What is Ollama?

Before we dive into the setup, let’s take a moment to understand what Ollama truly is.

To make sure your chat setup goes smoothly, you'll want to ensure your system meets the necessary requirements. While the system requirements may vary based on the models you intend to run, general recommendations include:

Windows, macOS, or Linux installation capabilities (Ollama is quite versatile!)
At least 8GB RAM for 7B models, 16GB RAM for the 13B models, and 32GB RAM for 33B models
Some decent CPU power, preferably with a GPU for faster processing if you want to run large models without hiccups

Quick Customization: If you want to do something fancy, feel free to customize your model's prompts using the Modelfile.

Customizing Your Chatbot

Customization is where you let your creativity shine! 🌞 Let’s customize your chatbot using the Modelfile to fine-tune its responses:

Create a file named
1Modelfile
& input the model instructions, such as:
1 2 3 4 5llama3.1 # set temperature 1 PARAMETER temperature 1 # system message SYSTEM """ Mario Super Mario Bros. Answer Mario, assistant, only. """
Save & then run:
1 2 3bash ollama create mario -f ./Modelfile ollama run mario

Advanced API Usage

Ollama also offers an API to interact with your models programmatically! This is especially useful when building applications. Here’s how you can generate responses via cURL:

1
curl http://localhost:11434/api/generate -d '{"model":"llama3.1", "prompt":"Why is the sky blue?"}'

You can also use the Chat API for keeping chat history intact:

1
curl http://localhost:11434/api/chat -d '{ "model": "llama3.1", "messages": [{ "role": "user", "content": "why is the sky blue?" }] }'

Optional Libraries

If you’re a developer looking to integrate Ollama into your applications, utilize the following libraries:

ollama-python
ollama-js
These libraries make working with Ollama's extensive functionalities a breeze, allowing you to integrate AI capabilities into web and mobile applications.

Troubleshooting Common Issues

As with any setup, issues may arise. Here are some common problems & solutions:

1localhost
with
