Anthropic’s new Fable release is cheaper, less restrictive
Anthropic has released Fable 5.1 and Mythos 5.1, updated AI models that offer improved performance and reduced costs. The release includes a high-privacy 'Zero Data Retention' feature for enterprise clients and maintains strict access controls for sensitive research sectors.
Why it matters
As AI models become more powerful, the balance between accessibility, cost-efficiency, and data security remains a critical challenge for enterprise adoption.
On Tuesday, Anthropic released Fable and Mythos 5.1, twinned versions of the company’s most advanced AI model. In addition to performance upgrades, the new Fable release includes changes meant to reduce token cost and false-positive restrictions from the model’s safeguards.
As with the previous Mythos model, Mythos 5.1 will only be available to registered Anthropic partners engaged in either cybersecurity or life sciences research. Fable 5.1, the unrestricted version, is available starting today on cloud platforms or through the Anthropic API.
