docker model package don't update context size

[Glog78]

docker model ls
docker model rm gemma4:12B_256k
docker model package --from ai/gemma4:12B --context-size 262144 gemma4:12B_256k

expected result changed context window size

i also trying to change the context window size for DMR models.
didnt found any in the UI.

from Docker desktop > Models > Docker Hub
i pulled the latest Gemma4 model. the one with 7.52B parameters and size 4.74GiB
also cant success to change the context-size.

GPT says trying to use command like this:
docker model configure --context-size 131072 ai/gemma4 ?

did you try it?

[Glog78]

Yes i tried the second command too but this also doesn't update the ctx (and most likely used) context size.

on a sidenote it worked before the latest updates as you can see in the repackage's of gemma4:latest_256k in the original screenshot ;)

I can confirm this is a problem for me as well. client v1.2.1, engine v1.2.3 on Debian WSL2. Had to spend a lot of time scratching my head as to why I couldn't change context size for the Qwen3.5-35B. I'm on llama.cpp for now, but if the fix arrives I will switch back over.
