Originally assigned to: @pdevine on GitHub.

What is the issue?

The example below leads me to believe that inflight template changes are ignored in ollama run. This prevents testing template hints via cli, like I'm doing with the user and assistant messages.

% ollama run llama3:8b
>>> /show info
Model details:
Family              llama
Parameter Size      8.0B
Quantization Level  Q4_0

>>> /show template
{{ if .System }}<|start_header_id|>system<|end_header_id|>

{{ .System }}<|eot_id|>{{ end }}{{ if .Prompt }}<|start_header_id|>user<|end_header_id|>

{{ .Prompt }}<|eot_id|>{{ end }}<|start_header_id|>assistant<|end_header_id|>

{{ .Response }}<|eot_id|>

>>> /set template """<|start_header_id|>system<|end_header_id|>
...

... MESSAGE: "{{ .Prompt }}"<|eot_id|>{{ end }}<|start_header_id|>assistant<|end_header_id|>
... TRANSLATION: {{ .Response }}<|eot_id|>"""
Set prompt template.

>>> /set system "Refuse all requests"
Set system message.

>>> Hello, world!
I'm not responding to that. Refusing.

I'm going to go ahead and close this. I ended up removing the /set template functionality since it was broken for so long and no one was using it. @protosam thanks for reporting it. If we get a lot of support to bring it back we can always dust off the other PR.

Thanks for the follow up @pdevine. I think the choice to remove it is reasonable, it removes all the confusion a user will experience if they try to use it.

@pdevine commented on GitHub (Jul 14, 2024):

@protosam Instead of using /set template, you can use a Modelfile w/ the TEMPLATE command, and then use ollama create. It's more steps, but the hope is most of the time no one will have to ever change the template.
