Note that 3.5 9B cannot do thinking (while 3.6 27B can, pretty effectively, quite verbosely).

3.5 9B can do thinking. Its just disabled by default in its gguf chat template.

It is disabled because it doesn't work :) Try it and see the doom loop it gets itself in.

I had no failure mode in 3.6 9B thinking with llama.cpp. After release, there were updates for both model and llama.cpp.
