Benchmark Positioning

This positioning reflects the intended performance profile of the fine-tuned model:

• Strong coding performance
• Improved instruction following
• Technical reasoning
• Code generation and debugging
• Multimodal understanding
• Efficient local inference
• Competitive performance relative to significantly larger models

Note: Individual benchmark results may vary depending on evaluation methodology, prompt format, inference parameters, quantization, context length, and hardware. Note: The reference values ​​presented above reflect the use of the recommended generation settings (Temperature 0, Top P 0.95, Top K 40).---

⚙️ Recommended Generation Settings

For the best results, change the default sampling configuration to the following values:

Parameter	Recommended Value
Temperature	0
Top P	0.95
Top K	40
Min P	0.05
Repetition Penalty	1.1
Presence Penalty	Off
Max Tokens	Max

Recommended Configuration

Temperature:          0.1
Top P:                0.95
Top K:                25
Min P:                0.05
Repetition Penalty:   1.1
Presence Penalty:     Off
Max Tokens:           Max

⚠️ Important: For optimal output quality, configure your inference interface with the sampling parameters above.

In particular, Temperature should be set to 0 for the recommended configuration.

Using different generation settings can significantly affect the model's behavior, consistency, determinism, and coding performance.

gemma-4-e4b-it.BF16-mmproj.gguf

This enables supported multimodal inference workflows involving:

• Screenshots
• User interfaces
• Programming environments
• Visual debugging
• Diagrams
• Technical images
• Code displayed in images

🦙 Ollama Note for Vision Models

⚠️ Important: Ollama currently does not support separate mmproj files for vision models in the same way as llama.cpp.

To create an Ollama model from a vision-enabled model, place your Modelfile in the same directory as the appropriate merged BF16 model and run:

ollama create nexora-gemma-4-e4b-coder -f ./Modelfile

Replace nexora-gemma-4-e4b-coder with your preferred model name.
