Model releases

• [2026-06-16] Anthropic — the dispute over the Fable 5 / Mythos 5 shutdown turned into duelling public narratives. White House AI adviser David Sacks, in an account laid out on X and reported widely, said the administration warned Anthropic that Fable 5 had been jailbroken — and that the trigger was learning Mythos had been made available to a foreign entity with “direct ties to the Chinese Communist Party.” By Sacks’s telling, the government asked Anthropic to patch the jailbreak or pull the model, CEO Dario Amodei refused (calling the bypass not serious), and the administration issued the export control “reluctantly”; it wants the restriction lifted once the jailbreak is patched, so “the ball is in Anthropic’s court.” Anthropic disputes the framing: a spokesperson said the White House never raised Chinese access in its conversations with the company, that Anthropic already prohibits access to its products from within China, and that the bypass is narrow and reproducible on rival models. Both models remain dark. The shift matters because it reframes a “misunderstanding” as a standoff with a stated unlock condition — patch the jailbreak — which changes what restoration actually requires.

  Read against Anthropic’s flat denial, that “unlock condition” is shakier than it sounds — there is no agreed fix to ship when the two sides don’t even agree a fix is needed — so for anyone hoping to plan a return to Fable 5, “patch the jailbreak” is less a checklist item than a negotiation, and a weaker basis for a timeline than the earlier “as soon as possible.”

• [2026-06-16] Anthropic — with the models still suspended, the market started pricing the outcome: Kalshi traders put ~58% odds on access being restored before July 1 and ~74% by July 10, betting the standoff resolves in weeks rather than dragging on. Separately, the episode is now being read as a structural risk to Anthropic’s business — coverage framed the shutdown as a fresh problem for its IPO pitch, since a regulator demonstrably can switch off its flagship product overnight. The two threads sit in tension: a near-term restoration is the consensus bet, but a government that has shown it will pull a deployed model is a standing risk no quick fix erases. (source, source)

  For anyone weighing whether to wait out the suspension or move off it, these odds are the only quantified signal on offer — but ~58% on “back by July 1” is barely better than a coin flip, so treating it as “just wait a couple weeks” is a heavier bet than the number actually supports.

Watch list

• Fable 5 / Mythos 5 restoration — both still suspended under the June 12 export-control directive, now with a stated unlock condition (Sacks: lifted “once the jailbreak is patched”). Watch for whether Anthropic ships a patch it has publicly called impossible-without-degrading-defense, and whether access returns with nationality-based gating attached. (official)

  The informative part will be which side moves: a shipped patch means Anthropic gave ground it called impossible without degrading defense, while access returning untouched means the government did — so the shape of the resolution, not just its date, reveals who held the leverage.

• Fable 5 plan window closes June 22 — included on Pro/Max/Team/Enterprise through June 22, usage-credit-metered from June 23; moot while the model is dark, but it returns the instant access does, and the clock currently expires mid-suspension. (official)

  The live risk is less the date than the meter — if access returns after June 22, the model comes back already usage-billed, with the included days lost to the blackout, so the thing to watch is whether Anthropic resets that clock rather than restoring a model that bills from minute one.

• xAI Grok V9-Medium (mid-June) — the ~1.5-trillion-parameter, Cursor-trained coding model finished training May 25 and is still expected this month; mid-June has nearly passed with no model card, API string, or release. (prior coverage)

• Gemini 3.5 Pro (late June) — reportedly in limited Vertex AI enterprise preview with GA targeted late June; still no model card, public benchmarks, or pricing for the promised 2M-token context and Deep Think mode. (prior coverage)

  Unlike the others stuck on this list, Gemini has a named path to market in Vertex AI, so its GA is something a team with a Google Cloud account can watch for directly — the preview flipping to general availability — rather than waiting on a model card or launch post.
