You have exactly **12 days** to test it for **FREE** on Pro plans before it goes pay-as-you-go. Don't miss out on this game-changing update!
Here’s everything you need to know about this major release:
📌 1. Built on the Same Foundation as Mythos 5
Fable 5 is based on the same core architecture as Anthropic's highly restricted Mythos 5 model. However, it includes additional, robust safeguards making it perfectly suitable for general public use, combining power with responsibility.
📌 2. Huge Performance Boost in Critical Areas
According to Anthropic, Fable 5 delivers major improvements in:
* Software Engineering
* Complex Reasoning
* Knowledge Work
* Long-running Projects
* Visual Understanding
It was specifically designed for difficult, sustained tasks that require deep thinking and complex ex*****on.
📌 3. Advanced, Automatic Safety Layer
This is one of the biggest reasons Anthropic felt comfortable making the model available. When users enter high-risk areas, like advanced cybersecurity or biological research, Fable 5 can automatically restrict responses and defer to safer, dedicated models.
📌 4. Available EVERYWHERE You Work
Fable 5 is already rolling out through:
* Claude.ai
* The Claude API
* Enterprise offerings
* GitHub Copilot
