However, this has not yet appeared to slow the appetite to invest in AI firms – there are reports that OpenAI is in talks to raise around 40 billion dollars (£31.7 billion) in a new funding round which would push its valuation up to around 300 billion dollars (£238 billion).
Mr Musk has previously filed two lawsuits against OpenAI, claiming it has strayed from its founding principles of being a non-profit, and last week launched a bid to buy the company for 97.4 billion US dollars (£77.3 billion) – a bid that was rejected by Mr Altman and the OpenAI board.
Meanwhile, it has been reported that xAI is in talks to raise around 10 billion dollars (£8 billion), which would value the firm at around 75 billion dollars (£59.5 billion).
The AI start-up confirmed Grok 3 will be made available to Premium+ subscribers on X – the social media platform also owned by Mr Musk – and will also be part of a new subscription called SuperGrok which will include access via the Grok mobile app and website.
Mr Musk said Grok 3 is the “smartest AI on Earth”, and the company said it performed better in benchmark tests across science, maths and coding than ChatGPT, as well as Google’s Gemini, DeepSeek and Anthropic’s Claude.
