### 🛠️ Comprehensive CLI & SDK Parameter Reference Manual

The inference runtime provides user-directed controls to eliminate hallucinations and tailor execution to mobile hardware:

| Option Flag | Type / Range | Default | Purpose & Architectural Behavior |
|---|:---:|:---:|---|
| `--prompt-template` | `chatml` \| `falcon` \| `raw` \| `none` | `none` | Wraps user input in model-compliant dialogue tokens to eliminate drift and word salad. |
| `--act-fn` | `auto` \| `relu2` \| `swiglu` | `auto` | Enforces mathematical activation kernel routing (`relu(x)^2` vs `SiLU(x) * up`). |
| `--chunk-layers` | Integer (0 = disabled, e.g. 4) | `0` | Submits GPU command buffers in chunks of N layers, bypassing the 2.5s Mali watchdog fence. |
| `--vocab-slice` | Integer (0 = disabled, e.g. 32768) | `0` | Slices FP16 LM Head projection rows, slashing VRAM consumption by 576MB on 7B models. |
| `-ngl`, `--n-gpu-layers` | Integer (0 to total layers) | `0` | Number of transformer layers permanently offloaded into Vulkan GPU VRAM. |
| `--prompt-prefix` | String | `""` | Custom prefix prepended to user prompt before tokenization. |
| `--prompt-suffix` | String | `""` | Custom suffix appended to user prompt before tokenization. |
| `--eos-token-id` | Integer | Model default | Explicit override for End-of-Sequence token ID to guarantee generation termination. |

## 🚀 Quickstart Recipes

### 1. Python Programmatic Inference
```python
from termux_bitnet import BitNetEngine, BitNetConfig

# Configure for real-time Falcon-E-1B or BitNet-2B with template wrapping
config = BitNetConfig(
    model_path="~/.cache/termux-bitnet/models/falcon-e-1b-instruct-i2_s.gguf",
    device="gpu",           # "auto", "cpu", or "gpu"
    n_gpu_layers=24,        # 100% GPU offload
    chat_template="falcon", # Formats with <|im_start|>user\n...
    chunk_layers=4,         # Prevent Mali watchdog timeouts
    vocab_slice=32768,      # Slashing LM Head VRAM
    n_threads=4,
    temperature=0.7,
    top_p=0.95
)

with BitNetEngine(config) as engine:
    print("[Prompt]: What is the capital of France?")
    print("[Response]: ", end="", flush=True)
    for token in engine.generate_stream("What is the capital of France?"):
        print(token, end="", flush=True)
    print()
    metrics = engine.get_last_metrics()
    print(f"Speed: {metrics.tokens_per_second:.2f} tok/s")
```

### 2. Standalone CLI Usage
```bash
# 1. Run 1B real-time conversational model with Falcon wrapping
termux-bitnet run -m models/falcon-e-1b-instruct-i2_s.gguf \
  -p "What is the capital of France?" --prompt-template falcon -ngl 24 -t 4

# 2. Run Microsoft BitNet 2B with Squared ReLU

## Distributed Clustering & Memory Pooling (AMEVA-Cluster)

Termux-BitNet integrates with **AMEVA-Cluster** (`pip install ameva-cluster`) for distributed 1.58-bit ternary tensor sharding and cross-device memory pooling.

### 1. Install Cluster Runtime
```bash
pip install ameva-cluster
# or Node.js:
npm install @ameva/cluster
```

### 2. Launch Worker Node on Remote Phone
```bash
# On remote worker device (e.g. Galaxy A53):
ameva-cluster worker --port 50052
```

### 3. Run Distributed 1.58-Bit Inference
```bash
# Master node sharding Falcon3-7B or BitNet-2B across remote phones:
termux-bitnet run -m models/bitnet_b1_58-3B.gguf \
  --rpc 192.0.2.10:50052,192.0.2.11:50052 \
  -p "Explain ternary quantization benefits."
```

```python
from termux_bitnet import BitNetEngine, BitNetConfig

config = BitNetConfig(
    model_path="models/bitnet_b1_58-3B.gguf",
    cluster_rpc_servers="192.0.2.10:50052,192.0.2.11:50052"
)
with BitNetEngine(config) as engine:
    for token in engine.generate_stream("Distributed clustering active across ternary nodes."):
        print(token, end="", flush=True)
```
