Notion Adds GPT-6 Astra as a Model Option
GPT-6 Astra is now available in Notion. You can choose it directly in the Notion Agent and Custom Agent model pickers.
How to use it: open Agent or Custom Agent → click the model name → choose GPT-6 Astra.
If you are in China and Astra is missing from the list: go to Settings → Billing, change the billing address to the United States, save, refresh, then check the model picker again. This is a common community workaround.
After Notion added the GPT-5.4 series and Kimi K2.6, the picker has one more option.
