The balance between AI capability and AI safety just took a major step forward. Anthropic has officially released two new models: Claude Fable 5 and Claude Mythos 5. 🤖🔬

Fable 5 is designed for general use and sets a new standard for complex tasks like software engineering, vision, and deep knowledge work. However, because these frontier models pose significant dual-use risks, Anthropic has built in strict new safety classifiers. If a user asks Fable 5 a sensitive question about cybersecurity or biology, the system will automatically fall back and answer using the older Opus 4.8 model instead.

For the experts who actually need those advanced capabilities, Anthropic is offering Mythos 5. This model has the safeguards lifted but is restricted to a small, trusted group of cyberdefenders and life science researchers. It is a highly strategic approach to releasing powerful AI responsibly.
