Changed

  • Updated models and usage limits in ChatGPT Voice
  • ChatGPT Voice can now use GPT-5.6 or GPT-6 Astra when it needs to search or reason through harder questions. Choose your model and reasoning effort using the same controls as text chat. Available models and their usage limits depend on your plan.
  • We’re also simplifying GPT-Live daily usage limits:
  • Go: Up to 3 hours with GPT-Live-1 mini, replacing GPT-Live-1 access.
  • Plus: Up to 3 hours with GPT-Live-1.
  • Pro ($100/month): Up to 15 hours with GPT-Live-1.
  • Pro ($200/month): Unlimited GPT-Live-1 usage.
  • Plus and Pro no longer switch to GPT-Live mini after reaching a Voice limit.
  • With these updates, the separate Instant/Medium/High Voice intelligence levels are deprecated.

  • Share files and folders from your Library
  • Library sharing lets you share files and folders in ChatGPT, choose who can access them, and work with shared content directly in your conversations.
  • Share with specific people. Invite recipients and assign Viewer or Editor access.
  • Share across your workspace. Make content available to everyone in your workspace.
  • Manage access. Review who has access, change permissions, or remove access from the sharing dialog.
  • Find and use shared content. Access items in Shared with me and use shared files in conversations with ChatGPT.
  • Shared folders and ownership
  • Files uploaded to a shared folder belong to the folder’s owner. The person who uploaded each file is still recorded.
  • If you upload a file to someone else’s shared folder and they later remove your folder access, the file stays in their folder and you lose access to it.
