Anthropic stops testing new Mythos model after unreleased ‘Oceanus’ leak

Anthropic is raising the alarm about recursive self-improvement, warning that accelerated updates could quickly spiral past human control. Anthropic’s internal metrics back it up. Claude now writes over 80% of the company’s production code, triggering a massive 8x explosion in developer output. 

On one end, cybersecurity is fundamentally breaking. Anthropic’s Logan Graham says AI is now finding flaws faster than organizations can patch them, making remediation the key constraint. He also predicts today’s leading cyber models could look “dumb” within 6–12 months. 

This raw power is already being weaponized: Financial Times has reported that NSA has embedded half a dozen forward-deployed Anthropic engineers to help the agency deploy Claude Mythos for offensive cyber operations, using its advanced exploit-detection capabilities to plan strategic strikes despite past friction between the lab and Washington. 

However, even as Anthropic calls for a global pause to rethink safety, the commercial machine keeps churning. The company just launched a massive Partner Hub to help consulting giants like Accenture and Deloitte train hundreds of thousands of workers on Claude. 

Anthropic also dropped the new ant CLI for the Claude Platform, a developer tool that makes every API endpoint runnable from the terminal. The CLI supports interactive OAuth logins and lets developers version-control Claude Managed Agents as YAML files in Git, giving Claude Code agents direct terminal-level execution skills. 

Meanwhile, a secret, unreleased version of their next Mythos model, codenamed Oceanus, was just leaked and sold via Chinese API proxies, forcing Anthropic to panic-pause its pre-launch safety testing.
