Sakana AI and 360 Launch Fugu and Tulongfeng Models

FIRST LOOK ATLAS OWASP HIGH Significant risk · Prioritise patching ▲ 6.8 Cohere AI (via HN)

Sakana AI's Fugu and Chinese firm 360's Tulongfeng are frontier AI models positioned as functional alternatives to Anthropic's export-restricted Mythos and Fable 5, with Fugu explicitly designed for agentic orchestration across third-party model APIs. For defenders, the proliferation of cybersecurity-focused frontier models outside US regulatory reach removes a key friction point that previously slowed adversary access to high-capability AI offensive tooling. The agentic, multi-model orchestration design of Fugu in particular introduces compounded supply-chain and prompt-injection risk for any enterprise connecting these models to existing tool ecosystems.

Anthropic's Mythos 5 and Fable 5 Hit by Export Block

Anthropic's Mythos 5 and Fable 5 Hit by Export Block

FIRST LOOK ATLAS OWASP HIGH Significant risk · Prioritise patching ▲ 7.2 TechCrunch AI

The Trump administration's June 2026 export block on Anthropic's Mythos 5 and Fable 5 models has forced a long-overdue reckoning with AI vendor dependency as a first-class operational risk, giving security and procurement teams the concrete, real-world evidence needed to justify resilience investments that were previously treated as theoretical. This event closes a critical gap in organisational risk registers by demonstrating that AI model access continuity must be governed with the same rigour applied to any mission-critical third-party dependency — complete with contingency planning, contractual protections, and evaluated alternatives. What remains unaddressed is the absence of industry-wide standards for AI vendor continuity obligations, leaving individual organisations to negotiate protections without consistent benchmarks.
