Microsoft unveiled several new multimodal AI models for Azure AI Foundry at OpenAI DevDay in October 2025. The update includes GPT-image-1-mini, GPT-realtime-mini, and GPT-audio-mini, along with security improvements for GPT-5-chat-latest and the analytics model GPT-5-pro. The new models are designed to help developers build AI applications for text, image, audio, and video faster and at lower cost.
The Microsoft Agent Framework, an open-source SDK for coordinating multiple AI agents, is now available, as is OpenAI's new Agent SDK.
OpenAI is adding new controls to its Sora video app. According to Sora head Bill Peebles, users can now decide where AI-generated versions of themselves can appear - for example, blocking political content or banning certain words. Users can also set style guidelines for their digital likeness. These updates come in response to criticism over abusive deepfakes on the platform. Peebles also announced that Sora will soon officially support cameos featuring copyrighted characters. Recently, CEO Sam Altman said rights holders should have "more control" and will soon receive a share of Sora's revenue.
OpenAI's Sora 2 can handle knowledge questions, too. In a test by Epoch AI, Sora got ten random tasks from the GPQA Diamond Multiple Choice Benchmark covering natural sciences. Sora scored 55 percent, while GPT-5 managed 72 percent. To run the test, Epoch AI asked Sora to make a video of a professor holding up the answer letter on a sheet of paper.

Epoch AI points out that an upstream language model could tweak the prompt before the video is created and slot in the answer along the way. Other systems, like HunyuanVideo, use similar re-prompting tricks, but it's not confirmed whether Sora does the same. Either way, the lines between text and video models are starting to blur.
OpenAI has acquired the AI finance startup Roi, known for offering investment advice based on individual financial data. The service will shut down on October 15. Roi's CEO and founder Sujith Vishwajith is the only team member joining OpenAI. The deal supports OpenAI's interest in personalized consumer AI. The purchase price was not disclosed.

ChatGPT still dominates the AI market, but Google Gemini is catching up. Over the past year, Similarweb says Gemini's share of generative AI traffic jumped from 6.5 percent to 13.7 percent. ChatGPT leads at 73.8 percent, down from 87.1 percent a year ago.

The rest of the market is much smaller. DeepSeek holds 3.9 percent, while Perplexity and Grok each have 2.0 percent. Claude sits at 1.8 percent, and Microsoft's Copilot brings up the rear with 1.2 percent. These numbers haven't shifted much for the smaller players. Overall traffic to AI services continues to grow.
