How much memory do I need to run gemma-4-26B-A4B-it-qat-japanese-pruned (Q4_0)?

The file size is 4.58 GB (measured). With a 8,192-token context, the estimated memory including the KV cache is 6.14 GB. The formula is published at https://localllm.az-arte.com/en/guide/memory-calculation.

Does gemma-4-26B-A4B-it-qat-japanese-pruned run in 8 GB, 12 GB, 16 GB or 24 GB of VRAM?

8 GB: up to Q4_0 (est. 8.55 GB); 12 GB: up to Q4_0 (est. 12.6 GB); 16 GB: up to Q4_0 (est. 15.8 GB); 24 GB: up to Q4_0 (est. 15.8 GB) (estimated at 8,192 tokens with an f16 KV cache, files from the most-downloaded source).

What is the command to run gemma-4-26B-A4B-it-qat-japanese-pruned with Ollama?

Run "ollama run hf.co/JMingo/gemma-4-26B-A4B-it-qat-japanese-pruned-GGUF:Q4_0" to use the GGUF on Hugging Face directly. To use another quantization, replace the name at the end.

About gemma-4-26B-A4B-it-qat-japanese-pruned

gemma-4-26B-A4B-it-qat-japanese-pruned is a GGUF model based on JMingo/gemma-4-26B-A4B-it-qat-GGUF on Hugging Face. GGUF files are published by JMingo/gemma-4-26B-A4B-it-qat-japanese-pruned-GGUF. It has about 20.9B parameters, the gemma4 architecture, a maximum context length of 262,144 tokens (values written in the GGUF).

There is one quantization, Q4_0, with a file size of 4.58 GB (actual size on Hugging Face).

Running Q4_0 (4.58 GB) with an 8,192-token context needs an estimated 6.14 GB of memory, and an estimated 6.64 GB at 32,768 tokens. For 8,192 tokens, a GPU with 6 GB or more of VRAM (such as Arc A380, GeForce RTX 4050 Laptop GPU), or a Mac with 6 GB or more of unified memory, is a rough guide (macOS caps how much memory the GPU can use, so leave some headroom).

File sizes are the actual values on Hugging Face. Memory is estimated for each context length (KV cache f16). The formula is in How memory is calculated.

All memory figures are Estimated (KV cache f16). It should run on a setup with at least this much VRAM (or Mac unified memory). Click a value to see the devices and models that fit that amount (Find by GPU / Mac).

About the "quality guide" (how far a quantization drifts from the original)

For each quantization type, how far the output drifts from the original model, grouped into six levels from values llama.cpp measured on Llama-3-8B.

The value is mean KLD (the difference between the original and quantized model in next-token probabilities); smaller means closer to the original. Quantizations made with an imatrix (importance data) come out slightly smaller. Levels use the value without an imatrix (or with one, for types that only have that).

These values were not measured on this model. Larger models and MoE models tend to drift less with the same type. Distributor-specific mixed types (such as UD-Q4_K_XL) cannot be matched by type name alone, so they show "-".

How to run

Mainline llama.cpp can load this model's format (gemma4) from b8637 (Apr 2, 2026) onward. Ollama and LM Studio bundle llama.cpp internally, so an older app fails to load it with errors such as "unknown model architecture". If that happens, update the app.

Example commands using Q4_0. To use another quantization, replace the name with one from the table above. How to run local LLMs

Ollama

Run it by pointing directly at the GGUF on Hugging Face.

ollama run hf.co/JMingo/gemma-4-26B-A4B-it-qat-japanese-pruned-GGUF:Q4_0

llama.cpp

Pass the repository and quantization name to llama-server (or llama-cli) with -hf.

llama-server -hf JMingo/gemma-4-26B-A4B-it-qat-japanese-pruned-GGUF:Q4_0

LM Studio

Paste JMingo/gemma-4-26B-A4B-it-qat-japanese-pruned-GGUF into the search box, download it, and choose the quantization from the file list.
