# Load base model + LoRA weights
base_model = AutoModelForCausalLM.from_pretrained(
    config.base_model_name_or_path,
    torch_dtype=torch.float16,
    device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained(config.base_model_name_or_path)

##  Why Alpie Core?

**Alpie Core is one of the first fine-tuned 4-bit reasoning models from India, and among the first worldwide at this scale.** Trained on just 8 Hopper GPUs using LoRA and QLoRA 4-bit quantization with synthetic STEM-rich datasets, it proves that aggressive quantization can match and even surpass full-precision baselines.

With a dramatically reduced memory footprint, Alpie Core delivers competitive, frontier-level reasoning performance, even beating top proprietary models. It achieves:

- **81.28% on MMLU** (5-shot)
- **92.75% on GSM8K** (8-shot)  
- **57.8% on SWE-Bench Verified** (ranked #1 globally)

This demonstrates that efficient models can rival frontier systems while remaining practical for real-world deployment at scale.

##  Approach

**Alpie Core** underwent extensive **supervised fine-tuning (SFT)** to strengthen reasoning, robustness, and safety. The training leveraged a diverse mixture of curated open-source datasets and proprietary synthetic data, optimized with high-quality LLM-generated responses. The fine-tuning process emphasized:

1. **User Understanding and Clarity** – ensuring outputs are direct, interpretable, and pedagogically sound

## Environmental Impact

![Carbon Footprint](carbon_footprint.png)

We estimated the carbon footprint of training Alpie Core on 8× NVIDIA H100-80GB GPUs:

**Formula**: CO₂e (kg) = Grid CO₂ Factor × Runtime × Power per GPU × Number of GPUs

**Training Parameters**:
- Grid CO₂ Factor (Azure): 0.364 kg CO₂e/kWh
- Runtime: 408 hours
- GPUs: 8× H100-80GB

**Results**:
- **Realistic mode** (250W avg per GPU): **~298 kg CO₂e**
- **Conservative mode** (700W TDP per GPU): **~835 kg CO₂e**

*This makes Alpie Core one of the most carbon-efficient reasoning models released to date.*

## Safety and Limitations

### Enhanced Content Access

Unlike the base DeepSeek model, Alpie Core provides factual, balanced responses to geopolitically sensitive questions, offering global accessibility on topics like Taiwan's status, Arunachal Pradesh sovereignty, and other sensitive issues.

### Current Limitations

- Multilingual reasoning in Hindi/Hinglish shows room for improvement
- Fixed knowledge cutoff without real-time information retrieval
- Occasional struggles with complex multi-hop mathematical reasoning
- Potential hallucinations in factual question-answering
- Should not be used for medical/legal advice without expert oversight

### Mitigations

- Safety classifiers and output filtering systems
- Model-assisted safety pipeline using RLHF
- Comprehensive adversarial testing by domain experts
