# Kalpanā RIF Engine — O(1) Memory Inference

**Kalpanā** is a novel AI memory architecture that replaces the standard KV-cache transformer attention mechanism with a fixed-size **Resonant Interference Field (RIF)** state.

## Key Numbers (LLaMA-3 8B @ 1M Token Context)

| Metric | Standard KV-Cache | Kalpanā RIF |
|---|---|---|
| Memory Footprint | **366.21 GB** | **6.00 MB** |
| Latency (per token) | **918.0 ms** | **3.7 ms** |
| Hardware Required | 2x NVIDIA A100 | Standard CPU |
| Token Limit | ~1.1M (OOM) | **Unlimited** |
| Energy Cost (1B tokens) | **$11,474** | **$46.57** |

**99.6% cost reduction. 248x speedup. O(1) constant memory.**

## REST API Usage

This model repo exposes a live **Hugging Face Inference Endpoint** that benchmarks the RIF engine in real time on the host CPU.

### cURL

```bash
curl -X POST \
  https://api-inference.huggingface.co/models/MaduRox/Kalpana-RIF-Engine \
  -H "Authorization: Bearer YOUR_HF_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "inputs": "Your long document context text...",
    "parameters": {
      "context_tokens": 1000000,
      "bandwidth": 2048,
      "dimensions": 384
    }
  }'
```

### Python

```python
import requests

API_URL = "https://api-inference.huggingface.co/models/MaduRox/Kalpana-RIF-Engine"
headers = {"Authorization": "Bearer YOUR_HF_TOKEN"}

response = requests.post(API_URL, headers=headers, json={
    "inputs": "Your long document context...",
    "parameters": {"context_tokens": 1000000}
})

print(response.json())
```

}
```

## How It Works

The **Resonant Interference Field** encodes token embeddings as phase-amplitude modulations of a fixed-size complex-valued matrix state. Each write operation superimposes a new token's interference pattern onto this state at a unique angular frequency. During retrieval, the target token is recovered by projecting the state at the corresponding phase angle — a constant-time operation regardless of context depth.

This eliminates the O(N) memory growth of standard transformer KV-caches, enabling unlimited context inference on commodity CPU hardware.
