Google has reached a milestone where artificial intelligence now writes 50% of its code, reflecting a substantial integration of AI-assisted programming within the company. This metric is based on the proportion of accepted characters generated by AI-based code completion compared to manual coding input. Concurrently, Google is preparing to release an advanced version of its AI system, Gemini Deep Think, which is expected to launch in the coming weeks. This new iteration reportedly features an innovative Agent Mode and demonstrates performance close to the leaked 'Kingfall' model. The developments underscore Google's ongoing investment in AI technology to enhance software development and AI capabilities.
