– The new “gpt-realtime mini” voice model is 70% cheaper than previous versions while maintaining voice quality and supporting low-latency streaming.
– Sora 2, now available in preview via API, offers more realistic scenes, synchronized sound, and enhanced creative control for video generation.
– Sora 2 enables developers to integrate advanced video capabilities into their apps and is positioned as a tool for concept development in industries like advertising and toy design.
OpenAI has introduced a suite of powerful new AI models and developer tools, marking a significant expansion of its platform aimed at empowering creators and businesses. During its recent Dev Day event, the company announced GPT-5 Pro, the advanced Sora 2 video generation model, and a more affordable voice model called gpt-realtime mini. These releases are designed to attract developers to build within OpenAI’s ecosystem, offering enhanced capabilities for a wide range of applications.
The new GPT-5 Pro model is positioned to serve sectors demanding exceptional accuracy and sophisticated reasoning, such as finance, legal services, and healthcare. According to OpenAI CEO Sam Altman, this model addresses the need for high accuracy and depth of reasoning in professional environments. Alongside this, the company emphasized the growing role of voice interaction in AI. The gpt-realtime mini voice model supports low-latency streaming for audio and speech, delivering the same expressive quality as previous versions but at a substantially lower cost, reportedly 70 percent cheaper than earlier advanced voice offerings.
Creators working within the OpenAI developer ecosystem can now access Sora 2 through a preview in the API. This latest iteration of OpenAI’s video generation tool builds on its predecessor by producing more realistic and physically consistent scenes, complete with synchronized audio. Sora 2 also provides users with greater creative control, enabling detailed camera direction and stylized visual outputs. Altman highlighted that developers can integrate the same technology that powers Sora 2’s impressive video results directly into their own applications.
One standout feature of Sora 2 is its ability to synchronize sound with visuals, creating rich soundscapes and ambient audio that match what appears on screen. For example, a user can start with an iPhone view and prompt the model to expand it into a cinematic wide shot. Altman shared a use case from Mattel, where designers transform sketches into toy concepts, illustrating how generative AI is being incorporated into creative and manufacturing workflows. This collaboration with the Barbie-maker underscores OpenAI’s push to embed its technology across diverse industries.

By lowering costs and raising the bar for quality and interactivity, the company aims to foster innovation across sectors from entertainment to enterprise.
