In this tutorial, we'll show how to integrate Ollama with Jan using the first method. We will use the llama2 model as an example.

Step 1: Start the Ollama Server​

  1. Choose your model from the Ollama library.
  2. Run your model with this command:
ollama run <model-name>
  1. According to the Ollama documentation on OpenAI compatibility, you can connect to the Ollama server using the web address http://localhost:11434/v1/chat/completions. To do this, change the openai.json file in the ~/jan/engines folder to add the Ollama server's full web address:
~/jan/engines/openai.json
{
  "full_url": "http://localhost:11434/v1/chat/completions"
}

Step 2: Model Configuration​

  1. Navigate to the ~/jan/models folder.
  2. Create a folder named (ollam-modelname), for example, lmstudio-phi-2.
  3. Create a model.json file inside the folder including the following configurations:
  • Set the id property to the model name as Ollama model name.
  • Set the format property to api.
  • Set the engine property to openai.
  • Set the state property to ready.
