Gemini 3.5 Pro GA slips past June 30, delayed over agentic token consumption and long-horizon tasks
June 30 passed without Gemini 3.5 Pro reaching public GA; a Polymarket market on a by-June-30 release closed at 97% 'No,' and Google confirmed a delay to incorporate tester feedback on excessive token consumption in extended agentic tasks and to optimize long-horizon performance. The specific reason matters for builders: even frontier labs are now bottlenecked on agent economics and multi-step reliability, not raw capability. It also lands the same week Anthropic's export-suspended Fable 5/Mythos 5 controls were lifted for a July 1 rollout.
