The Model That Shipped and the One That Didn't

Two Anthropic stories this week are really one story told from opposite ends. Opus 4.7 shipped with real-time cyber safeguards explicitly described as a testbed for what Anthropic hopes to eventually do with Mythos-class models — the model they restricted last week after it autonomously chained zero-days across major OSes and browsers. Read together, the launch post reads less like a capability announcement than an operational admission: we can now ship a model only because we have learned to differentially suppress parts of it at training time and intercept prohibited use at inference time. "Same pricing as 4.6, state-of-the-art on CursorBench" is the surface; the sub-narrative is that the frontier now routinely produces capabilities that need to be partially unlearned before release.
