What AI can your computer actually run?

Tell FitCheck about your setup in plain words. It tells you honestly what you can run today, from chatbots to object detection, what it will feel like, and exactly how to start.

Your computer

What kind of computer?

Memory (RAM)

Not sure? See “How do I find my specs?” below.

Graphics (GPU)

Advanced: enter exact numbers

Graphics memory (VRAM), if you know it

Overrides the GPU picker above. Leave blank to use the picker.

Or paste / describe your specs

What do you want to do? (pick one or several)

Have a specific model in mind? (optional)

Checks that exact model with a live Hugging Face lookup (the rest of FitCheck runs fully offline).

What matters most? (optional)

How do I find my specs?

What do these words mean?

Model: The AI’s “brain”. Bigger means smarter, but heavier.
Parameters (e.g. 7B): How big the brain is. 7B is 7 billion. More means smarter and hungrier for memory.
Quantisation (4-bit, 8-bit): Shrinking a model so it fits. 4-bit is the popular sweet spot: much smaller, barely-noticeable quality loss.
VRAM: The fast memory on a graphics card. The biggest factor in what runs quickly.
RAM: Your computer’s normal memory. Models can use it too, but it is slower.
GGUF: A single-file model format made for running locally.
