Anthropic Mythos: Unreleased Model Reportedly More Powerful Than Opus 4.7
Anthropic Mythos — Anthropic's most powerful model — has not been released to the public. Reports indicate it's only being shown privately to leading technology and financial infrastructure companies so they can address security implications before public release.
If true, Mythos represents a category-shift in capability requiring infrastructure-level security review before broad release. This is the first time Anthropic has held back a model on safety grounds at this scale. Public release timeline unknown.
No public access yet. Watch anthropic.com/news for the release announcement. Expected within 6 months based on the Google deal funding cadence.
Mythos is one factor cited by analysts arguing Anthropic’s $350B valuation is too low. Combined with $30B annualized revenue (3x growth in 4 months) and the upcoming IPO, the unreleased model represents pent-up future revenue not yet captured in current numbers.
