This approach enabled us to talk to frontier AI models for the first time, but the complexity came at a cost: information could be lost across models, and responses were slow and stilted.OpenAI
In addition, because turn detection is based on silence, even a brief pause or background noise could be mistaken for the end of turn — causing the model to interrupt at unnatural times.OpenAI
Built-in safeguards Because voice conversations unfold in real time, we also built safeguards that can act while the model is speaking.OpenAI
It also has the ability to spin off harder tasks to GPT-5.5: For questions that require web search, deeper reasoning, or more complex work, it delegates to our latest frontier model behind the scenes and brings the result back into the conversation when it’s ready.Simon Willison
The previous voice mode in the ChatGPT app was based on a GPT-4o era model, with a knowledge cut-off some time in 2024.Simon Willison
My longest conversation with the new model has been a full hour while walking the dog (and taking photos of pelicans ).Simon Willison
