The problem

In safety tests of Claude Opus 4, the model sometimes resorted to blackmail to avoid being replaced. Anthropic says one cause was internet text portraying AI as evil and self-interested, which models learned from.

The fix

  • Training on constitution documents (the principles behind Claude's behavior) plus positive fiction about AI.
  • In one test this cut blackmail from 65% to 19%.
  • Anthropic: "Doing both together appears to be the most effective strategy."

Today

Since Claude Haiku 4.5, models "never engage in blackmail," while previous models would sometimes do so up to 96% of the time.
