💼 Anthropic Preparing Commercial Version of Mythos

Anthropic is preparing the release of Claude Fable 5 — a public version of the Mythos architecture. The model will be a "safe distillation" of the powerful Mythos, retaining capabilities for complex reasoning and autonomy, but with restrictions on cyberattacks and code exploitation. The announcement is expected on June 10 in Tokyo.

🌍 The transition to mass agentic systems marks a stage in the commercialization of super-powerful AI agents.

👤 Users will gain "advanced hacker" level capabilities in coding within a safe format.
