AURA — v1 (LoRA adapter)
A Hinglish system-agent that controls your PC — built from scratch on free Kaggle GPUs.
"bhai chrome kholo" — and the computer obeys.
What is this?
A LoRA adapter for Sarvam-2B (India's open-source LLM, Apache 2.0) that turns it into AURA — a system agent that understands Hindi, Hinglish and English commands and executes real actions on the machine:
| Skill | What it does |
|---|---|
| 📁 Aura Manager | create / save / delete / move / organize files |
| 📦 Aura Installer | install & uninstall software (guarded) |
| 🚀 Aura Launchpad | open apps, websites, browser searches |
| 🔍 Aura Researcher | web search & page fetch |
| 🧮 Aura Aryabhatta | math via a Python sandbox |
| ⚙️ Aura Controller | screenshots, clipboard, volume, system info |
Plus personality: AURA replies in natural Hinglish, and knows when to just talk instead of calling a skill.
Safety design
- Destructive commands (delete, install, format) require explicit user confirmation
- Installer downloads are restricted to an official-domains allowlist
- Dangerous patterns (
rm -rf /,format, fork bombs...) are hard-blocked - The Python sandbox has a blocklist + timeout
Training
| Method | QLoRA (r=16, alpha=32) + NEFTune (alpha=5) + prompt-masked loss |
| Data | 6,687 examples — 6 skills + chitchat, 3 languages (Hindi / Hinglish / English), incl. multi-turn [TOOL RESULT] → confirmation patterns |
| Hardware | Free Kaggle T4 x2 — total GPU budget: ₹0 |
| Loss | 1.77 → 0.0072 in 160 steps (converged; a 250x drop) |
This checkpoint: step-164 draft of the first run. The official full 1-epoch run + router-accuracy eval is on the way and will replace this.
Usage
The full agent runtime (skills, guardrails, execution loop, self-healing) lives in the open-source one-file repo — download AURA_onefile.py and run:
python AURA_onefile.py agent --model sarvamai/sarvam-2b --adapter ./aura_lora
To load the adapter yourself:
from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel
base = AutoModelForCausalLM.from_pretrained("sarvamai/sarvam-2b", device_map="auto")
model = PeftModel.from_pretrained(base, "jhalakdev67dev/aura-v1-lora")
tok = AutoTokenizer.from_pretrained("jhalakdev67dev/aura-v1-lora")
Note: the adapter expects the AURA system prompt (see
build_system_prompt()in the one-file repo) — plain chat without it will still work but the skill-routing is trained for the agent format.
Honest limitations
- 2B parameter model — simple tasks (files, launch, math, search) route reliably; complex multi-step chains are still learning
- English-only tokenizer inherited from the base model's vocab — Hindi is handled through transliteration-friendly Hinglish
- Not a hard security boundary — the sandbox stops accidents, not determined attackers
