hi there, ollama supports thinking is really nice. while I tested and found that the thinking seems does not support the model create from ollama modelfile.
I'm not sure if it is ture, if I'm wrong, pls correct me. thanks.

for instance, I just created a model(test-deepseekr1:7b) by modelfile from deepseek-r1:7b, and tested the api, just as follwing:
curl http://localhost:11434/api/chat -d '{

"model": "test-deepseekr1:7b",
"messages": [
    {
        "role": "user",
        "content": "有多少个s在strawberrys里面"
    }
],
"think": true,
"stream": true

}'
{"error":"registry.ollama.ai/library/test-deepseekr1:7b does not support thinking"}

then failed.

and if it really does not support this scenario, any plan for this ? or I miss something, how to configure or run it ?
thanks for help in advance.

@rick-github like this : TEMPLATE """{{- if .System }}{{ .System }}{{ end }}
{{- range $i, $_ := .Messages }}
{{- last := eq (len (slice .Messages $i)) 1}}
{{- if eq .Role "user" }}<｜User｜>{{ .Content }}
{{- else if eq .Role "assistant" }}<｜Assistant｜>{{ .Content }}{{- if not $last }}<｜end▁of▁sentence｜>{{- end }}
{{- end }}
{{- if and $last (ne .Role "assistant") }}<｜Assistant｜>{{- end }}
{{- end }}"""

Thinking needs a template that supports it, see https://ollama.com/library/deepseek-r1:7b/blobs/c5ad996bda6e.
