identify people procuring the pieces they need to make a nuclear weapon, it’s much harder to identify who is exploiting AI for something untoward.”
Donald Trump could meet Vladimir Putin in person as early as next week to discuss a ceasefire in Ukraine, a White House official has said.
They said the meeting would be conditional on the Russian president meeting his Ukrainian counterpart Volodymyr Zelenskyy, Sky News’s US partner network NBC News reported.
It came days before the White House’s deadline for Russia to reach a peace deal with Ukraine or face severe economic penalties, which could also target countries buying its oil.
Asked during a news conference at the White House if the talks would take place, Mr Trump said: “There’s a very good prospect that they will.”
He said it had not been determined where the talks would take place, but added: “We had some very good talks with President Putin today.”
However, he said: “I’ve been disappointed before with this one.”
Asked if Mr Putin made any kind of concession to lead to the development, Mr Trump did not give much away, but added: “We’ve been working on this a long time. There are thousands of young people dying, mostly soldiers, but also, you know, missiles being hit into Kyiv and other places.”
Trump might finally be a step closer to ending the war
Seven hours is a long time in US politics.
At 10am, Donald Trump accused Russia of posing a threat to America’s national security.
At 5pm, Trump said there was a “good prospect” of him meeting Vladimir Putin “soon”.
There had, he claimed, been “great progress” in talks between his special envoy Steve Witkoff and the Russian president.
It’s difficult to gauge the chances of a meeting between the two leaders without knowing what “great progress” means.
Is Russia “inclined” towards agreeing a ceasefire, as Ukraine’s president now claims?
Is Putin prepared to meet with his Ukrainian foe Volodymyr Zelenskyy, too?
The very fact that we’re asking those questions suggests something shifted on a day when there was no expectation of breakthrough.
Trump repeatedly vowed to end the war within 24 hours of becoming president.
On day 198 of his presidency, he might, just might, be one step closer to achieving that.
More tariffs ‘could happen’
Mr Trump also said he could announce further tariffs on China similar to the 25% he announced on India over its purchases of Russian oil.
“Could happen,” he said, after saying he expected to announce more secondary sanctions intended to pressure Russia into ending its war with Ukraine.
Earlier, he imposed an additional 25% tariff on Indian goods, on top of a previous 25% tariff, over its continued purchases of Russian oil.
India’s foreign ministry spokesperson said the additional tariffs were “unfair, unjustified and unreasonable”.

It came after Mr Putin held talks with Mr Trump‘s special envoy Steve Witkoff in Moscow, with the meeting lasting around three hours.
In a post on Truth Social, Mr Trump said Mr Witkoff “had a highly productive meeting” with Mr Putin in which “great progress was made”.
He said he had updated America’s European allies, and they will work towards an end to the Russia-Ukraine war “in the days and weeks to come”.

‘The war must end’
Mr Zelenskyy later said he and Mr Trump spoke on the phone after the meeting. He said “European leaders also participated in the conversation” and “we discussed what was said in Moscow”.
He added: “Our common position with our partners is absolutely clear: The war must end. We all need lasting and reliable peace. Russia must end the war that it started.”
Mr Zelenskyy later said: “It seems that Russia is now more inclined to agree to a ceasefire.”
He added that the pressure on Moscow “is working”, without elaborating, and stressed it was important to make sure Russia does not “deceive us or the United States” when it comes to “the details” of a potential agreement.
Five soldiers have been injured in a shooting at an army base in the US – with authorities placing the location in “lockdown”.
“The installation was locked down at 11.04am and law enforcement is on the scene,” the Fort Stewart base in Georgia wrote on Facebook.
It said the incident took place at the 2nd Armoured Brigade Combat Team area and casualties had been reported.
The gunman has been arrested and there is “no active threat to the community”, the base added.
“The incident remains under investigation and no additional information will be released until the investigation is complete,” it said. The lockdown was lifted at 12.10pm local time.

Fort Stewart is around 25 miles (362km) southeast of Atlanta and is the largest US Army base east of the Mississippi River. It houses thousands of soldiers assigned to the army’s 3rd Infantry Division and their family members.
The fort’s three schools, which have nearly 1,400 students, were also placed under lockdown. Three schools outside the base also took steps similar to a lockdown “out of an abundance of caution”.

America’s vaccine-sceptic health secretary has announced $500m (£375.8m) worth of cuts to their development in the country.
The US health department is cancelling contracts and pulling funding for jabs to fight viruses like COVID-19 and the flu, it was announced on Tuesday.
Robert F Kennedy Jr, known as RFK Jr, said 22 projects developing mRNA vaccines will be halted. It is the latest in a series of decisions to reduce US vaccine programmes.
The health secretary has fired the panel that makes vaccine recommendations, reduced recommendations for COVID-19 shots, and refused to endorse vaccines despite a worsening measles outbreak.
RFK Jr claims the US will now prioritise “safer, broader vaccine strategies, like whole-virus vaccines and novel platforms that don’t collapse when viruses mutate”.
Responding to the announcement of cuts, Mike Osterholm, a University of Minnesota expert on infectious diseases and pandemic preparations, said: “I don’t think I’ve seen a more dangerous decision in public health in my 50 years in the business.”

Is US politics fuelling a deadly measles outbreak?
Dr Paul Offit, a vaccine expert at Children’s Hospital of Philadelphia, said RFK Jr’s move was short-sighted and that mRNA vaccines “certainly saved millions of lives”, including during the pandemic.
MRNA vaccines work by delivering a snippet of genetic code into the body that triggers an immune response, rather than introducing a real version of the virus.
According to the UK Health Security Agency, the “leading advantage of mRNA vaccines is that they can be designed and produced more quickly than traditional vaccines”.
Moderna, which was studying a combo mRNA shot that can tackle COVID and flu for the US health department, previously said it believed mRNA could speed up production of flu jabs compared with traditional vaccines.
