Claude Fable 5.1 cuts token pricing by 75%
Anthropic has just released significant updates to its powerful coding science models, introducing two distinct versions: Fable 5.1 and Mythos 5.1. These releases highlight Anthropic’s ongoing commitment to balancing powerful AI capabilities with essential safety and access protocols.
The Fable 5.1 version is the broadly available offering. This iteration comes equipped with robust safeguards designed to prevent the generation of certain high-risk material. These restrictions are specifically put in place to mitigate potential misuse in sensitive fields such as cybersecurity and scientific research, ensuring that the technology remains a responsible tool for the community.
For users seeking access to more unrestricted capabilities, Anthropic has also introduced Mythos 5.1. This version operates with fewer of the restrictions found in Fable 5.1, offering a different level of access to the model’s potential. However, this enhanced access is strictly managed. Use of Mythos 5.1 is limited exclusively to participants within Anthropic’s trusted-access program, underscoring a commitment to controlled and vetted deployment.
