Google plans to release Gemini 4 before year-end

Google DeepMind head Koray Kavukcuoglu said the Gemini 4 model is in the early days of post-training and will launch "much earlier" than the end of this year, with observers speculating an October release. The launch is expected to ease concerns over the delayed Gemini 3.5 Pro.
