Where does my data go when I use GPT-6 Astra on mumo?+
Your prompt and the shared panel context go to OpenAI's API, which runs the model and returns the response. OpenAI is the only recipient for this model's calls — our privacy policy sets out who receives what.
Is my data sent to OpenAI?+
Yes — GPT-6 Astra runs on OpenAI's own API, so your prompts reach OpenAI's servers. Under OpenAI's standard API terms, API traffic isn't used to train their models.
