# Edge Command Model — EVE-OS & Linux Terminal Assistant

A fine-tuned [Qwen3-0.6B](https://huggingface.co/Qwen/Qwen3-0.6B) model trained to act as a lightweight command assistant for EVE-OS edge devices and Linux systems. It accepts natural language requests and responds exclusively with structured JSON tool calls.

## Intended Use

This model runs on edge hardware (ARM or x86 CPU, no GPU required) and serves as an on-device command assistant for operators managing EVE-OS edge nodes. It is designed for offline, air-gapped, or bandwidth-constrained environments where cloud-based LLMs are not available.

**Example interaction:**

```
User: Show memory usage
Model: {"tool": "terminal", "command": "free -h"}

User: What is zedagent?
Model: {"tool": "explain", "text": "zedagent is the main EVE-OS orchestration agent. It processes configurations from ZedCloud, manages application deployment, handles device attestation, and coordinates all other EVE services."}
```

## Output Format

The model always responds with a single JSON object in one of two formats:

**Terminal commands** (for actions to execute):
```json
{"tool": "terminal", "command": "<shell command>"}
```

**Explanations** (for informational queries):
```json
{"tool": "explain", "text": "<explanation>"}
```

## Training Details

| Parameter | Value |
|---|---|
| Base model | Qwen/Qwen3-0.6B |
| Method | QLoRA (4-bit quantization during training) |
| LoRA rank (r) | 32 |
| LoRA alpha | 64 |

| Learning rate | 1e-4 |
| Scheduler | Cosine |
| Epochs | 15 |
| Max sequence length | 512 |
| Training examples | 1,715 |
| Training hardware | Single consumer GPU |

## Performance

Tested against 100 randomly sampled prompts from the training set.

JSON Validity Rate: 99.3%
Tool Routing Accuracy: 98.6%
Exact Match Accuracy: 20.0%
Fuzzy Match Accuracy: 27.6%
Average Inference Time: 0.692s per query
Peak Memory Usage: 736.0 MB

## Training Data

The model was trained on 1,715 instruction-output pairs covering:

- **~350 unique commands** with 4-5 phrasing variations each
- **Linux commands**: file operations, text processing, networking, process management, disk/storage, kernel modules, containers (containerd/runc), ZFS, LVM, security, namespaces, cgroups
- **EVE-OS commands and concepts**: all pillar microservices (zedagent, nim, domainmgr, zedrouter, volumemgr, etc.), device filesystem paths (/persist, /config, /run), ZedCloud connectivity, EdgeView, TPM management, containerd operations
- **Explanations**: EVE-OS architecture, Linux subsystems, file paths, configuration files

All training data was human-curated and reviewed for accuracy.

## Quantization

The model is provided in GGUF format quantized to **Q4_K_M** for efficient CPU-only inference.

| Format | File Size | RAM Required | Use Case |
|---|---|---|---|
| Q4_K_M (recommended) | ~450 MB | 2-4 GB | Edge deployment, CPU inference |
| Q8_0 | ~700 MB | 4-6 GB | Higher accuracy, more RAM available |
| F16 | ~1.2 GB | 6-8 GB | Maximum accuracy, development/testing |

## Hardware Requirements

**Minimum:**
- CPU: Any modern ARM or x86 processor
- RAM: 2 GB
- Storage: 500 MB
- GPU: Not required

**Recommended:**
- CPU: ARM Cortex-A72 or better / x86-64
- RAM: 4 GB
- Storage: 1 GB

Tested on Raspberry Pi 4 (4GB) and x86 edge gateways.

## How to Use

### With llama.cpp

```bash
./llama-cli -m edge-command-model-Q4_K_M.gguf \
  --temp 0.1 \
  --top-p 0.9 \
  -p "<|im_start|>system
You are an edge device command assistant. You respond ONLY with valid JSON tool calls. Never respond with plain text. Available tools: terminal, explain.
<|im_end|>
<|im_start|>user
Show disk space
<|im_end|>
<|im_start|>assistant
"
```

### With Ollama

Create a Modelfile:
```
FROM ./edge-command-model-Q4_K_M.gguf
SYSTEM "You are an edge device command assistant. You respond ONLY with valid JSON tool calls. Never respond with plain text. Available tools: terminal, explain."
PARAMETER temperature 0.1
PARAMETER num_ctx 512
```

Then:
```bash
ollama create edge-cmd -f Modelfile
ollama run edge-cmd "Show memory usage"
```

### With llama-cpp-python

```python
from llama_cpp import Llama

model = Llama(model_path="edge-command-model-Q4_K_M.gguf", n_ctx=512, n_threads=4)

prompt = """<|im_start|>system
You are an edge device command assistant. You respond ONLY with valid JSON tool calls. Never respond with plain text. Available tools: terminal, explain.
<|im_end|>
<|im_start|>user
Show memory usage
<|im_end|>
<|im_start|>assistant
"""

output = model(prompt, max_tokens=128, temperature=0.1, stop=["<|im_end|>"])
print(output["choices"][0]["text"])
```

## Coverage

The model covers commands and concepts across these categories:

**Linux:**
File operations, text processing (grep, sed, awk), networking (ip, ss, tcpdump, iptables), process management, disk/storage (lsblk, fdisk, ZFS, LVM), kernel modules, containers (containerd, runc), security (namespaces, cgroups, capabilities), compression, certificates (openssl), WireGuard

**EVE-OS:**
All pillar microservices (zedagent, nim, domainmgr, zedrouter, volumemgr, baseosmgr, tpmmgr, vaultmgr, loguploader, ledmanager, nodeagent, and more), device filesystem layout (/persist, /config, /run), ZedCloud communication, EdgeView remote diagnostics, containerd operations on EVE, ZFS pool management, device identity and certificates

## Limitations

- The model is trained on a fixed set of ~350 commands. It may hallucinate plausible but incorrect commands for requests outside its training distribution.
- Explain responses are generated, not memorized. Factual accuracy of explanations should be verified for critical operations.
- The model does not support multi-turn conversation. Each request is independent.
- Complex compound commands (multi-pipe chains) may be less accurate than single commands.
- The model was trained for EVE-OS specifically and may not generalize well to other edge operating systems.

## Safety

This model is intended to be used behind an agent harness that:
- Requires user confirmation (y/n) before executing any terminal command
- Blocks dangerous commands (rm -rf /, mkfs on mounted volumes, fork bombs)
- Enforces timeouts on command execution
- Limits output capture size

**Never execute model outputs directly without human review.**
