Openly unveiled new API updates on his Dev Day on Monday, the GPT -5 Pro, its latest language model, its new video generation model Sora 2 and a small, cheap voice model.
The updates were part of a series of declarations to drive to developers to the opener’s ecosystem with the introduction of an agent-building equipment and the ability to create applications in ChatzPT.
The GPT -5 Pro addition can apply to the developers for the applicable applications in finance, legal and healthcare -“OpenAEE CEO Sam Altman” requires “high accuracy and depth of logic”.
Ultman also points out that in the future voice capabilities will be essential because it quickly becomes one of the primary ways that people use to contact AI. To that end, the OpenA API is launching a small, cheap voice model “GPT-Realtime Mini” that supports short-latacy streaming interactions for audio and speech. The new model is 70% cheaper than Openai Model in the previous advanced voice However “the same voice promises to express the quality and feelings of the same voice.”
To the end, the creators involved in the OpenAI developed ecosystem can now tap the API to Sora 2. OpenAIA’s latest audio and video generator Sora 2 has released, along with the Sora app last week, a ticket contestant filled with short AI-exposed videos. Sora app allows users to make videos on the basis of their own, friends or prompts and share it through the algorithmical feed of the tiktok-style.
“[Developers] Now the same model has access to Sora 2’s stunning video outputs directly strengthen your own app, “said Ultman.
The previous generation of Sora 2 is made with more realistic, physically consistent scenes with synchronized sound and greater creative control – up to the stylized visual from the camera’s direction.

“For example, you can take the iPhone view and prompt it to Sora to extend it to a broom, cinematic wide shot,” said Ultman. “But one of the most interesting things we are working is that this new model is not just speech with Visuals, not just speech, rich soundscapes, enclosed audio, synchronized effects that you are based on” based on what you see ”
Sora 2 is created as a concept development tool, it is a visual initial point for an advertisement based on a product’s general view, or a matte designer turns into a sketch toy concept-an example given on Dove Day, which brings toys generator AI in the pipeline with Barbie-maker.
