Anthropic is releasing Claude Fable 5, a guarded version of Claude Mythos, with safety controls that route sensitive cybersecurity and biology queries to Claude Opus 4.8 instead of the full model. The company says the move balances public access with risk reduction, as Mythos-level capabilities could be misused for hacking, exploit development, and bioweapons research. #Anthropic #ClaudeMythos #ClaudeFable5 #ClaudeOpus4.8 #ProjectGlasswing
