An OpenAI staffer rounds up this week's ChatGPT updates, including faster image generation, easier file sharing, better location use, and GPT-6 Astra in Voice's higher intelligence mode, which is slow but the most capable.

This week's ChatGPT feature drop - Sept 11: 1/ We upgraded ChatGPT Images: it's much faster, more precise at edits, and better at understanding complex instructions. It's remarkable how much people love generating images, and it's only accelerating! 2/ Two fun features on the iOS app: when you send a message, the animation is faster and smoother. You can also pull down from anywhere in the conversation to start a new chat. 3/ When ChatGPT creates a file for you – a note, a document, a presentation or a spreadsheet – it's now much easier to share it. You can give other email addresses view or edit rights, and they'll see those files in their ChatGPT Library. 4/ We've improved 'location' use in answers (with user permission). A few weeks ago we improved the use of time in answers. Now, "what events are happening in my neighborhood" should be a lot better. 5/ Voice got smarter - When you select the 'higher intelligence' options in Voice, you can now use GPT-6 Astra, our latest frontier model. Warning, it's slow, but it's the best intelligence, hands-free. We're making answers better, and making the app much easier to use! 🚀
