It's worth noting that AI Studio is the API, it's the same as OpenAI's Playground for example.
I find it maddening that AI Studio doesn't have a way to save the system prompt as a default.
On the top right click the save icon
That's for the thread, not the system prompt.
By me it's the exact opposite. It saves the sys prompt and not the "thread".
Sadly, that doesn't save the system instructions. It just saves the prompt itself to Drive ... and weirdly, there's no AI studio menu option to bring up saved prompts. I guess they're just saved as text files in Drive or something (I haven't bothered to check).
Truly bizarre interface design IMO.
That's weird, for me it does save the system prompt
It definitely saves system prompts and has for some time.
