Can the DGX Spark (GB10) run Gemma 4 26B A4B?
Yes. Gemma 4 26B A4B fits the DGX Spark (GB10)'s 128 GB at Q4_K_M (about 16.8 GB needed), running at an estimated 46 tok/s. There's room for up to FP16 if you want higher quality.

| Quant | Weights | Needs | Fit | Est. speed |
|---|---|---|---|---|
| Q4_K_M | 15 GB | 16.8 GB | Fits easily | ~46 tok/s |
| Q5_K_M | 19 GB | 20.8 GB | Fits easily | ~36 tok/s |
| Q8_0 | 28 GB | 29.8 GB | Fits easily | ~25 tok/s |
| FP16 | 53 GB | 54.8 GB | Fits easily | ~13 tok/s |
Estimates. Needs = weights + 1.8 GB for KV cache and runtime at modest context. Speed is single-stream decode scaled from the DGX Spark (GB10)'s 273.2 GB/s bandwidth (Estimated from memory bandwidth (llama.cpp decode)). Long contexts need more memory and run slower.

Frequently asked
Quick answers
Can the NVIDIA DGX Spark (GB10) run Gemma 4 26B A4B?
Yes. Gemma 4 26B A4B fits the DGX Spark (GB10)'s 128 GB at Q4_K_M (about 16.8 GB needed), running at an estimated 46 tok/s. There's room for up to FP16 if you want higher quality.
How much VRAM does Gemma 4 26B A4B need?
About 15 GB of weights at Q4_K_M, 28 GB at Q8_0 and 53 GB at FP16. Add roughly 1.8 GB for the KV cache and runtime at modest context lengths.
How fast is Gemma 4 26B A4B on the DGX Spark (GB10)?
Roughly 46 tokens per second at Q4_K_M (single user, llama.cpp-style decode). This is an estimate from the DGX Spark (GB10)'s 273.2 GB/s memory bandwidth; as a mixture-of-experts model only about 4B parameters are read per token, which is why it is faster than its size suggests.
