Models with a thinking mode spend extra tokens thinking, so their speed thresholds are 1.5× stricter (30 / 12 / 3 tok/s). With thinking turned off, a model may do one grade better.

S = Runs great · A = Runs well · B = Runs slowly · F = Won't run
At Q4_K_M the verdict stays Runs well up to 128k context with an f16 KV cache, and up to 256k with q8_0.
Estimated speed
- Generation
- est. 59.2 tok/s (41.4–76.9, theoretical estimate ±30%)
- Prompt processing
- Prompt-processing estimates only apply when the whole model runs on the GPU.
Why this verdict: Not fully on the GPU — Runs great needs the whole model in GPU memory

Keep only the experts in system RAM
--n-cpu-moe 6 keeps only the experts of the first 6 layers in system RAM and everything else on the GPU (this estimate).
How to run it
Commands for the UD-Q4_K_M file. Both tools download from Hugging Face on first run.
File: gemma-4-26B-A4B-it-UD-Q4_K_M.gguf (16.95 GB) from unsloth/gemma-4-26B-A4B-it-GGUF.
llama-server -hf unsloth/gemma-4-26B-A4B-it-GGUF:UD-Q4_K_M -c 8192 -ngl all --n-cpu-moe 6 -fa on- -ngl all loads every layer on the GPU.
- --n-cpu-moe 6 keeps the experts in the first 6 layers in system RAM; the remaining 24 layers with experts keep them on the GPU. This estimate assumes the same split.
- If loading fails with an out-of-memory error, raise the value to 7, or to 8 if that isn't enough.
- llama.cpp b7410 (December 2025) and later split the model in a similar way on their own if you leave out -ngl and --n-cpu-moe.
- -fa on enables flash attention (needed for KV cache quantization).
- --cache-type-k q8_0 --cache-type-v q8_0 shrinks the KV cache to 0.09 GB at 8k context.
PowerShell (quit the Ollama tray app first):
$env:OLLAMA_CONTEXT_LENGTH="8192"; ollama serve
ollama run hf.co/unsloth/gemma-4-26B-A4B-it-GGUF:UD-Q4_K_M- Ollama defaults to 4k context on GPUs under 24 GB. Set OLLAMA_CONTEXT_LENGTH when starting the server, or /set parameter num_ctx inside the chat.
- Ollama 0.30 and later automatically keep part of the experts in system RAM to fit your VRAM. Older versions split whole layers instead, which is much slower.
/set parameter num_ctx 8192

Frequently asked questions
Can I run Gemma 4 26B-A4B on the GeForce RTX 5060 Ti 16GB?
Q4_K_M keeps attention and the experts of 24 layers on the GPU (15.4 GB) and the remaining experts in 2.9 GB of system RAM: Runs well, est. 59.2 tok/s (41.4–76.9, theoretical estimate ±30%). Q4_K_M needs 17.7 GB at 8k context; this setup has 15.4 GB of usable memory and 28.0 GB of free system RAM.
How much context can Gemma 4 26B-A4B use on the GeForce RTX 5060 Ti 16GB?
At Q4_K_M the verdict stays Runs well up to 128k context with an f16 KV cache (2.7 GB of KV) and up to 256k with a q8_0 KV cache (2.9 GB). The model supports up to 256k.
Which quant should I use, and how fast is it?
Q4_K_M (16.95 GB) is the recommended balance: Runs well, est. 59.2 tok/s (41.4–76.9, theoretical estimate ±30%). The largest tracked file that still gets Runs well is Q8_0 (26.86 GB), est. 31.4 tok/s (21.9–40.8, theoretical estimate ±30%).
Speeds are estimates from memory bandwidth, calibrated against public benchmarks, and each one comes with an error band and a confidence label. Real results vary with drivers, backend, context length and thermals.
