Using with Stock llama.cpp
If you cannot use Nex's patched llama.cpp, a template-fixed version is available at SC117/Nex-N2-mini-template-fix-APEX-GGUF. These GGUFs have a modified chat_template.jinja embedded so that --reasoning-format works on stock llama.cpp without --chat-template-file.
⚠️ The Nex team explicitly advises against modifying the chat template — the model was trained strictly on the original template, and deviating from the training-time format may degrade output quality. See discussion #3. Use the template-fixed version only if you have no alternative, and be aware of the potential quality trade-off.
