Intern allegedly messed with ByteDance's LLM training cluster

ByteDance has terminated an intern for "maliciously interfering" with a large language model training project.

The parent company of TikTok addressed rumors that had been circulating around the internet in a statement it posted on its news aggregation platform Toutiao.

"Recently, some media said that 'ByteDance's large model training was attacked by interns', and after internal verification by the company, there were indeed serious violations of discipline ... in the commercial technical team, and the intern has been dismissed," wrote ByteDance as auto-translated from Chinese.

The Chinese giant denied claims that the intern disrupted training on a cluster of over 8,000 H100 GPUs and caused tens of millions of dollars in losses.

The page - which The Reg will not link to as it names the accused man - claims that the student carried out his attack for over two months, "causing great harm to nearly 30 employees at all levels of the company and making your colleagues' work in vain for nearly a quarter."
