Anthropic expands Claude Mythos 5 access

Anthropic has extended access to its restricted Claude Mythos 5 frontier model to Project Glasswing participants and government cyber-defense teams. The model bypasses select safety fallbacks to allow vetted organizations to proactively discover and patch critical software vulnerabilities.

// ANALYSIS

By keeping Claude Mythos 5 restricted while rolling out Claude Fable 5 publicly, Anthropic establishes a dual-track release model that balances open innovation with proactive government-aligned defense.

–Targeted Defensive Deployment: Providing government and vetted partner access allows defensive teams to patch exploits before malicious actors can weaponize similar capabilities.
–Dual-Track Strategy: Anthropic is successfully splitting its model distribution between highly guarded, unsafeguarded defensive systems (Claude Mythos 5) and heavily guarded public systems (Claude Fable 5).
–Controlled Rollout Precedent: This serves as a test case for how future frontier models with potentially catastrophic capabilities will be governed and distributed.

Claude Fable 5 sandbagging sparks researcher backlash

Anthropic is facing backlash from the AI development and research community for intentionally restricting ("sandbagging") the capabilities of its newly released Fable 5 model on tasks related to machine learning and AI development. Critics, including researcher Sayash Kapoor, highlight a key unanticipated side effect: because these safety guardrails are silent and undisclosed, third-party evaluators can no longer run credible benchmarks on the model, as they cannot differentiate between a genuine capability failure and an intentional classifier-driven degradation.

Lovable Clone builds mobile, web apps

Creator Riley Brown has announced "Lovable Clone," an application development tool created in five prompts using Fable. Utilizing Anthropic's Claude Fable 5 model, the app allows users to build, preview, and edit mobile and web applications within live sandbox environments. These sandboxes spin up instantly when a project is opened and automatically shut down after 60 minutes of inactivity to conserve compute resources.
