Gemma4All Hardware Checker is a free, no-signup web tool that instantly tells you whether your Mac, NVIDIA GPU, CPU-only PC, or phone can run any of Google's Gemma 4 model sizes locally — and which quantization to use.
What is Gemma4All Hardware Checker?
Gemma4All Hardware Checker is a browser-based utility from the Gemma4All site, a directory of guides for running Gemma 4 on your own hardware. You input your device type (Mac, NVIDIA GPU, CPU-only PC, or phone) and your available memory; the tool outputs a verdict of Comfortable, Tight, or Won't fit for each of the five Gemma 4 models (E2B, E4B, 12B, 26B A4B, and 31B), along with the recommended quantization level. It also provides a memory breakdown and QAT tips, and generates a shareable results link. The tool is free, requires no account, and is designed to be a fast first check before you download gigabytes of model weights.
Key Features
- Instant verdict — Pick your device and memory size; get a Comfortable, Tight, or Won't fit answer for every Gemma 4 model in about 10 seconds.
- All 5 Gemma 4 sizes — Covers E2B, E4B, 12B, 26B A4B (MoE), and 31B, with a recommended quantization (including QAT) for each.
- Wide hardware support — Works for Apple Silicon Macs (MacBook Air, Pro, Mini, Studio), NVIDIA GPUs (RTX 3060, RTX 3070/3080 families), CPU-only PCs, and phones; includes a dedicated page for 44 popular device configurations.
- Memory breakdown — Each result explains why a model fits or doesn't, showing how the model's memory requirement maps to your available RAM/VRAM.
- Shareable results — Generates a unique link for your configuration, so you can save it or send it to someone else.
- Free, no signup — No account, no email, no cost; the roadmap includes support for more open models beyond Gemma 4.
Who is it for?
- MacBook owners — Check whether your Air, Pro, Mini, or Studio's unified memory can run a 12B or 26B model before committing to a download.
- NVIDIA GPU users — See if your RTX 3060, RTX 3070, or RTX 3080 has enough VRAM for the model you want, and which quant keeps you under the limit.
- CPU-only users — Confirm that a Gemma 4 CPU-only setup is possible with your RAM, and which model size (e.g., the 26B MoE) is the best fit.
- Phone owners — Check whether the smallest Gemma 4 models (E2B, E4B) can run on your mobile device's memory.
What can you do with Gemma4All Hardware Checker?
- Pre-download sanity check — Before running
ollama pull gemma4:e4b(a 5.2 GB download, per the site's terminal example), verify that your device actually fits the model, saving bandwidth and time. - Quantization planning — See whether to use Q4_0 or the official QAT quant for your hardware, so you know which command to pass to Ollama, llama.cpp, or LM Studio.
- Hardware comparison — Test two candidate machines (e.g., a Mac mini versus an RTX 3060 desktop) side by side to decide which one best runs your target model size.
- Learning about local AI limits — Use the memory breakdown and per-model verdicts to understand why a 31B model needs 20GB RAM while a 4B model runs in 6GB, making the guide content easier to follow.
Pricing
Free to use, no signup required. The tool has no paid tiers or hidden fees.
FAQ
Is Gemma4All Hardware Checker free?
Yes. The tool requires no signup, no account, and there is no free-tier limit or paid version mentioned on the site.
Which Gemma 4 models does it check?
All five: E2B (2B), E4B (4B), 12B, 26B A4B (MoE), and 31B. Each verdict includes the model's minimum RAM and a recommended quantization.
What does the verdict mean?
The tool classifies your device as Comfortable, Tight, or Won't fit for each model. It also gives a memory breakdown showing how the model's weight size compares to your available RAM/VRAM.
Does it support devices beyond Macs and NVIDIA GPUs?
Yes, it handles CPU-only PCs and phones. The site includes dedicated pages for 44 popular device configurations, covering common Mac and PC models.
Can I check other AI models?
Not yet. The page states that the roadmap includes support for more open models, but currently the checker is Gemma 4-specific.
A good next step is the Can You Run Gemma 4? ✓ page or the Start Learning hub.
