Not sure what you have? Help me checkTwo numbers decide it: memory, and whether there is a graphics card

On a Mac

Click the Apple logo in the top-left corner of the screen, then About This Mac. Note the Chip (M1, M2, M3, M4…) and the Memory (8 GB, 16 GB…).

On Windows

Press Ctrl + Shift + Esc to open Task Manager, then Performance. Memory shows your RAM. If a GPU entry lists Dedicated GPU memory of 4 GB or more, you have a graphics card; otherwise you don’t.

Then pick the closest match — or the Build your own setup option below for anything else:

Still unsure? Start with the 16 GB laptop: what runs there runs on almost any recent computer.

Why this one: a general chat model that fits this machine without spilling out of memory, answers faster than you read, and has the strongest benchmark results among those that do.

Now run it

Easiest: LM Studio free desktop app, no terminal

  1. Download LM Studio from lmstudio.ai, install it and open it.
  2. Open the search tab (the magnifying glass) and search for unsloth/Qwen3-30B-A3B-GGUF.
  3. Choose the Q4_K_M download (17.4 GiB) and click Download.
  4. Go to the chat tab, pick Qwen3 30B-A3B at the top, and type your first message.

In a terminal: Ollama one command

  1. Install Ollama from ollama.com/download.
  2. Open a terminal and run:
    ollama run hf.co/unsloth/Qwen3-30B-A3B-GGUF:Q4_K_M
    The first run downloads the model (17.4 GiB); then type a message and press Enter.

Runs with partial offload to system RAM 3

Too big for accelerator memory alone; part of it runs from system RAM, which is much slower.

How this is calculatedMemory, fit and speed estimates

Memory = download size + fp16 KV cache for 8K tokens + runtime overhead. Usable memory is 95% of dedicated VRAM, a device-specific share of unified memory (75% by default), and 80% of system RAM for runtimes that can offload. Runtimes must load the file format and support a backend present on the hardware.

Estimated speed is bounded by memory bandwidth ÷ bytes read per token (active parameters for mixture-of-experts), shown in italics with an estimate label and a ±35% range (hover for it). Measured speeds are medians of reference results and verified public community runs on the same system, download and runtime. For each model we recommend the highest-precision download that fits, preferring not to offload.
