Tool capability is enabled in the model template. Models downloaded from the ollama library have the appropriate template, models from other repos need to have the template added.

echo FROM hf.co/unsloth/Qwen3-Coder-Next-UD-IQ4_NL > Modelfile
ollama show --modelfile qwen3-coder-next:q4_K_M | grep -v FROM >> Modelfile
ollama create qwen3-coder-next:iq4_nl
