How to get context window size & other model properties

[Colin Mummery]

I have Nano working consistently well in my SPA using the Prompt and Rewriter APIs. What seems to have changed is the capabilities function which doesn't seem to exist anymore, even Gemini 3.0 seems to have no clue how to find out the properties and values that the capabilities function used to return. Is there still a way to do this or are these properties now hidden? Some example code is always welcome.
