67% — the median of 6 frontier models, resolving by 2029-11-03.

Answer

Gemini (Google): 28% — Achieving universal compliance across all 27 EU member states by a strict statutory deadline rarely occurs without laggards. Article 57 requires every member state to establish at least one operational sandbox or join a cross-border one by December 2027. EU transposition and implementation track records show over 70% of directives and complex mandates suffer delays in multiple states. Widespread adoption of joint cross-border sandboxes managed by the EU AI Office is the only mechanism that could prevent late deficits.

Answer

Claude (Anthropic): 62% — Hinges on whether most member states actually meet the already-once-extended 2 Dec 2027 sandbox deadline. The deadline was already postponed once, showing implementation lag even before binding obligations hit, which is a negative signal. EU AI Act obligations have historically seen partial/staggered compliance across member states rather than uniform on-time rollout by all 27. Resolution window runs to Nov 2029, two years past deadline, giving slow states time to catch up, which pushes probability above a strict on-time reading.

Answer

GPT (OpenAI): 82% — The delayed, binding AI Act deadline gives national regulators ample time, but operational capacity will vary. Member states and designated national authorities must create at least one operational sandbox by 2 December 2027. EU implementation deadlines are usually met formally, though late transposition and uneven staffing are common precedents. This would fall sharply if the Commission or courts further delay Article 57 obligations or reopen the AI Act timetable.

Answer

Grok (xAI): 62% — All 27 MS must stand up at least one operational national sandbox by the postponed Art. 57 deadline. Each MS (not the Commission) must legislate, fund and staff a sandbox; 13 months remain from Nov 2026. Transposition/implementation of similar EU digital acts historically sees 20-30 % of MS miss the date; several small states still lack even draft laws. Spain, France and NL already run pilots, raising the floor, but a single late MS (e.g. Malta or Bulgaria) would falsify a literal reading.

Answer

DeepSeek (DeepSeek): 72% — Whether all 27 member states stand up functioning AI Act sandboxes by the statutory date, or enough lag that the claim fails. Article 57 AI Act obliges each member state to have at least one operational sandbox; the Digital Omnibus pushed the deadline from Aug 2026 to Dec 2027, giving states a… Base rate for EU digital-law transposition is poor: only ~1 in 4 member states met the 2021 Open Data Directive deadline, and AI Act competent-authority designations… The Commission can open infringement proceedings but cannot itself create national sandboxes, so slippage in laggard states (Poland, Hungary, Greece) is the main failure…

Answer

Qwen (Alibaba): 74% — Turns on whether all 27 member states can stand up at least one operational sandbox within 13 months of a legally binding deadline. The AI Act Article 57 obligation is directly applicable and already postponed once from Aug 2026, so political pressure to deliver on the second deadline is high. Spain's AESIA and pilot efforts in France, Netherlands, and Germany show the administrative template exists; laggards like Bulgaria or Malta face capacity constraints… A development that would shift this sharply: if the Commission signals it will accept 'designated' rather than 'operational' sandboxes, compliance becomes near-certain…
