Svmuu reported that tech journalist Alex Heath posted on X platform, stating that Anthropic plans to release a public version of Mythos tomorrow. They will rename and slightly adjust Mythos, releasing it under the name "Fable 5." This version will have strict safety measures and will not be as lenient with network operations as the version accessible to Project Glasswing partners. Meanwhile, its performance in long-cycle, multi-turn tasks will be significantly improved.
