Anthropic has released Claude Fable 5, a Mythos-level AI model with built-in safeguards designed to route certain high-risk prompts to older models instead. As AI capabilities continue to accelerate, are AI companies creating systems they no longer fully trust? We discuss AI safety, prompt routing, technical debt, and whether this approach can scale as future models become even more powerful.
As AI gets more powerful, it seems that it’s also becoming less safe. A few weeks ago we covered Project Glasswing - a cybersecurity initiative launched by Anthropic due to safety concerns surrounding the Claude Mythos Preview. Today we’re discussing the recent public release of Claude Fable 5 - a Mythos level AI model. With many security concerns still in-hand, Fable 5 has been equipped with safeguards that should help keep worrisome prompts from using this latest model, instead opting for the older Claude Opus 4.8.
