At the Dev Day conference, OpenAI presented updates to its API, including the presentation of GPT-5 Pro (the latest language model), the Sora 2 video creation model, and a more compact and economical voice model.
These updates are part of a series of announcements aimed at bringing developers into the OpenAI ecosystem, including the launch of the AgentKit agent creation tool and the ability to develop applications directly in ChatGPT .
As OpenAI CEO Sam Altman explained, the introduction of GPT-5 Pro should attract the attention of developers working on programs for the financial, legal, and medical sectors — that is, those industries where “high accuracy and depth of reasoning” are required, writes TechCrunch.
Altman also noted that voice capabilities will be key in the future, as voice communication is quickly becoming one of the main ways people interact with AI. To do this, OpenAI is introducing gpt-realtime mini , a more compact and cost-effective voice model in the API that provides fast streaming of audio and speech. The new model is 70% cheaper than OpenAI’s previous advanced voice model, but promises “the same quality and expressiveness of voice.”
Finally, content creators working in the OpenAI developer ecosystem can now get early access to Sora 2 in the API . OpenAI released Sora 2 — its latest model for audio and video generation — last week alongside the Sora app.
“Developers now have access to the same model that creates amazing videos in Sora 2 and can use it directly in their applications,” said Altman.
Sora 2 is an improved version of the previous model, offering more realistic, logical scenes with synchronized audio and expanded control capabilities - from controlling the camera angle to choosing a picture style.
“For example, you can take a frame shot on an iPhone and have Sora prompt it to expand it into a large-scale cinematic frame,” Altman explained. “But one of the most exciting things we’ve seen is how well the new model combines sound and image. It’s not just speech, but also rich soundscapes, atmospheric noises, and synchronized effects that match exactly what’s happening on screen.”
