A Tokyo startup and a Beijing security firm just launched AI tools to fill the gap Anthropic’s export ban created
THE SO WHAT
The vacuum from Anthropic’s export restrictions is being filled quickly—Sakana AI’s Fugu and 360 Security’s Mythos-like models show that capability gaps in one jurisdiction become market openings in another. If you operate across regions, you’ll need a multi-vendor, multi-regime model strategy rather than betting on a single US lab.

Applied AI'We don’t believe this kind of government access process should become the long-term default': OpenAI unveils big GPT-5.6 upgrades for ChatGPT, but you can't use them yet
Model access is now a negotiation between labs and governments—GPT-5.6 exists, but US testing holds back general release. If your roadmap assumes day-one access to frontier capabilities, build contingency plans around staggered, jurisdiction-specific rollouts and potential pre-clearance regimes.
Applied AIClaude Mythos 5 is back, but only for a select group of US institutions
Model access is now being gated like dual‑use infrastructure—Mythos 5 comes back first for US institutions tied to national security and critical infrastructure. If your workflows depend on frontier models, treat regulatory risk like a supply-chain dependency, not an edge case.
Applied AISource: the Trump administration is close to allowing Anthropic to restore access to Fable 5; limits could be lifted as soon as this coming week
A 15‑day outage for a flagship model on policy grounds is a live-fire test of concentration risk in AI stacks. If Fable 5 comes back next week, the lesson isn’t relief—it’s to build multi‑model routing and clear fallbacks before the next regulatory shock.
Anthropic's Mythos 5 gets a limited carveout from US restrictions
Carving out Mythos 5 access for US critical infrastructure operators creates a two-tier model regime—high-end capabilities for defense and utilities, constrained access for everyone else. If you build for regulated sectors, assume your customers may get privileged model access you don’t, and design your integration and procurement story around that asymmetry.
