What is the issue?

Update 4/4: Issue related to the FA feature being turned on.

Models seems to load into GPU then jump to CPU. PS shows model running in GPU.

I tried 2b and 4b bf16, and the 26/31b 4q on 5090 with context set to 130k

Example output from ps.
gemma4:e2b-it-bf16 850bc7fea32f 12 GB 100% GPU 130000 57 minutes from now

Original GitHub issue: https://github.com/ollama/ollama/issues/15237 ### What is the issue? **Update 4/4**: Issue related to the FA feature being turned on. Models seems to load into GPU then jump to CPU. PS shows model running in GPU. I tried 2b and 4b bf16, and the 26/31b 4q on 5090 with context set to 130k Example output from ps. gemma4:e2b-it-bf16 850bc7fea32f 12 GB 100% GPU 130000 57 minutes from now From the log:

I can confirm that Gemma4 models make very little use of the GPU. It looks like Ollama is offloading some layers to the CPU. May only need some optimization.

Cannot reproduce here, the graphics card takes the load.

I just ran gemma4:2b, 4b, and 26b models and all of them showed a small spike on both CPU and GPU at the beginning of processing, thereafter the CPU dropped out and just the GPU stayed loaded up until the request is complete. Ryzen AI 9 HX 370 w/ Radeon 890M.

Sorta the same. Percentages displayed by ollama (below) are accurate though. Gemma4 (e2b q4) not using much of the 8.1GB available on the dedicated RTX 4070 Laptop GPU. ~2.4GB used with 16.4K context, then ~2.9GB used with 32.8K context, and then finally ~4GB used with 65.5K context; interestingly the a4b model had less such issues with 6.6GB on the GPU with a low context length!

Env: Ubuntu 24.04, NVIDIA driver 580.126.09, CUDA 13.0, dual 3090 + 5090 (54GB VRAM)

  1. Initially I had OOM issues - manually setting flash attention fixed this (I can now easily do 128k context window and probably >200k)

Fix: Flash attention (+ reduced context) in /etc/systemd/system/ollama.service.d/override.conf:

  [Service]                                                                                                                                                                                
  Environment="OLLAMA_FLASH_ATTENTION=1"                                                                                                                                                   
  # Environment="OLLAMA_CONTEXT_LENGTH=128000"

Result: 912 tk/s prompt and 45 tk/s eval via ollama run --verbose, ollama ps reports 100% GPU, 61/61 layers offloaded.

  1. Remaining issue: Still significant CPU compute despite "100% GPU"
  • Logs show 1.2 GiB of model weights and 1.2 GiB compute graph remain on CPU despite all 61/61 layers reported as offloaded:
  model weights device=CUDA0 size="10.0 GiB"
  model weights device=CUDA1 size="8.4 GiB"                                                                                                                                                
  model weights device=CPU   size="1.2 GiB"
  compute graph  device=CPU   size="1.2 GiB"
  • perf top during inference confirms real work on CPU, not just sampling:
    54.46% libggml-cpu-haswell.so ggml_compute_forward_flash_attn_ext
    39.58% libggml-cpu-haswell.so ggml_vec_dot_f16
  • Things that did NOT help with this issue:
    - OLLAMA_GPU_OVERHEAD=0 — no change in allocation; 1.2 GiB of weights remained on CPU
    - OLLAMA_KV_CACHE_TYPE=q8_0 — collapsed to single GPU, different issues

Unsolved: What are the 1.2 GiB of CPU-side weights and why do flash attention + dot product ops run on CPU despite full layer offload? If anyone has insight, would appreciate it.

Edit: It seems the 1.2GiB are the vision encoder weights that are not offloaded by Ollama/llama.cpp to the GPU. Might be related to #11422

Same problem:

ollama ps reports 100% GPU, but logs show some stuff getting loaded onto CPU.

Eyeballing to top and nvtop, it looks like 3/4 of the work is being done by the CPU, and overall performance is much slower than expected. GPU is only running at ~20% capacity

AMD RYZEN AI MAX+ 395 w/ Radeon 8060S here.

I see the same behaviour - as a prompt is evaluated, the gpu usage slowly goes down and the cpu usage up. i have tried with rocm, vulkan and it's the same thing.

it shows 100% gpu with both gemma4:26b and gemma4:31b but both of them are definitely using cpu!

I have the same issue. I have 2 Nvidia RTX 3090s and I have conky loaded so I can see the memory of each GPU in real time.

The memory ping-pongs between the 2 GPUs until it finally starts executing on the CPU:

NAME ID SIZE PROCESSOR CONTEXT UNTIL
gemma4:31b 6316f0629137 63 GB 100% CPU 262144 4 minutes from now

All the other modesl run on the GPUs fine.

Another issue is that when I switch to another model, and it's running on the GPUs, Ollama never unloads gemma4:32b and my CPU load is maxed out, the temperatures and fans go way up, and I have to run "sudo systemctl restart ollama" to get everything back to normal.

@PurpleBanana-ai commented on GitHub (Apr 3, 2026):

My apologies in advance if this is not the appropriate format for posting this info, I generally do not post on these. Running with Open WebUI is worse, especially with any type of tool call like web search, but for this case below, this is Ollama straight in the terminal. FYI, I am showing the same issue with a gguf model from unsloth for gemma4, not just the ones directly downloaded from Ollama. Was seeing my cpu package temp touch 60c+, which is not something I see with my cooling unless running intense benchmarks, never for inference or even diffusion.

Setup
Debian 13, Cuda 13.2, Driver 595.58.03
i9-14900k 790 chipset
94GB DDR5 6400
m.2 NVME (CPU Side PCIE Bus)
GPU 0: RTX 5090 32GB (CPU Side PCIE Bus - PCIE5 Slot x8)
GPU 1: RTX 3090 24GB (CPU Side PCIE Bus - PCIE 5 Slot x8)-yes the GPU is at PCIE4
GPU 2: RTX 5070ti 16GB (Chipset Side PCIE Bus - PCIE4 16x slot at x4)
GPU 3: RTX 5070ti 16GB (Chipset Side PCIE Bus - m.2 PCIE4 x4 to Occulink EGPU)
(no need to dog the frankenrig, she is fine, this is the only model I am having issues with, I will try it on llama.cpp and vLLM as well later.)

Same issues as above just a different config, but only showing issue with gemma4, any of the model versions, any quant, any ctx size. I am seeing the model weights offloaded to the CPU in the logs below. I have tried creating model files with static offloading gpu layers to 999 but no difference. gemma4 is also running very slow, even if I pin the 31B at 4K_M quant to my 5090 with 8192 ctx, it is no different than across multiple GPU's. ~13tps - 15tps for gemma 4. Load time is as expected across multiple cards with this config, not an issue.

This example and the logs is with the following Modelfile (FA on in env, no docker):

FROM gemma4:31b-it-q8_0
PARAMETER temperature 1.0
PARAMETER top_p 0.95
PARAMETER top_k 65
PARAMETER num_ctx 65536

qwen3.5 32B A3B Q8 is fine even at 245,760 ctx.
qwen3-next:80b-a3b-thinking-q4_K_M is fine at 204,800 ctx.

FYI Comparison Same Basic Prompt, Think mode enabled for gemma4 (doesn't change the issue if I turn it off):

gemma4
ollama run gemma4-31b-q8_0-custom:latest --verbose

Not sure it helps, happy to provide more info.

<!-- gh-comment-id:4184023295 --> @PurpleBanana-ai commented on GitHub (Apr 3, 2026): My apologies in advance if this is not the appropriate format for posting this info, I generally do not post on these. Running with Open WebUI is worse, especially with any type of tool call like web search, but for this case below, this is Ollama straight in the terminal. FYI, I am showing the same issue with a gguf model from unsloth for gemma4, not just the ones directly downloaded from Ollama. Was seeing my cpu package temp touch 60c+, which is not something I see with my cooling unless running intense benchmarks, never for inference or even diffusion. Setup Debian 13, Cuda 13.2, Driver 595.58.03 i9-14900k 790 chipset 94GB DDR5 6400 m.2 NVME (CPU Side PCIE Bus) GPU 0: RTX 5090 32GB (CPU Side PCIE Bus - PCIE5 Slot x8) GPU 1: RTX 3090 24GB (CPU Side PCIE Bus - PCIE 5 Slot x8)-yes the GPU is at PCIE4 GPU 2: RTX 5070ti 16GB (Chipset Side PCIE Bus - PCIE4 16x slot at x4) GPU 3: RTX 5070ti 16GB (Chipset Side PCIE Bus - m.2 PCIE4 x4 to Occulink EGPU) (no need to dog the frankenrig, she is fine, this is the only model I am having issues with, I will try it on llama.cpp and vLLM as well later.) Same issues as above just a different config, but only showing issue with gemma4, any of the model versions, any quant, any ctx size. I am seeing the model weights offloaded to the CPU in the logs below. I have tried creating model files with static offloading gpu layers to 999 but no difference. gemma4 is also running very slow, even if I pin the 31B at 4K_M quant to my 5090 with 8192 ctx, it is no different than across multiple GPU's. ~13tps - 15tps for gemma 4. Load time is as expected across multiple cards with this config, not an issue. This example and the logs is with the following Modelfile (FA on in env, no docker): ```bash FROM gemma4:31b-it-q8_0 PARAMETER temperature 1.0 PARAMETER top_p 0.95 PARAMETER top_k 65 PARAMETER num_ctx 65536 ``` qwen3.5 32B A3B Q8 is fine even at 245,760 ctx. qwen3-next:80b-a3b-thinking-q4_K_M is fine at 204,800 ctx. FYI Comparison Same Basic Prompt, Think mode enabled for gemma4 (doesn't change the issue if I turn it off): **gemma4** ollama run gemma4-31b-q8_0-custom:latest --verbose >>> <|think|> hi gemma, its nice to meet you! would you mind sharing with me a detailed explanation of new capabilities?

fwiw, seeing the same behavior on a mac in ollama 0.20:

gemma4:31b
M3 MAX Processor with 128GB of ram.

ollama ps shows the model loaded with 100% GPU, but mactop shows 600+ CPU utilization with very little GPU.

Hm, weirdly with version 20.2 I ran it inside ollama, 32k context, no cpu usage, only one thread on my cpu being used, but answer came quick.
Then tested same 32k context via openclaw, all 32 CPU cores are running now o.O

Based on my observations, the glitch is triggered specifically when sending a second prompt. This behavior is highly unusual.

My use case involves using a separate Rust app that calls the API via the TCP port (via the rig crate). That works fine and the model runs under GPU when called via API calls from the socket as well as via the ollama CLI. I don't know what the your Python calls would be doing differently than that.

@somera and others, try the 26b or smaller models instead of 31b. 31b seems to need WILDLY more video RAM than it probably aught to. I have 96G video memory available too (shared) and it taken north of 60G to run the 26b model. The 31b model starts loading then runs out of ram and starts chucking through something on one CPU. I suspect a lot of the issues in this thread probably have memory issues as their root cause, not CPU/GPU routing.

As I just mentioned the 26b model eats through about 60GB VRAM when I run it. Try one of the even smaller models.

@mazphilip commented on GitHub (Apr 4, 2026):

I did more digging, this seems to be a Flash Attention issue with Gemma4 (upstream, either Flash attention or llama.cpp) - somehow only triggered when traying to run coding agents? (ollama launch claude, ollama launch vscode)

  • It does seem true that the vision layers are always CPU offloaded, but the big issues seem FA related.

While you can force the FA usage, which makes ollama allocate the memory on the GPU(s), but once you run it (with longer context?), something happens and it moved all the calculation to the CPU.

I get very good performance (1500tk/s prompt, 50tk/s eval) when running (using /etc/systemd/system/ollama.service.d/override.conf)

  • no FA
  • Smaller than typica context: 96k (for 54GB VRAM) - to account for inefficient usage due to no FA

Resolution steps:

  1. Fix FA usage with llama.cpp (claude telling me it might be the global attention layers with key_length=512 not properly mapped in llama.cpp - looking into this rn
    1. EDIT: seems this is already fixed in llama.cpp - https://github.com/ggml-org/llama.cpp/releases/tag/b8609
  2. Move vision layers to GPU (but I can also see how this is personal use case specific)
<!-- gh-comment-id:4187455580 --> @mazphilip commented on GitHub (Apr 4, 2026): I did more digging, this seems to be a Flash Attention issue with Gemma4 (upstream, either Flash attention or llama.cpp) - somehow only triggered when traying to run coding agents? (ollama launch claude, ollama launch vscode) * It does seem true that the vision layers are always CPU offloaded, but the big issues seem FA related. While you can force the FA usage, which makes ollama allocate the memory on the GPU(s), but once you run it (with longer context?), something happens and it moved all the calculation to the CPU. I get very good performance (1500tk/s prompt, 50tk/s eval) when running (using `/etc/systemd/system/ollama.service.d/override.conf`) * no FA * Smaller than typica context: 96k (for 54GB VRAM) - to account for inefficient usage due to no FA Resolution steps: 1.

I can confirm @mazphilip finding(s) with respect to FA. Turning off FA in the service seems to solve the issue of CPU offload. Note that the CPU offload only seems to occur when calling via the API. Ollama CLI works fine.

My example usage uses gemma4:31b, with 128K context and takes about 71 GB VRAM. With FA disabled this config works well.

I'm not using coding agents with ollama and I have the issues with ollama run <model> and from Open WebUI and small context (4096).

I was able to confirm that disabling FA caused the model layers to stay on the GPU now.

Can confirm, disabling FA on Ollama seems to correctly offload everything to GPU now.

@viba1 commented on GitHub (Apr 4, 2026):

On my side, disabling FA works correctly for models running 100% GPU, but the issue remains for models that split their workload between the CPU and GPU.

For exemple:
Gemma4:26b: 21% CPU / 79% GPU ; ~ 1.2 token/s
Gemma3:27b: 19% CPU / 81% GPU ; ~3 token/s

I also can confirm, turning OLLAMA_FLASH_ATTENTION=false (or 0 as some suggest - both seem to work) will immediately sharply boost the performance of Gemma 4 (installed: gemma4:31b). Before 20 t/s - after 60 token/s.

another data point that disabling FA works if you have enough VRAM (in my case Ryzen AI Maz 395, with 64 GB allocated to the GPU): before I was seeing between 25 and 75% GPU usage with gemma4:26b and 21 GB of VRAM used, now I see close to 100% GPU use and 38 GB of VRAM used (and it is much faster)

ollama ps said 100% GPU in both cases.

Turing off thinking does make it faster with about 19 t/s
66%/34% CPU/GPU

Doesn't make much difference for me

OLLAMA_FLASH_ATTENTION	1
OLLAMA_MAX_LOADED_MODELS	1
OLLAMA_NUM_PARALLEL	1

I am using docker with gemma4:e4b and OLLAMA_NEW_ENGINE=true

Confirmed, with OLLAMA_FLASH_ATTENTION=1 on Gemma4:26B there is heavy CPU usage (50-60%) and eval token speed hovers around 30 token/s, even for the e4b variant!
with OLLAMA_FLASH_ATTENTION=0 token speed on Gemma4:26B jumps to 108 tokens/s on RTX 3090

In both cases Ollama reports full GPU inference:
