Build a Low-Footprint AI Coding Assistant with Mistral Devstral

In this Ultra-Light Mistral Devstral tutorial, a Colab-friendly guide is provided that is designed specifically for users facing disk space constraints. Running large language models like Mistral can be a challenge in environments with limited storage and memory, but this tutorial shows how to deploy the powerful devstral-small model. With aggressive quantization using BitsAndBytes, cache management, and efficient token generation, this tutorial walks you through building a lightweight assistant that’s fast, interactive, and disk-conscious. Whether you’re debugging code, writing small tools, or prototyping on the go, this setup ensures that you get maximum performance with minimal footprint.

!pip install -q kagglehub mistral-common bitsandbytes transformers --no-cache-dir
!pip install -q accelerate torch --no-cache-dir


import shutil
import os
import gc

The tutorial begins by installing essential lightweight packages such as kagglehub, mistral-common, bitsandbytes, and transformers, ensuring no cache is stored to minimize disk usage. It also includes accelerate and torch for efficient model loading and inference. To further optimize space, any pre-existing cache or temporary directories are cleared using Python’s shutil, os, and gc modules.

def cleanup_cache():
   """Clean up unnecessary files to save disk space"""
   cache_dirs = ['/root/.cache', '/tmp/kagglehub']
   for cache_dir in cache_dirs:
       if os.path.exists(cache_dir):
           shutil.rmtree(cache_dir, ignore_errors=True)
   gc.collect()


cleanup_cache()
print("                        </div>
