Anthropic was forced by a US export-control directive to withdraw its Fable 5 and Mythos 5 models globally, impacting enterprises that relied on them for automation. This action occurred the same week that Z.ai released GLM-5.2, an open-weight model with a 1M-token context window that is downloadable and self-hostable.
