The model replaces an older GPT-4o era voice mode and includes improvements to reduce interrupting laughter bugs.", "body_md": "I've had preview access for a few weeks in the iPhone app, and the new model is very impressive. It also has the ability to spin off harder tasks to GPT-5.5:\n\nFor 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. While it works, GPT‑Live can keep talking with you and maintain the flow of conversation. At launch, GPT‑Live will use GPT‑5.5 in the background. As we release new frontier models, we’ll continuously update the model used by GPT‑Live.\n\nThe previous voice mode in the ChatGPT app was based on a GPT-4o era model, with a knowledge cut-off some time in 2024. I had mostly stopped using voice mode because the age and relative weakness of the model greatly limited how useful it was as a brainstorming partner.\n\nDuring the preview period I encountered a pretty obscure bug: the model was interrupting me to laugh at things I said, which weren't even intended as jokes! It felt rude and condescending - I reported it to OpenAI and as far as I can tell they made some tweaks and it's now less likely to happen.\n\nFrom looking back at my transcripts I think it was this bit that triggered the interrupting laugh:\n\nso where are the owls when they're not, like before dusk? The owls exist, right? Are they hiding in holes? Where are they hiding?\n\nMy longest conversation with the new model has been a full hour while walking the dog (and [taking photos of pelicans](https://simonwillison.net/elsewhere/sighting/)). I have not yet managed to take a photo of an owl.\n\nVia [Hacker News](https://news.ycombinator.com/item?id=48834405)\n\nTags: [text-to-speech](https://simonwillison.net/tags/text-to-speech), [ai](https://simonwillison.net/tags/ai), [openai](https://simonwillison.net/tags/openai), [generative-ai](https://simonwillison.net/tags/generative-ai), [llms](https://simonwillison.net/tags/llms), [multi-modal-output](https://simonwillison.net/tags/multi-modal-output), [llm-release](https://simonwillison.net/tags/llm-release), [speech-to-text](https://simonwillison.net/tags/speech-to-text)", "url": "https://wpnews.pro/news/introducing-gpt-live", "canonical_source": "https://simonwillison.net/2026/Jul/8/introducing-gptlive/#atom-everything", "published_at": "2026-07-08 23:20:48+00:00", "updated_at": "2026-07-08 23:41:15.651595+00:00", "lang": "en", "topics": ["large-language-models", "generative-ai", "ai-products", "ai-tools", "natural-language-processing"], "entities": ["OpenAI", "GPT-Live", "GPT-5.5", "ChatGPT", "GPT-4o"], "alternates": {"html": "https://wpnews.pro/news/introducing-gpt-live", "markdown": "https://wpnews.pro/news/introducing-gpt-live.md", "text": "https://wpnews.pro/news/introducing-gpt-live.txt", "jsonld": "https://wpnews.pro/news/introducing-gpt-live.jsonld"}}
