Pixel Recorder’s Gemini Nano-powered

1GB download required for Pixel Recorder’s Gemini Nano-powered ‘Summarize’ 

In addition to Gboard Smart Reply, Gemini Nano on the Pixel 8 Pro powers a “Summarize’ feature in Recorder. Summarize requires an update to Recorder 4.2.20231031.x, which contains several strings detailing how it will work. Google explains that “Pixel Recorder uses a large language model to summarize your transcript content” and you must “Download model to continue.” If you are not on Wi-Fi, then you will have a “This update requires 1GB of mobile data” message. 

Gemini Nano comes in two versions: “1.8B (Nano-1) and 3.25B (Nano-2) parameters, targeting low and high memory devices respectively.” Android AICore is presumably involved in the download process. We have not been able to get Summarize running. People do see the “Summarize” button at the top of some longer transcriptions, but it always returns a “Transcript is too long” message: “Summarization works best with medium-length transcripts.”

However, it consistently doesn’t work and message might be a bug related to how the model has not rolled out/been downloaded yet. It’s not clear how you manually trigger the download. There should also be a “Transcript is too short” prompt. We have not seen the Summarize button in sessions which are shorter in length.
