DeepMind says Gemini 4 has entered post-training and will ship "much earlier" than end of 2026

★★★after cutoffmilestoneGoogle DeepMindconfidence: medium

At The Information's AI Agenda Live summit (reported 24–25 Sept 2026), new DeepMind head Koray Kavukcuoglu said Gemini 4 is in early post-training and that Google intends to release an early post-training version "as soon as possible", well before year-end, followed by iterative updates. Google had not shipped a new flagship since Gemini 3.1 Pro (Feb 2026).

Key facts

What happened

Speaking publicly for the first time since taking over DeepMind, Kavukcuoglu said Gemini 4 had entered post-training and would be released early and improved iteratively.

Why it matters

Signals Google's response to GPT-6 and Anthropic's latest models after months of Flash-only releases. Exact event date is inferred (the summit was "Wednesday" before Dataconomy's 25 Sept report = 23 Sept); release date for Gemini 4 not yet known.
