# Nemotron 3 Nano 4B — Power Apps Formula Expert

A fine-tuned version of [NVIDIA Nemotron 3 Nano 4B](https://huggingface.co/nvidia/NVIDIA-Nemotron-3-Nano-4B-BF16) specialized in **Microsoft Power Apps formula generation, error diagnosis, and SharePoint integration patterns**.

## Model Details

| Attribute | Details |
|---|---|
| **Developed by** | [DevNexAI](https://huggingface.co/Devnexai) |
| **Base model** | NVIDIA Nemotron 3 Nano 4B (Hybrid Mamba-Transformer MoE) |
| **Fine-tuning method** | QLoRA (4-bit) via [Unsloth](https://github.com/unslothai/unsloth) |
| **LoRA rank** | 16 |
| **LoRA alpha** | 32 |
| **Training hardware** | NVIDIA A100-SXM4-40GB (Google Colab Pro) |
| **Precision** | BF16 |
| **License** | Apache 2.0 |
| **Languages** | English, Spanish |

## What This Model Does

This model is trained to assist Power Apps developers with:

- **Formula generation** — Describe what you need in natural language, get the correct Power Apps formula
- **Error diagnosis** — Paste your broken formula, get the root cause and fix
- **SharePoint patterns** — Delegation-aware queries, Patch operations, Choice/Lookup column handling
- **Regional syntax** — Understands separator differences between English (`,`) and Spanish (`;`) environments
- **Best practices** — Named Formulas, Concurrent loading, batch Patch, role-based visibility

## Training Data

The model was fine-tuned on **202 curated examples** across 5 categories:

| Category | Examples | % |
|---|---|---|
| Error/Debugging | 71 | 35.1% |
| Formula generation | 61 | 30.2% |
| Patterns/How-to | 56 | 27.7% |
| SharePoint specific | 10 | 5.0% |
| Explanation | 4 | 2.0% |

## Usage

### With Unsloth (recommended)

```python
from unsloth import FastLanguageModel

model, tokenizer = FastLanguageModel.from_pretrained(
    "Devnexai/nemotron3-powerapps-formulas",
    load_in_4bit=True,
    trust_remote_code=True,
)
FastLanguageModel.for_inference(model)

messages = [
    {"role": "system", "content": "Eres un experto en Power Apps. Genera fórmulas correctas, explica errores y ayuda a resolver problemas de sintaxis."},
    {"role": "user", "content": "Filtra la lista Empleados donde el departamento sea Ventas y el estatus sea Activo"},
]

inputs = tokenizer(
    tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True),
    return_tensors="pt"
).to("cuda")

outputs = model.generate(**inputs, max_new_tokens=512, temperature=0.7, top_p=0.9)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:], skip_special_tokens=True))
```

### With vLLM (API server)

```bash
vllm serve unsloth/NVIDIA-Nemotron-3-Nano-4B-BF16 \
    --enable-lora \
    --lora-modules powerapps=Devnexai/nemotron3-powerapps-formulas
```

## Example Prompts

| Prompt | Category |
|---|---|
| `Filtra pedidos con monto mayor a 10000 y estatus Pendiente` | Formula generation |
| `Error: Filter(Lista, Status = "Activo") me marca error de tipo` | Error diagnosis |
| `Cómo hago una búsqueda delegable en SharePoint por múltiples campos` | SharePoint pattern |
| `Mi Patch no guarda datos, no da error pero no se actualiza` | Silent error debugging |
| `Copié una fórmula de internet y no funciona: If(x > 1, "Sí", "No")` | Regional syntax |

## Limitations

- Trained on 202 examples — increasing to 500+ will improve quality
- Optimized for SharePoint as datasource; Dataverse patterns are limited
- GGUF export not available yet (Mamba-Transformer hybrid not supported by llama.cpp)
- Requires Linux or WSL2 for local deployment (mamba_ssm dependency)
