Today is June 30, 2026 — the last day of Q2. It closes with a mixed scorecard for the four frontier models builders spent the past six weeks waiting on: one suspended by government order, one missing its second consecutive quarterly deadline, one confirmed for “July” without a date, and one technically launched but accessible to roughly twenty organizations in the United States.

This is a status report and planning guide as Q3 opens.

The Scorecard as Q2 Ends

Model Provider Q2 Target Q2 Outcome Next Gate
Fable 5 Anthropic Available (launched June 9) Suspended June 12; Day 18 July 8 (ID verification)
Grok 5 xAI Q2 2026 Missed — Q3 now target Unknown
Gemini 3.5 Pro Google June 2026 Missed — “July” confirmed Mid-to-late July
GPT-5.6 Sol/Terra/Luna OpenAI Late June Launched June 26; ~20 gov orgs only End of July (GA)

None of the four are in general API access today.

Fable 5 (Anthropic) — Day 18, July 8 Is the Next Gate

Fable 5 is the most consequential and most covered delay on this list. It was in market for three days (June 9–12), then suspended under a US Department of Commerce export control directive citing concerns about bypass methods enabling vulnerability identification. That was eighteen days ago.

What changed since the June 19 update:

On June 28, the US government notified Anthropic that Mythos 5 — the cybersecurity-oriented model in the same class — can be redeployed to approximately 100 pre-approved critical infrastructure organizations in the US. That partial restoration signals that the review framework is working through the model family, not stonewalling it.

For Fable 5 (the general-access version), the Pentagon and NSA still have not signed off. Prediction markets priced 57% odds of restoration by July 1 — those markets resolve NO today. The next structural anchor is July 8, when Anthropic’s updated privacy policy takes effect, introducing government-issued ID verification and biometric data (via third-party vendor Persona). Analysts see this as a potential US-citizens-only restoration path — a technical mechanism that could satisfy export control requirements by verifying that users are US persons.

The August 1 deadline matters too: that is the 60-day mark on Trump’s June 2 executive order directing AI companies to provide early government access to frontier models. The export control action against Fable 5 was downstream of that order. If the Pentagon-NSA review completes inside the 60-day window, August 1 becomes a hard backstop.

Builder action:

  • For builders currently planning on Fable 5: Claude Opus 4.8 and Haiku 4.5 are available in the API today via Claude.ai, Amazon Bedrock, and Google Vertex AI. If your use case is agentic coding, Claude Code with Sonnet 4.6 is in full production use.
  • Watch July 8 specifically: if Anthropic rolls out Persona verification targeting US users, a restoration announcement could follow within days.
  • Do not block product decisions on a July date without a named date. The July 8 path is plausible but not confirmed.

Grok 5 (xAI) — Second Consecutive Quarterly Miss

Grok 5 has now missed two consecutive quarterly deadlines. xAI targeted Q1 2026 in its January Series E announcement, then extended to Q2. Q2 ends today. No official Grok 5 announcement, no release date, and no API documentation exists for the model.

What this model is supposed to be: A 6-trillion-parameter flagship trained to match or exceed frontier labs on reasoning, coding, and scientific tasks. xAI has framed it as their AGI-track model. The training compute required is substantial; xAI’s Colossus 2 cluster is reportedly still running training runs.

What’s available now: xAI has been actively releasing mid-tier models this quarter rather than the flagship:

  • Grok 4.3: Available in API. 1M token context, native video input, native PDF/PPTX/XLSX file generation. The current best xAI model for production use.
  • Grok Build 0.1: Public beta via API. Smaller, purpose-built for coding agents. Available now.
  • Grok 4.5: Private beta. Accessed via SpaceX and Tesla internal deployments. No general API access.

Builder action: Q3 2026 (July–September) is the realistic window for Grok 5 API access, but xAI has given no specific date. Do not hold architecture decisions for Grok 5. Evaluate Grok 4.3 as the current xAI ceiling for production use. If Grok 5 ships in Q3, the lead time between announcement and stable API access has historically been 3–10 days for xAI models.

Gemini 3.5 Pro (Google) — June Window Closed, July Confirmed

Gemini 3.5 Pro’s missed June window is the most predictable miss on this list. Sundar Pichai said at Google I/O (May 19): “give us until next month to get it to you.” That was a June commitment. Business Insider reported on June 27 that the target has slipped to July — Google declined to comment officially.

What happened: Token efficiency issues surfaced during Flash early testing. Gemini 3.5 Pro prioritizes long-context coding tasks and “Deep Think” reasoning at scale; those require more refinement time than Flash’s consumer-optimized profile. The departure of Noam Shazeer, John Jumper, and two additional Gemini researchers in the same week the delay was reported added noise to the signal, though the departure timeline appears to predate the efficiency issues.

What’s available now: Gemini 3.5 Flash is in full GA — the default model in the Gemini app and AI Mode in Search. API pricing is $1.50/$9.00 per million input/output tokens.

Builder action: For mid-tier, high-speed tasks, Flash is strong and fully available. For use cases requiring the 2M context window or Deep Think ($250/month Ultra gate), plan for mid-to-late July. The Vertex AI enterprise preview remains the only current access path for Pro.

GPT-5.6 Sol/Terra/Luna (OpenAI) — Launched, But Not For You

GPT-5.6 is technically not a miss — OpenAI launched it on June 26, on schedule with the June 22–28 prediction market window. The issue is access. All three tiers (Sol, Terra, Luna) are currently restricted to approximately 20 government-vetted organizations under Trump’s June 2 executive order, which requires that covered frontier models go through national security review before broader release.

What launched:

  • Sol: Flagship tier. Terminal-Bench 2.1 score of 91.9% in ultra mode (new SOTA). Multi-subagent ultra reasoning.
  • Terra: Balanced everyday model. The likely default once GA.
  • Luna: Fast, high-volume tier. The cost-optimized option.

Pricing: $5/$30 per million input/output tokens — same as GPT-5.5’s rate card.

What’s available now: GPT-5.5 and GPT-5.5 Pro are in full API access (GA since April 24). For most production workloads, GPT-5.5 Pro covers the use case gap until GPT-5.6 Terra or Luna achieve GA.

Builder action: The end-of-July GA estimate for GPT-5.6 is market consensus, not an OpenAI commitment. If your roadmap needs GPT-5.6 Sol’s reasoning capability specifically, plan for Q3 2026 as your evaluation window. For everything else, GPT-5.5 Pro is the reasonable production bet.

What’s Actually Available Right Now

For builders who need to make stack decisions without waiting for any of the above:

Use Case Available Today
Frontier reasoning / coding Claude Sonnet 4.6 · GPT-5.5 Pro
High-volume, low-latency Gemini 3.5 Flash · Claude Haiku 4.5
Agentic coding Claude Code (Sonnet 4.6) · GPT-5.3 Codex
Computer use Claude Opus 4.8 · GPT-5.5 (computer use tool)
xAI / Grok Grok 4.3 (API) · Grok Build 0.1 (API beta)

Q3 2026 is when the frontier access picture resolves. Until then, the above table is what you build on.

What July Is Actually About

The four-model delay story has concentrated attention on what’s missing. But the past month has also surfaced what is arriving in July:

  • July 6: OpenAI Workspace Agents GA — agents that can operate in your Google Workspace and Microsoft 365 environment. This ships next week.
  • July 8: Anthropic Persona ID verification takes effect — the potential Fable 5 trigger.
  • July 10: SK Hynix Nasdaq ADR debut — $29B listing. HBM4 supply confirmation for Vera Rubin / Nvidia’s next-gen AI platform. GPU cloud pricing implications by Q4.
  • Mid-to-late July: Gemini 3.5 Pro GA target.
  • End of July: GPT-5.6 general access target.
  • August 1: 60-day government review deadline under Trump’s executive order.

July is not a waiting month — it’s the delivery month. Builders who have been evaluating against current models are well-positioned to move fast when access opens.
