Gemini 4

Google unveiled Gemini 4 Argon, its new flagship model, which sits behind only Claude Opus 5.5 and Claude Sonnet 5.5 on the Artificial Analysis Intelligence Index. Access begins with trusted cybersecurity partners, with no date given for wider availability.

Google DeepMind's new head Koray Kavukcuoglu says Gemini 4 is in early post-training and could ship well before year-end, following the quiet cancellation of Gemini 3.5 Pro. He downplayed the AGI question that defined predecessor Demis Hassabis's tenure, calling it 'not the right conversation.'

Google has confirmed it is training Gemini 4 in what it calls its 'most ambitious pre-training run yet,' with CEO Sundar Pichai saying the next-generation model will need a 'much larger base model' to compete at the frontier. No specs, benchmarks, or firm release date have been disclosed, though historical cadence points to a November or December 2026 launch.
