The author argues that an open-weight release of Mythos would more likely accelerate cyber incidents than cause an abrupt leap in risk. That does not mean things will be “fine”: the software industry may face a costly transition requiring faster patching and more security work.
The article cites Epoch AI’s use of GLM-5.3 to find a Firefox vulnerability that could enable file exfiltration. The author says the example shows that harm requires further steps, such as an attacker setting up a suitable website, and stresses that these judgments remain uncertain.
Why it matters
The article distinguishes AI-assisted vulnerability discovery from real-world attacks and highlights the operational burden that rising disclosures may place on software teams.
Something to try
In a security review, list model-discovered vulnerabilities separately from the additional conditions needed to exploit them.
