Keir Starmer should pledge £11bn towards building "BritGPT" and a national artificial intelligence (AI) cloud in the next Labour manifesto or risk the UK falling ever further into dependence on American tech companies, an affiliated thinktank has said. Labour for the Long Term, which campaigns within the party for it to adopt "long-termist" policies that mitigate dangers such as pandemics, climate breakdown, and AI extinction, argues in a report that the £1bn pledged by the government in the 2023 budget is not enough to protect Britain's future independence. The report calls for the creation of BritGPT, a homemade system with a remit to focus on market failures rather than simply trying to compete with Silicon Valley to build the biggest models. "Private profit-seeking companies aren't going to invest enough in'AI for good' or AI safety, so the UK government should step in to correct this market failure and provide more public goods – such as medical research, clean energy research, and AI safety research," it said. They suggested some of the budget could even come out of Labour's £28bn annual "climate investment pledge" as a result.

The UK government is to invest £900m in a cutting-edge supercomputer as part of an artificial intelligence strategy that includes ensuring the country can build its own "BritGPT". The treasury outlined plans to spend around £900m on building an exascale computer, which would be several times more powerful than the UK's biggest computers, and establishing a new AI research body. An exascale computer can be used for training complex AI models, but also have other uses across science, industry and defence, including modelling weather forecasts and climate projections. The Treasury said the £900m investment will "allow researchers to better understand climate change, power the discovery of new drugs and maximise our potential in AI.". An exascale computer is one that can carry out more than one billion billion simple calculations a second, a metric known as an "exaflops".

The UK needs to support the creation of a British version of ChatGPT, MPs were told on Wednesday, or the country would further lose the ability to determine its own fate. Speaking to the Commons science and technology committee, Adrian Joseph, BT's chief data and artificial intelligence officer, said the government needed to have a national investment in "large language models", the AI that underpins services such as ChatGPT, Bing Chat and Google's Bard. Without such technology, the nation would struggle to compete internationally in future, he said. "We think there's a risk that we in the UK, lose out to the the large tech companies, and possibly China, and get left behind … in areas of cybersecurity, of healthcare, and so on. It is a massive arms race that has been around for some time, but the heat has certainly been turned up most recently."
