Devstral Small 2 24B Instruct 2512 — Hardware Requirements & GPU Compatibility

ChatFunctions

Devstral Small 2 24B Instruct is Mistral AI's dense 24-billion-parameter model for agentic software-engineering work, fine-tuned to follow instructions for chat, coding agents, and tool-heavy workflows. Built on the same architecture as Ministral 3, it adds vision capabilities for analyzing images alongside code and text, and its publisher designed it specifically to be lightweight enough for local, on-device use rather than requiring a large server. It supports a context window of roughly 384,000 tokens and is released under the Apache 2.0 license. Mistral notes it is light enough to run on a single RTX 4090 or a Mac with 32GB of RAM, consistent with its 4-bit memory needs of around 14GB.

Run Devstral Small 2 24B Instruct 2512

18.1 GB VRAM at 16K context · fits the RTX 4090 (5.9 GB free)

Works on macOS, Windows and Linux.

Install Ollama (Linux)
$curl -fsSL https://ollama.com/install.sh | sh
Install Ollama (macOS / Windows)
Download and run the app; it installs the ollama command.
Download Ollama ↗
Run Q4_K_M
$ollama run devstral-small-2:24b
Official Ollama library build. For the exact Q4_K_M file from unsloth/Devstral-Small-2-24B-Instruct-2512-GGUF: ollama run hf.co/unsloth/Devstral-Small-2-24B-Instruct-2512-GGUF:Q4_K_M
Raise the context window
Type it inside the chat. For the API server instead, start it with OLLAMA_CONTEXT_LENGTH=16384 ollama serve.
$/set parameter num_ctx 16384
A larger context needs more memory than the weights alone.
Use the API
Ollama serves its API on http://localhost:11434.

Works on macOS, Windows and Linux.

Install LM Studio
Desktop app for macOS (Apple silicon), Windows and Linux.
lmstudio.ai ↗
Download the model
In the app press Ctrl/Cmd + Shift + M and search mistralai/devstral-small-2-2512, then pick Q4_K_M. Or use the CLI (run LM Studio once first):
$lms get mistralai/devstral-small-2-2512@q4_k_m
Open on Hugging Face ↗
Load and chat
Open the model loader, select the model and set Context Length to 16384. Leave GPU offload at maximum if it fits.

Frequently Asked Questions

How much VRAM does Devstral Small 2 24B Instruct 2512 need?

Devstral Small 2 24B Instruct 2512 requires 15.1 GB of VRAM at Q4_K_M, or 48.7 GB at BF16. Full 393K context adds up to 80.1 GB (95.2 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 24.0B × 4.8 bits ÷ 8 = 14.4 GB

KV Cache + Overhead ≈ 0.7 GB (at 2K context + ~0.3 GB framework)

Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.

KV Cache + Overhead ≈ 80.8 GB (at full 393K context)
