Claude's creators changed a policy to be more open about how their new Fable 5 model can be used by others, especially if someone tries to build another AI with it.

Anthropic is backtracking on a policy that would have covertly limited competitors from using its new AI model, Claude Fable 5, to develop other AI models.
