“that’s why we chose not to release our latest model widely due to concerns about cyber misuse.”
Daniela Amodei, Anthropic president 9 May 2026 Daniela Amodei, Co-Founder and President of Anthropic: Building AI the Right Way (transcript) (The Transcript Desk)
Anthropic chose not to release its latest model widely because of concerns about cyber misuse.
Mostly true True in substance, wrong in a detail.
The second judge said resolved true; the verdict shown is the first judge's.
Said for an organisation they lead or work for; it counts on both records.
What would count as true or false
Judged as of 2026-05-09. True: Anthropic's official announcements show that, as of that date, its most recent frontier model was withheld from broad or general release (for example limited to restricted partners) and that cyber misuse or cybersecurity risk was given as a reason. Mostly true: the restriction and the cyber-misuse reason are documented, but a minor detail is off (for example cyber was one of several stated reasons, or the model was not strictly the latest). Mixed: the model was restricted, but the stated reasons were mainly something other than cyber misuse, with cyber only incidental. Mostly false: the release was only briefly staged or delayed, or the restriction concerned a different model, which distorts the claim. False: Anthropic's latest model as of that date was released widely, with no restriction tied to cyber concerns.

“We do not plan to make Claude Mythos Preview generally available, but our eventual goal is to enable our users to safely deploy Mythos-class models at scale—for cybersecurity purposes, but also for the myriad other benefits that such highly capable models will bring.”

“Claude Mythos’s large increase in capabilities has led us to decide not to make it generally available. Instead, we are using it as part of a defensive cybersecurity program with a limited set of partners.”

“Anthropic has chosen to restrict access and work with a small group of trusted partners, rather than releasing the model broadly.”
Reasoning
Anthropic's Project Glasswing announcement says it does not plan to make Claude Mythos Preview generally available, and that the project was formed because of a new frontier model's capabilities that could reshape cybersecurity (E1, E2). Independent reports confirm that access was limited to a small set of trusted partners in a defensive cybersecurity program rather than released broadly (E3, E4). The restriction and its link to cybersecurity are documented. However, the quoted rationale points to the model's "large increase in capabilities" rather than naming cyber misuse alone. The evidence also does not strictly confirm that Mythos was still Anthropic's latest model on 2026-05-09.
