Trump signs voluntary federal review of frontier AI models
Rule ChangesThe US government has pulled Anthropic's newest models offline and staged OpenAI's GPT-5.6 launch — going further than Trump's voluntary framework in its first six weeks

Overview
Updated Jun 26Trump signed a voluntary framework on June 2 asking frontier labs to share their newest models with federal agencies for up to 30 days before release. Within ten days, the government had gone further. A June 12 export control directive forced Anthropic to kill worldwide access to Fable 5 and Mythos 5, its two newest models, after the government said it had found a jailbreak in the more capable one.
On June 26, OpenAI staged the launch of GPT-5.6 at government request, limiting early access to about 20 vetted companies while federal offices reviewed its cybersecurity capabilities. OpenAI said the arrangement should not become the default. For Anthropic's models, the government used an export control directive — no invitation required, no opt-out available.
Why it matters
The government has shown it can halt any frontier model launch — through the voluntary order, export controls, or both.

Drafted, postponed, narrowed and ultimately signed the frontier AI review order.
The NSA director decides which AI models qualify as 'covered frontier models' under a classified benchmark.
Renamed in June 2025 from the AI Safety Institute, CAISI is the federal body that evaluates AI capabilities and vulnerabilities.
Identified by the administration as a target frontier lab for the new voluntary review.
Identified by the administration as a target frontier lab; has long argued for federal access to powerful models.

US government forces Anthropic to pull Fable 5 and Mythos 5 worldwide
PolicyThe Commerce Department issued an export control directive requiring Anthropic to suspend all access to Fable 5 and Mythos 5 by any foreign national, citing a potential jailbreak. Because Anthropic could not segregate access, it suspended both models for all users worldwide. Anthropic disputed the rationale but complied. The models remained offline as of June 26.

Anthropic calls for globally coordinated AI slowdown
PolicyAnthropic published 'When AI builds itself,' arguing that AI is accelerating its own development faster than governance can follow and calling for a coordinated option to pause or slow frontier development. David Sacks accused Anthropic of regulatory capture, saying the proposal was designed to protect its proprietary models from open-source rivals. The report came three days after Anthropic confidentially filed for an IPO.

Historical Context
3 moments from history that rhyme with this story — and how they unfolded.
CFIUS review of TikTok (2019-2024)
The Committee on Foreign Investment in the United States ran a multi-year national security review of TikTok's US operations, ultimately producing a forced-divestiture bill that passed Congress in April 2024.
TikTok continued operating under negotiated security commitments while the review dragged on.
Voluntary cooperation eventually gave way to a statutory mandate when Congress decided the executive branch tools were not enough.
CFIUS shows how a voluntary or executive-only national security review of a tech product can run for years before Congress writes it into law. The same dynamic could play out with frontier AI.
Biden's frontier-AI reporting order (2023)
On October 30, 2023, President Biden signed Executive Order 14110, the first federal rule requiring top AI labs to share safety-test results and dual-use research with the government. It used the Defense Production Act to make reporting mandatory above set compute thresholds.
Major labs began submitting reports and signing voluntary cooperation agreements with the new AI Safety Institute.
Trump rescinded the order on his first day back in office in January 2025, ending mandatory reporting and leaving a 17-month gap before the June 2026 voluntary framework.
The 2023 order set the policy reference point the new one is measured against. Biden made disclosure mandatory; Trump has made it optional. The same labs, same models, same risks, two different legal regimes.
AI Safety Institute renamed to CAISI (2025)
Commerce Secretary Howard Lutnick renamed the AI Safety Institute as the Center for AI Standards and Innovation. The center's mandate was rewritten to focus on foreign AI threats, backdoors in adversary models and resistance to 'regulatory overreach.'
Safety-focused staff left or were reassigned. Industry kept its existing cooperation agreements but with a less independent counterpart.
By June 2026 CAISI was the technical body the new order had to lean on, but its independent evaluation capacity was thinner than it was under Biden.
The CAISI rebrand showed which way the administration was pulling on frontier-AI oversight before the new order existed. Safety advocates argue it weakens the body now charged with executing the voluntary review.
