Run Ollama with IPEX-LLM on Intel GPU

ollama/ollama is popular framework designed to build and run language models on a local machine; you can now use the C++ interface of ipex-llm as an accelerated backend for ollama running on Intel GPU (e.g., local PC with iGPU, discrete GPU such as Arc, Flex and Max).

See the demo of running LLaMA2-7B on Intel Arc GPU below.

Quickstart

1 Install IPEX-LLM for Ollama

IPEX-LLM’s support for ollama now is available for Linux system and Windows system.

Visit Run llama.cpp with IPEX-LLM on Intel GPU Guide, and follow the instructions in section Prerequisites to setup and section Install IPEX-LLM cpp to install the IPEX-LLM with Ollama binaries.

After the installation, you should have created a conda environment, named llm-cpp for instance, for running ollama commands with IPEX-LLM.

2. Initialize Ollama

Activate the llm-cpp conda environment and initialize Ollama by executing the commands below. A symbolic link to ollama will appear in your current directory.

LinuxWindows

conda activate llm-cpp
init-ollama

Now you can use this executable file by standard ollama’s usage.

3 Run Ollama Serve

You may launch the Ollama service as below:

LinuxWindows

export OLLAMA_NUM_GPU=999
export no_proxy=localhost,127.0.0.1
export ZES_ENABLE_SYSMAN=1
source /opt/intel/oneapi/setvars.sh

./ollama serve

Note

Please set environment variable OLLAMA_NUM_GPU to 999 to make sure all layers of your model are running on Intel GPU, otherwise, some layers may run on CPU.

Note

To allow the service to accept connections from all IP addresses, use OLLAMA_HOST=0.0.0.0 ./ollama serve instead of just ./ollama serve.

The console will display messages similar to the following:

4 Pull Model

Keep the Ollama service on and open another terminal and run ./ollama pull <model_name> in Linux (ollama.exe pull <model_name> in Windows) to automatically pull a model. e.g. dolphin-phi:latest:

5 Using Ollama

Using Curl

Using curl is the easiest way to verify the API service and model. Execute the following commands in a terminal. Replace the <model_name> with your pulled model, e.g. dolphin-phi.

LinuxWindows

curl http://localhost:11434/api/generate -d '
{ 
   "model": "<model_name>", 
   "prompt": "Why is the sky blue?", 
   "stream": false
}'

Using Ollama Run GGUF models

Ollama supports importing GGUF models in the Modelfile, for example, suppose you have downloaded a mistral-7b-instruct-v0.1.Q4_K_M.gguf from Mistral-7B-Instruct-v0.1-GGUF, then you can create a file named Modelfile:

FROM ./mistral-7b-instruct-v0.1.Q4_K_M.gguf
TEMPLATE [INST] {{ .Prompt }} [/INST]
PARAMETER num_predict 64

Then you can create the model in Ollama by ollama create example -f Modelfile and use ollama run to run the model directly on console.

LinuxWindows

export no_proxy=localhost,127.0.0.1
./ollama create example -f Modelfile
./ollama run example

An example process of interacting with model with ollama run example looks like the following:
