This is a pure marketing stunt, OpenAI saw that it worked with Mythos and wanted to do the same.
Those instructions, according to OpenAI, called for using “complex attack paths” to test how well the AI could exploit a computer system. [...] “It went off and did this hack all by itself, as far as we can tell,” said Colin Shea-Blymyer, a cybersecurity research fellow at Georgetown University’s Center for Security and Emerging Technology.
Emphasis mine. So, the frontier model that has been tasked with attacking a system, did what it's been told to, after its safeguards that will prevent you from opening chatgpt and doing the same have been turned off.
OpenAI said the intrusion was caused by a combination of its AI models, including its newly released GPT‑5.6 Sol and an “even more capable” model that is still being tested internally.
Oh my god, an "even more capable" model? Let me buy OpenAI stock immediately. This is such an obvious bait and Antrophic move they're pulling off, it's amazing.
Nuclear fission has been used in nuclear reactors for good, and was exceedingly efficient at that time, and has been a significant factor in the recent human history. Just as it's been with the "evil" use in nuclear weapons.
I'm not aware of any breakthrough that has not been used for both good and evil.
