What is the chat template for Ollama ?
When import Qwen3 to Ollama we usually create a modle file with chat template, like below:
TEMPLATE """{{- if .Messages }}
{{- if or .System .Tools }}<|im_start|>system
{{- if .System }}
{{ .System }}
{{- end }}
{{- if .Tools }}
Tools
You may call one or more functions to assist with the user query.
You are provided with function signatures within XML tags:
{{- range .Tools }}
{"type": "function", "function": {{ .Function }}}
{{- end }}
For each function call, return a json object with function name and arguments within XML tags:
{"name": , "arguments": }
{{- end }}<|im_end|>
{{ end }}
{{- range $i, $_ := .Messages }}
{{- $last := eq (len (slice $.Messages $i)) 1 -}}
{{- if eq .Role "user" }}<|im_start|>user
{{ .Content }}<|im_end|>
{{ else if eq .Role "assistant" }}<|im_start|>assistant
{{ if .Content }}{{ .Content }}
{{- else if .ToolCalls }}
{{ range .ToolCalls }}{"name": "{{ .Function.Name }}", "arguments": {{ .Function.Arguments }}}
{{ end }}
{{- end }}{{ if not $last }}<|im_end|>
{{ end }}
{{- else if eq .Role "tool" }}<|im_start|>user
{{ .Content }}
<|im_end|>
{{ end }}
{{- if and (ne .Role "assistant") $last }}<|im_start|>assistant
{{ end }}
{{- end }}
{{- else }}
{{- if .System }}<|im_start|>system
{{ .System }}<|im_end|>
{{ end }}{{ if .Prompt }}<|im_start|>user
{{ .Prompt }}<|im_end|>
{{ end }}<|im_start|>assistant
{{ end }}{{ .Response }}{{ if .Response }}<|im_end|>{{ end }}"""
But for Qwen 3.5,is the the same chat template as Qwen 3 or Qwen 2.5.
I directly pulled Qwen3.5 9b with Ollama, but when I check the model file, there is no chat template, what is going on?
What is the official chat template for Qwen 3.5 ??
Same question here
wow
