Anthropic releases dual-access Claude models, emphasizing safety controls

By PulseAugur Editorial · [1 sources] ·

Anthropic has released two versions of the same underlying model, Claude Fable 5.1 and Claude Mythos 5.1, differentiating them through distinct safety boundaries and access controls. This approach shifts the focus from raw capability benchmarks to how different user groups can access and utilize the model under varying levels of supervision. The Mythos version, intended for higher-risk applications like cybersecurity and biology, demonstrated significant advancements, including a nearly 50% protein-binder hit rate and substantial speedups in deep-learning models.

IMPACT This release highlights a new product strategy for frontier models, where differentiated safety and access controls are as crucial as raw performance.

    Anthropic ships the same model behind two different safety boundaries

    <p>Anthropic says Claude Fable 5.1 and Claude Mythos 5.1 are the same underlying model with different safeguards and access. That makes the release a test of how a frontier company can expose capability selectively, rather than a familiar contest over whose new weights score high…
