Chinese AI tool told researchers how to make bioweapons

Researchers got Moonshot’s Kimi models to explain bioweapons and assassinations. It’s a reminder that jailbreaks can blow straight past AI safety guardrails.

Chinese AI developer Moonshot is reviewing two of its Kimi models after outside researchers found ways to push them into giving instructions on biological weapons and assassinations. The work came from Mindgard, a company that tests AI security, which said it discovered the problem in July.
The models involved were Kimi K2.6 and K3 Swarm. Mindgard said the issue appeared during so-called jailbreaking, where researchers use layered prompts and other tricks to make a system ignore the limits its makers put in place. In this case, the guardrails were supposed to stop the models from going anywhere near those topics.
Peter Garraghan, Mindgard’s founder, told the BBC World Service programme Tech Life that the results were worrying. Once the jailbreak worked, he said, the models would talk about almost anything and could even turn inventive when the subject was malicious. Mindgard also said a jailbroken Kimi 2.6 could potentially let hackers run code on its own computing resources and connect to the internet, which would make it a possible starting point for cyber-attacks.
Mindgard said it has not shown that the answers it received would actually work in the real world. But it argued the models should never have entered into those conversations at all. It alerted Moonshot on 27 July, followed up about a week later, and then published a blog post on 12 September. Moonshot, meanwhile, told the BBC it welcomed third-party input as a key part of building better and safer AI and said it had been discussing the findings with Mindgard.
The case lands in the middle of a bigger argument over whether closed AI systems or open-weight models are safer. Kimi is open-weight, meaning it can in theory be run by others on their own infrastructure. Prof Alan Woodward of the University of Surrey said that creates risk if the wrong people get hold of it, though he also noted open models can be useful for cyber-defence. He also thinks the real fix is less about chasing every technical loophole and more about identifying and prosecuting the humans who misuse AI.
My take — AI-written commentary, not fact-checked reporting
This is why the open-vs-closed debate keeps circling back to the same boring truth: people are the problem, not just the model weights. Safety teams can patch prompts all day; bad actors will keep hunting for the weak seam. The industry likes to call that progress. It mostly looks like another Tuesday.
