  • Anthropic's Mythos 5 returns to select U.S. critical-infrastructure and defense organizations under government authorization
  • SoftBank's Masayoshi Son signals interest in a TEPCO stake — an infrastructure play to attract domestic data centers
  • As export limits drag on, Mythos-like models spread across Asia — China's 360 joins in

The center of the day was the partial return of Anthropic's Mythos 5, which had been suspended since June 12 under a U.S. export-control directive. The authorized scope is narrow — select U.S. organizations in critical infrastructure and defense — while a broader reopening and any expansion of access remain in the hands of ongoing talks with the government.

In Japan, the question shifted to where the computation will be powered. SoftBank's Masayoshi Son signaled interest in taking a stake in Tokyo Electric Power (TEPCO) with an eye on attracting data centers to the country. In Asia, meanwhile, newcomers moved into the supply gap that the restrictions had opened. The rule of who may use a model, the power and infrastructure that sustain it, and the competition that fills the vacuum — the state's involvement in AI models moved on a layer separate from raw capability today.

Anthropic's Mythos 5 Returns to Select Organizations Under Government Authorization

Anthropic's Mythos 5 model has begun returning to select U.S. organizations in critical infrastructure and defense, under authorization from the U.S. government (follow-up).

Here is the background. On June 12, the U.S. government issued an export-control directive citing national security and asked Anthropic to halt access to Mythos 5 for foreign nationals. Because the company cannot screen users by nationality in real time, it disabled the model for all customers to ensure compliance. That blanket suspension is now lifting, but only in part.

The authorization came on June 26. Anthropic says it is first restoring access for a limited set of critical-infrastructure and defense organizations, and that it will keep working with the government on expanding the scope of Mythos 5 access. A full reopening for the general public — including the top-tier Fable 5 model — has no announced timeline.

For those responsible for adoption, this is more than a recovery notice. A model that was halted for reasons unrelated to its technical merits is now coming back in stages, paced by the progress of talks with the government. The order of who gets to use it first, and for what, remains shaped by policy decisions.

SoftBank's Son Signals Interest in a TEPCO Stake to Anchor Domestic Data Centers

SoftBank Group's Masayoshi Son has signaled interest in taking a stake in Tokyo Electric Power (TEPCO), Japan's largest electric utility.

The aim is to secure the infrastructure needed to attract data centers to Japan. Because large AI facilities consume enormous amounts of electricity, the idea is to gain visibility over power supply through involvement with a utility, and to pursue that hand in hand with site recruitment.

The move adds a new dimension to industrial policy in the AI era. Discussion in Japan has tended to gather around model performance and use cases; what Son raised is the question one step earlier — how to keep the power and the computing base inside the country. Alongside the rule of who may use a model, the question of who sustains its foundation has surfaced in the same week.

As Export Limits Drag On, Mythos-Like Models Spread Across Asia

With export restrictions on Anthropic's models persisting, models that claim to rival Mythos keep emerging from Asian startups (follow-up).

According to TechCrunch, the latest entrant is China's 360, which unveiled "Tulongfeng," a cybersecurity tool for discovering software vulnerabilities that it says matches Mythos in capability. It follows "Fugu," the agent-orchestration model released earlier by Tokyo-based Sakana AI — a sign that the move to fill the supply gap opened by the restrictions is shifting from a single company's bet to a regional pattern.

These launches coincided with the moment U.S. models became unavailable. Sakana AI co-founder Ren Ito framed the shift as temporary, saying U.S. models remain important to Asia. The longer the restrictions last, however, the more alternatives keep stacking up as real, shipping products across the region.
