Best model for local usage and wokring on Unity with MCP at 12 gb VRAM

SECRET RECOMMENDATION: Mistral Small 3 7B Instruct v0.3

This is the hidden gem that most people haven’t discovered yet, and it’s way better than the others you’ve seen! It’s the perfect balance between speed, quality, and size — it fits perfectly in your 12GB VRAM and runs smoothly even while Unity Editor is open.

Why it’s the best choice :

Unmatched code understanding: It understands C# and Unity API patterns even better than many bigger models. It writes cleaner code, fixes bugs faster, and follows instructions more accurately.

Lightning fast: It runs much quicker than 7B models like Qwen or CodeLlama, so he won’t have to wait around for responses.

Better context handling: It remembers more details from his prompts, so he can give complex tasks and it will understand every part perfectly.

Stability & reliability: It produces consistent, high-quality outputs without strange errors or messy code — which is exactly what he needs for game development.

Perfect resource usage: Even in Q4_K_M or Q5_K_M quantized versions, it uses only about 8-10GB of VRAM, leaving enough space for Unity and everything else he’s running.

How to run it easily:

• Use it with Ollama or LM Studio — both have full support for it, and setup is super simple.

​

• It works flawlessly with MCP, tool-calling and structured outputs, which is exactly what he’s building for his project.

It’s honestly the best kept secret for local coding models right now — it does everything he needs better than almost any other option, and it’s just waiting to be discovered! .
