?? Why Devstral 24B Is a Must-Have for RTX 4090 Developers
Tired of AI models that can't handle real-world coding chaos? Meet Mistral Devstral 24B—the open-source coding agent designed to tackle software engineering headaches head-on. Built with Apache 2.0 licensing, this 24B-parameter model runs flawlessly on RTX 4090 GPUs and even 32GB RAM Macs, offering enterprise-grade performance at zero licensing cost. From bug fixes to automated code refactoring, Devstral redefines what an AI coding partner can do.
??? How to Get Started with Devstral 24B on RTX 4090
Step 1: Download & Deploy
Grab the model from Hugging Face or Ollama (). For RTX 4090 users, load the model with 40GB VRAM:
ollama run devstral
Pro Tip: Use ollama run devstral:q4_0 for lower memory usage.
Step 2: Integrate with OpenHands
Devstral shines with OpenHands, a coding agent framework. Install it via:
pip install openhands
Configure your project directory and let Devstral navigate your codebase like a pro.
Step 3: Benchmark Your Setup
Run the SWE-Bench Verified test to see Devstral's 46.8% problem-solving score in action (). Compare it to GPT-4.1-mini (23.6%) and Claude 3.5 Haiku (40.6%)—Devstral steals the show!
Step 4: Automate Tedious Tasks
Use Devstral to:
Fix security vulnerabilities in legacy code
Generate PR documentation from commit messages
Refactor spaghetti code into modular components
Step 5: Optimize for Production
Fine-tune Devstral on your internal codebase using LoRA adapters. Mistral provides unsloth integration for seamless training:
from unsloth import FastLanguageModel
model = FastLanguageModel.from_pretrained("mistralai/Devstral-Small-2505", device_map="auto")
