Original GitHub issue: https://github.com/ollama/ollama/issues/14722

What is the issue?

When creating a Modelfile from Qwen 3.5 (I tested 27b and 122b), I put the
TEMPLATE field as

TEMPLATE """ {{ .System }} """

and then set a SYSTEM field as

SYSTEM """Testy Test."""

to make the model only see the System message and not any user messages.

Next, I started a chat with the model with a simple Hi.
The model was able to see the Hi.

Relevant log output

OS

Linux

GPU

Nvidia

CPU

AMD

Ollama version

0.17.7

The 27b model was tested from a conversion from Safetensors.
The 122b model was pulled from the Ollama Registry.

If you did FROM qwen3.5:27b, then the new model is inheriting the PARSER and RENDERER from the parent model. You can avoid that by specifying the GGUF rather than the model:

ollama show --modelfile qwen3.5:27b | grep "^FROM " > Modelfile
echo 'TEMPLATE """ {{ .System }} """' >> Modelfile
echo 'SYSTEM """Testy Test."""' >> Modelfile
ollama create qwen3.5:14722
ollama run qwen3.5:14722 hi

See #14560 for overriding.

I will wait for it to be fixed then.
Thanks!
