The engine cannot be loaded on the latest Snapdragon 8 Elite chip phone

I can't use Baduk-AI on my Xiaomi 15 phone

I re-built the app with the latest version of Qualcomm's NPU interface libraries (released today): https://github.com/aki65/aki65.github.io/releases/tag/v1.20.9 .

In the release notes they don't say anything about snapdragon 8 elite support, but there are libs for a new NPU architecture, which weren't included before, so I am optimistic. But for lack of a device with this chipset, I can't test it myself, so you will be the first one world-wide ...

If it works, it would be nice if you could measure the performance. Best way to do this in a reproducible way:

1. Set "numSearchThreads" to 2 in "settings -> edit config"
2. Set "max pondering time per position" to 30 in "settings -> manage time settings"
3. Load the attached sgf file (copy contents and do "Load sgf from clipboard")
4. Tap "ponder", then katago will think for 30 seconds and then stop automatically, so you can divide the visit count shown on top by 30 to get the visits per second

Thank you so much!

Thank you very much for the performance data. Did you use 18b or 28b network ?

18b

18b

What about the latest 28b? Why not use stronger 28b network, even on same time basis (for example 10secs) 28b will beat 18b.

I have expected more performance improvement in comparison to my Snapdragon 8 gen2.

My phone runs at about 540 v/s with 18b, and 195v/s with 28b under the same test conditions given by the author.
