The model will reportedly be made available to enterprise customers and paid subscribers.
Just two months after rolling out Mythos to a limited pool of high-level users, Anthropic has announced the release of Claude Fable 5, an AI model similar to Mythos but with significant safeguards and blocks to prevent deliberate misuse and security breaches, according to the company.
Unlike Mythos, which is currently only available to a select number of organisations and institutions due to major concerns about securing critical infrastructure, Claude Fable 5 will be made available to enterprise customers and paid subscribers.
The model has built-in barriers that aim to block responses in high-risk areas such as cybersecurity, chemistry and biology, with such interactions automatically handled instead, the company said, by its Opus 4.8 model.
Fable 5, Anthropic claimed, shows strong capabilities in software engineering, knowledge work, vision, scientific research and similar fields.
