What

In June 2026, Anthropic and OpenAI independently disclosed what they described as early signs of recursive self-improvement in deployed AI systems and called for international coordination to slow frontier development [1][3]. The US government responded with an export control directive on June 12 requiring Anthropic to block SK Telecom's access to Claude Mythos; lacking targeted access controls, Anthropic shut down Fable 5 and Mythos 5 globally [15]. By late June the US administration partially lifted those restrictions [21], Anthropic moved to restore access [22], and Commerce Secretary Howard Lutnick sent a letter to Anthropic's chief compute officer Tom Brown on June 26 [20] — consistent with Bloomberg's earlier report of a finalizing government deal [19]. A separate report that the Trump administration asked OpenAI to delay ChatGPT 5.6 [23] suggests government intervention in frontier model releases extends beyond the Anthropic-SKT dispute.

Why it matters

The partial resolution of the Anthropic standoff through direct government negotiation — rather than any technical fix — establishes a pattern: US national security concerns can pause global AI access, and bilateral deals can undo the pause. The reported ChatGPT 5.6 delay, if confirmed, shows this intervention model is not confined to a single lab or geopolitical incident.

Open questions

  • What are the specific terms of the US-Anthropic deal: does the partial lifting restore access for all customers or does it exclude SK Telecom and other Project Glasswing participants? [21][22]

  • What did Commerce Secretary Lutnick's June 26 letter to Anthropic's Tom Brown specify — was it the formal mechanism enabling the partial restoration? [20]

  • What prompted the Trump administration's request to delay OpenAI's ChatGPT 5.6 release, and is this part of a broader framework for government pre-approval of frontier model releases? [23]

  • Legal commentators have raised constitutional concerns about the government's authority to withhold AI models from public access [24][25] — has either Anthropic or the US government addressed these arguments formally?

Narrative

In June 2026, Anthropic and OpenAI independently published documents acknowledging that recursive self-improvement may already be underway in deployed AI systems. Anthropic's 'When AI Builds Itself' disclosed that Claude authored more than 80% of Anthropic's production code merged in May 2026, that per-engineer output reached 8x the 2024 baseline, and that Claude Mythos Preview accelerated model-training code approximately 52x [1][2]. OpenAI's concurrent policy blueprint called RSI 'potentially the most consequential frontier safety issue of the coming decade' and cited 'early signs of recursive self-improvement in today's systems' [3]. All three major labs publicly endorsed international coordination to slow frontier AI development [4].

Each lab's public safety stance sits alongside conduct that points the other way. Anthropic's global slowdown call was timed to a confidential S-1 filing at roughly $965 billion [5][6], and Anthropic engineers were reported embedded at the NSA for offensive cyber using Claude Mythos [7]. Sam Altman publicly endorsed coordinated slowdown mechanisms [8] while telling staff that a major RSI breakthrough would favor staying private [9]; OpenAI simultaneously filed confidentially for an IPO [10]. The US government directed CAISI — the federal oversight body OpenAI itself proposed — to stop publishing public AI model evaluations [11], removing the transparency mechanism OpenAI's own proposal depended on.

The most concrete government action came on June 12, 2026, when the White House told Anthropic to block SK Telecom's access to Claude Mythos over alleged Chinese ties at the Korean carrier [12][13]. Anthropic, unable to restrict access at the customer level, disabled both Fable 5 and Mythos 5 globally on June 13 [14][15]. SK Telecom, Samsung, and SK Hynix had all joined Project Glasswing — an Anthropic program for AI-assisted vulnerability detection — and used gated versions of Claude Mythos to protect core infrastructure [16][17]. South Korea's science ministry had separately secured government-level Mythos access before the shutdown [18], adding a diplomatic dimension to the commercial standoff.

By late June, the standoff moved toward resolution through direct government negotiation. Bloomberg reported on June 26 that Anthropic and the Trump administration were finalizing a deal [19]. That same day, Commerce Secretary Howard Lutnick sent a letter to Anthropic's chief compute officer Tom Brown [20], and the US administration subsequently partially lifted the restrictions on Anthropic's models [21]; Anthropic moved to restore access to Fable 5 and Mythos 5 [22]. Separately, a report emerged that the Trump administration had asked OpenAI to delay its ChatGPT 5.6 release [23], suggesting a broader practice of government review of frontier model releases beyond the SKT dispute. Legal observers raised constitutional questions about the authority to withhold AI models from public access [24][25], a challenge neither the government nor the labs have publicly addressed.

Perspectives

Anthropic / Dario Amodei

Believes current models may be approaching the RSI threshold; calls for a global coordinated slowdown; disclosed that testers of its most powerful unreleased model recommended against releasing it; Amodei says AI progress is in the sharp-acceleration phase of an exponential.

Evolution: Anthropic is moving to restore Fable 5 and Mythos 5 after the US partially lifted export control restrictions, having pursued a government deal rather than a technical fix; the lab still has not responded to Howard's consistency challenge.

[26][1][7][27][28][15][12][19][20][22][21]

OpenAI / Sam Altman

Acknowledges RSI as the top frontier safety issue; official blog endorses coordinated slowdown mechanisms; Altman targets AI-conducted research at OpenAI by March 2028; told staff a major RSI breakthrough might favor staying private.

Evolution: OpenAI reportedly delayed ChatGPT 5.6 at the Trump administration's request, a new concrete instance of government intervention in OpenAI's release schedule alongside the Anthropic case; IPO filing and the private-vs-public tension remain unresolved.

[3][29][8][11][9][30][10][23]

Google DeepMind

Supports an international organization to enable coordinated slowdowns; researchers published technical work identifying four pathways from AGI to ASI.

Evolution: Consistent with prior reporting.

[4][31]

Jack Clark (Import AI)

Declares 'alignment is not on track' and argues RSI without adequate alignment means 'rolling very scary dice'; treats the Fable/Mythos shutdown as confirming the risks of centralized AI control.

Evolution: Stance has sharpened from observational to declarative; the centralization-risk argument has gained traction through the suspension episode and its resolution via government deal rather than technical or policy fix.

[32][33]

Jeremy Howard

Argues the only internally consistent form of Anthropic's slowdown call would prohibit the lab with the top-ranked model from using it for frontier research; Anthropic fails this test.

Evolution: Argument stands uncontested.

[34]

Geoffrey Irving / Sequent

Founded Sequent on the argument that current lab alignment approaches are too empirical to provide principled safety confidence before ASI; plans $100-150M raise and 40-80 researchers.

Evolution: Funding targets and research scope confirmed; position unchanged.

[35][33]

Zvi Mowshowitz

Guardedly positive on OpenAI's blueprint but warns federal preemption of state safety laws is its most dangerous element; treats CAISI evaluation suppression as a significant transparency setback.

Evolution: Consistent; concerned governance mechanisms are losing enforcement teeth.

[36][4][11]

Critics and observers

Argue lab slowdown calls are competitive strategy timed to entrench incumbents; the Fable 5/Mythos 5 suspension drew growing attention as a demonstration that centralized AI can be shut off overnight; legal commentators have raised constitutional concerns about government authority to withhold AI models from the public.

Evolution: The legal/constitutional angle is new: observers are now arguing the government lacks authority to restrict public AI access, a challenge not formally addressed by either Anthropic or the US government.

[5][6][37][38][39][24][25]

Tensions

  • Howard argues Anthropic's continued use of its top-ranked model for frontier research negates its slowdown call; Anthropic has not responded. [34]
  • Altman publicly endorses coordinated slowdown mechanisms while telling staff a major RSI breakthrough would favor staying private; the two positions point in different directions on what OpenAI actually wants from RSI timing. [8][9][30]
  • OpenAI proposed CAISI as a federal body with public evaluation authority; the US government directed CAISI to stop publishing evaluations, removing the transparency mechanism OpenAI's own proposal depended on. [40][11]
  • The US simultaneously embeds Anthropic engineers at the NSA for offensive cyber and issued export controls forcing Anthropic's most capable models offline globally; the government's concern was geopolitical, not capability-based. [7][15][12]
  • Anthropic frames its slowdown call as a genuine safety response; critics argue it is regulatory strategy timed to a confidential S-1 at roughly $965 billion designed to entrench incumbents. [26][5][6]
  • Legal observers argue the government lacks constitutional authority to withhold AI models from public access; neither the US government nor Anthropic has formally addressed this claim. [24][25]
