I Got Tired of Googling "Can My GPU Run This LLM?" So I Built This

The Problem

You want to run LLMs locally (DeepSeek, Llama 3, Mistral, whatever).

You Google: "Can RTX 3060 run Llama 3?"

You get:

  • 10 Reddit threads with different answers
  • Someone says "yeah probably"
  • Someone else says "no way"
  • A YouTube video from 2023

You download 40GB anyway.

It doesn't fit. 😤

The Solution

I built a simple tool that gives you the answer in 5 seconds.

👉 [canirunllms.com](https://canirunllms.com) 👈

How it works:

  1. Pick your GPU
  2. See which models work (green = yes, red = no)
  3. Done.

That's it.

Why I Built This

I was buying a GPU for AI stuff and had no idea what I needed.

Questions I couldn't answer:

  • Will my RTX 3060 run Llama 3?
  • Do I need 16GB or 24GB VRAM?
  • Can my MacBook run local LLMs?
  • What about DeepSeek-R1?

Every answer I found online was "it depends" or "maybe".

So I built a database of every GPU and every popular LLM, and made it searchable.

What Makes This Different

Other tools:

  • Require you to understand "quantization levels"
  • Show you complicated formulas
  • Don't include Apple Silicon
  • Haven't been updated since 2023

This tool:

  • ✅ Just shows you: YES or NO
  • ✅ Covers 50+ models (DeepSeek, Llama, Mistral, Mixtral, Gemma, etc.)
  • ✅ Includes MacBook Pro, Mac Studio, RTX 3060, 4090, AMD, Intel—everything
  • ✅ Updated February 2026
  • ✅ 100% free, no signup

Examples (Try These)

"Can RTX 3060 run DeepSeek-R1 8B?"
👉 Click here
Answer: Yes (4-bit quantized)

"Can RTX 4090 run Mixtral 8x7B?"
👉 Click here
Answer: No (needs 90GB VRAM)

"RTX 4090 vs RTX 3060 – which is better for LLMs?"
👉 Compare them

Who This Is For

You should use this if:

  • 🛒 You're buying a GPU and want to know what you can run
  • 💻 You already have a GPU and want to know which models fit
  • 🍎 You have a Mac and everyone online only talks about NVIDIA
  • 🤔 You're tired of Googling and getting vague answers

Real Use Cases

Before buying a GPU:

"I'm choosing between RTX 4070 and RTX 4090. Let me check which models each one can run..."

Before downloading a 40GB model:

"Wait, will Llama 3 70B even fit on my GPU? Let me check first..."

When someone asks you "what GPU do I need?":

"Just go to canirunllms.com and type in your model. Done."

The Best Part: It's Free

No signup. No email. No credit card.

Just a tool that answers one question:

"Can my GPU run this LLM?"

I'd Love Your Feedback

Since you're here, I have 3 quick questions:

  1. Did you ever download an LLM that didn't fit on your GPU? (I did this 3 times before building this tool 😅)

  2. What GPU do you use? (Curious what the Dev.to crowd runs)

  3. Missing anything? (GPUs, models, features?)

P.S. If this saved you from buying the wrong GPU or downloading a model that doesn't fit, share it with someone who needs it. 🙏
