# Nexus-VMC-v1.4-RCL (1.5B) - Unified Strategic Intelligence

Nexus-VMC-v1.4-RCL is a high-performance Small Language Model (SLM) meticulously fine-tuned for the **Antigravity Hub**. It excels in medical reasoning, Excel data logic, and complex tool-calling via the **VMC-RCL (Reasoning-Call-Logic)** protocol.

## Key Features

- **Strategic Reasoning**: Native support for `<vmc_think>` blocks, enabling deep analytical processing before task execution.
- **Precision Tool-Calling**: 100% adherence to `[TOOL_CALL]` JSON schemas in comparative benchmarking.
- **Unified Domain Mastery**: Expert-level performance in Medical clinical reasoning, Excel formula generation (SUMIF, etc.), and Document RAG.
- **Ultra-Efficient Inference**: Optimized for local deployment on 8GB RAM environments (Laptop GPUs, CPU inference).

## Benchmark Results (Phase 1.4 RCL)

Benchmarked against SLM baselines and 9B-class models on a 4070 Laptop GPU (Ollama API).

| Model | Avg TPS | Med Reasoning | Excel Logic | Hub Protocol Adherence |
| :--- | :--- | :--- | :--- | :--- |
| **Nexus-VMC-v1.4-RCL** | **130.3** | **PASS (Strategic)** | **PASS (SUMIF)** | **Native (S-Tier)** |
| hauhau-qwen9b | 37.2 | PASS (Text) | PASS (Text) | B-Tier |
| phi3.5:latest | 94.1 | PARTIAL (Python) | PASS (Formula) | C-Tier |
| qwen2.5:1.5b | 196.4 | FAIL (Manual) | FAIL (Repeated) | D-Tier |

## Usage Examples

### VMC-RCL Protocol
```text
User: 병원의 재원 할당을 최적화하기 위해 현재 환자 수를 분석해줘.

Assistant:
<vmc_think>
환자 수 데이터를 기반으로 한 최적화 분석이 필요함. 
hospital_warehouse 도구를 호출하여 실시간 데이터를 가져오는 논리적 흐름 설정.
</vmc_think>
[TOOL_CALL]
{"name": "mcp_tool", "kwargs": {"target": "hospital_warehouse", "query": "current_patient_census"}}
```

## How to Run locally (Ollama)

1. Download the `nexus-vmc-v1.4.Q8_0.gguf` file.
2. Create a `Modelfile`:
   ```text
   FROM ./nexus-vmc-v1.4.Q8_0.gguf
   TEMPLATE "<|im_start|>user\n{{ .Prompt }}<|im_end|>\n<|im_start|>assistant\n"
   PARAMETER stop "<|im_end|>"
   ```
3. Run `ollama create nexus-v1.4 -f Modelfile`
4. Run `ollama run nexus-v1.4`
