Originally created by @zamiere on GitHub (Apr 3, 2026).
Original GitHub issue: https://github.com/ollama/ollama/issues/15269

What is the issue?

ollama show gemma3:4b --modelfile

The current template part is:
TEMPLATE {{ .Prompt }}
There is no complete example at https://ollama.com/library/gemma4
In previous versions we were able to mod template parts, now written that "Note that Ollama already handles the complexities of the chat template for you." - It is not explained in detail what this is about.
Complete template is necessary to disable thinking behaviour with removing <|think|> part.

Relevant log output

Ollama version

Most new models do not use TEMPLATE, the parser and renderer are in code because it's easier. You can remove the RENDERER and PARSER elements from the Modelfile and add your own TEMPLATE by translating the Jinja template to Go template.

Unfortunately, it doesn’t take the Go-converted template into account when the renderer/parser is disabled.

"/set nothink" works well on terminal in chat mode, but there is no equivalent option in Ollama app.
