OpenAI is making a major shift for its flagship AI product. ChatGPT will soon begin displaying advertisements alongside its answers for users in the United States. This move introduces a significant new revenue stream for the company. The ads, based on the context of a user’s conversation, will appear in tinted boxes either above or below the AI’s response. OpenAI confirmed that ads will not appear for sensitive topics like health or politics. The decision marks a change from CEO Sam Altman’s previous reluctance to use an ad-based model. The company is also launching a low-cost subscription tier called ChatGPT Go.

Alphabet just made history. The technology giant surpassed a $4 trillion market capitalization for the first time, cementing its position as the world’s second-most valuable company. The surge follows a period of investor doubt, now erased by powerful AI momentum. A key driver is a landmark deal with Apple, which will use Google’s Gemini AI as the foundation for its next generation of Siri. This partnership gives Alphabet an unmatched distribution advantage. Beyond AI, Alphabet’s Wing drone delivery service announced a major expansion with Walmart, planning to scale operations to an additional 150 stores. The valuation reflects strong confidence in Alphabet’s ability to monetize new technologies.

Google has launched a major update for its Gemini AI. A new beta feature, ‘Personal Intelligence,’ connects the chatbot to a user’s private data across Google’s services, including Gmail, Photos, and Search history. Now, users can ask Gemini to find specific vacation details buried in old emails or retrieve information from past online activity. The upgrade aims to make the AI a more capable personal assistant, giving it a distinct advantage over competitors by using Google’s extensive ecosystem of user information. This opt-in functionality is currently rolling out to select AI plan subscribers in the United States before a wider release.

Nvidia and Microsoft have thrown their weight behind a new AI drive to advance gene therapies. The effort applies large models to genetic design and analysis, with the goal of speeding discovery and cutting costly missteps. Tech teams plan to supply compute and tools, while biotech partners contribute data and lab validation. Supporters say this could sharpen target selection and improve predictions before trials. Skeptics warn about data bias, safety, and oversight. The move adds fuel to a race among cloud and chip providers to win global biopharma workloads as demand for training and inference surges. Researchers and drugmakers see tighter ties with Big Tech as development cycles compress.

Apple has struck a multi-year deal to use Google’s Gemini AI and cloud tech to build a more personalized Siri arriving this year. The companies say Gemini will support Apple Foundation Models and future Apple Intelligence features while core processing stays on devices and Private Cloud Compute. Apple has spent a year rebuilding Siri to take actions and understand personal context, but Apple delayed the rollout last March. It also tested a custom Gemini for “World Knowledge Answers” that searches the web and produces AI summaries. Google launched Gemini 3 in November, and it tops key benchmarks. Apple reshuffled leadership, with Vision Pro chief Mike Rockwell replacing John Giannandrea after his departure. Apple continues talks with OpenAI, Anthropic, and Perplexity for integrations.
