Google starts post-training on next-generation Gemini 4

Alphabet is nearing the launch of its next-generation Gemini 4 artificial intelligence model. The company has moved the system into the final stages of development as competition heats up across the technology sector.

Koray Kavukcuoglu, head of Google DeepMind, stated on Wednesday that the team is now in the early stages of post-training for Gemini 4. This process involves fine-tuning the base model to improve performance and reliability before a broader public rollout.

The update comes as Google battles OpenAI, Anthropic and Meta for market share in frontier AI models. Gemini remains a core pillar of Alphabet's broader AI strategy across search, cloud services and consumer products.

The announcement did not disclose specific capabilities, pricing or an official release date for Gemini 4. Investors and industry watchers await the formal debut to assess how the new model performs against rival platforms.
