No that seems to be indeed a native part of the multimodal Gemini model. I didn't know this existed, it's not available in the normal Gemini interface.
The (no longer, I guess) industry-leading features people actually want are hidden away in some obscure “AI studio” with horrible usability, while the headline Gemini app still often refuses to do anything useful for me. (Disclaimer: I last checked a couple of months ago, after several more of mild amusement/great frustration.)
